If you feel that you have higher performing glass then the average home, try to turn the level up slightly above recommended setting. Try this when the sun is not shining directly on your home because the solar radiant heat may prevent the moisture from forming, but as soon as the sun goes down it may form at night meaning the level is too high for your glass.
The only difference is that the digital humidistat has the ability to bring on the furnace fan on a call for humidity whereas the analog humidistat must wait for a call for heat from the thermostat for the furnace fan to engage and then humidity can be automatically added to the home.
To set the moisture level, both humidistats operate identically. After allowing to operate for 24 to 48 hours, you may notice that minor adjustments may need to be made. If you feel the home is too dry, increase by increments of 1 from your initial setting and then wait 24 to 48 hours before adjusting higher again. If you initially notice water forming on your glass or after adjusting upwards, you will need to lower the setting by going down one level and allowing 24 to 48 hours to gauge if adjustment is satisfactory.
How can you tell if your Aprilaire humidifier is working? If water is not draining from your humidifier , you first need to determine if your Aprilaire Humidifier is working properly. You may do so by turning up the heat temperature 5 degrees above the current room temperature on your thermostat and setting your manual humidistat to call for humidity.
Ampar Muriedas Explainer. Should humidifier run when furnace is off? Most humidifiers have a humidistat that senses the current humidity and turns the humidifier on and off depending on the humidistat setting.
The humidistat is typically installed on a furnace duct, usually close to the humidifier. A humidifier can only put moisture into the air when the furnace fan is running. Keri Gabarra Pundit. Do furnace humidifiers cause mold? Because the interior of a furnace humidifier is a moist environment, it is at risk for mold growth. Mold can grow on the absorbent padding inside the humidifier or on the interior walls. If mold growth goes unchecked, the furnace can blow mold spores into your home.
Lika Casau Pundit. Where should I set my humidistat in the winter? Set the humidistat knob on the humidifier to the following winter settings as recommended by the Ask the Builder website. If the outdoor temperature is near F, set the humidistat to 20 percent. If the temperature is near 0 F, set the humidistat to 25 percent. Hobert Jubert Pundit. How do I turn off my humidifier in the summer? Step 1 — Turn the humidistat to the off position or the lowest percent of relative humidity.
Step 2 — Close the duct damper or turn it to the summer position. Step 3 — Turn off the water-supply. Step 4 — After removing the pad, float assembly, and pan, the parts can now be cleaned. Praxedes Bruening Pundit. Should humidifier be on in winter? Moisture levels in the air and humidifiers. Anina Mirabel Pundit. Should I run my humidifier in the summer? Tanit Gerg Teacher.
When should you turn off your humidifier? However, the air in the summer is moist so using a humidifier is unnecessary and it can actually cost you money. If you forget to turn off your humidifier and close the damper in the spring, your air conditioner will have to work harder and longer to remove the excess moisture.
Shamira Itxasertz-Alde Teacher. After clearing and re-installing the orifice and strainer be sure to double wrench all water connections , turn the humidifier control dial above the click point and water should be coming out the drain line. Aprilaire humidifiers are designed to efficiently use water for the evaporation process. These feed rates will not activate tankless water heater since tankless water heaters typically require a certain gallons per minute to activate.
Aprilaire recommends a conventional water heater with the ability to handle the household requirement for hot water with the feed rate for the Aprilaire model factored in. Aprilaire humidifiers are packaged with one of two types of humidifier controls, a manual non digital humidifier control and an automatic digital humidifier control. The models with an M in the model number M, M, M, M and the models and include the manual humidistat see below. For the models M, M, M and M, the manual humidistat can be installed in the cold air return duct or the living area.
For the model or the manual humidistat must be installed in the living area. The models , , , and include the automatic digital humidifier control see below which is designed to only be installed on the cold air return duct of the HVAC system. It cannot be installed on a wall in the living area as airflow will not adequately get to the humidity sensor on the control.
This results in inaccurate humidity levels. The Aprilaire digital humidifier control can operate in automatic or manual mode, but regardless of the mode, the digital control requires the HVAC system fan to be operating, a water supply, and a heat source in order to create humidity.
Whenever the HVAC system is moving air a heat call or a fan call the digital humidifier control will add humidity if the humidification level is below the desired level.
If the digital humidifier control is wired to operate the humidifier during an HVAC fan call, the humidifier will need to be supplied with hot water as that is the only heat source available.
A fan call simply circulates room temperature air in the home, typically 70F, which is not adequate to cause evaporation. In the automatic mode an outdoor sensor is installed. This sensor continuously reports changes in the outdoor temperature to the digital humidifier control located in the cold air return duct or outside the home.
The digital humidifier control uses this information to determine if the home requires additional humidity, to ensure the optimum humidification level is maintained. In manual mode there is no outdoor sensor. As a result the digital humidifier control will require regular manual adjusting as the outdoor temperature changes, so the home is not over or under humidified. A flashing red light the call dealer for service indicator means the control is not operating properly and the installer needs to check the operation of the control.
Anytime the red light is flashing a code will be displayed on the LCD screen. The code may be cleared by rotating the control knob on the humidifier control to the test reset position. Return the control knob to its previous position. If the error code has cleared the humidifier control has returned to normal operation. If not, the HVAC installer will need to review the wiring to determine if the control requires replacement.
The Aprilaire manual humidistat is designed to be installed on the cold air return duct or on an interior wall in the living area of the home. To determine the relative humidity in the home, slowly turn the knob on the control clockwise and counterclockwise and listen for 2 clicks.
The actual relative humidity in the home is between the 2 clicks. It is important to anticipate a drop in outdoor temperature and reduce the humidity setting in order to avoid excess condensation. The excess condensation occurs because the indoor relative humidity is higher than what the home can support for the current outdoor temperature. To adjust the humidity setting, simply rotate the control knob to the desired setting. Provided the HVAC system fan is operating and the humidification level is lower than the new set point, the manual humidistat will activate the humidifier.
All Aprilaire humidifiers include a control which is either located on the cold air return duct or in the living area of the home. Below are a few of the controls we have offered since our humidifiers were introduced in The humidifier controls which have an off position should be placed in the off position. If the humidifier control does not have an off position simply turn the dial to the lowest setting and follow the applicable steps below.
Annual summer shutdown for bypass models series, series and series close the bypass damper, which is a part of the humidifier, with the small damper handle.
The model series and model steam humidifier simply require the adjustment of the humidifier control where applicable. Figure E. The Aprilaire model steam humidifier is designed to operate with , volts or volts, however all current models are defaulted to operate with volts for the maximum humidification output. At volts the would cost about 25 cents an hour to operate. The run time of the humidifier will vary based on the age, cubic footage square footage times ceiling height and tightness of the home, as well as the operating time of the HVAC heating system.
However, it is unlikely it will run 12 hours out of every 24 hour period and may be much less per month than the amount above. At volts, the could cost about 10 cents per hour to operate. While we do offer the water solenoid valve on our Estore , it is the only electrical component we have available for direct purchase.
From a safety standpoint, and to insure proper humidifier operation, electrical components such as the water solenoid valve should be installed by a local Healthy Air Pro.
The warranty of any electrical component will be void if it is not installed by a licensed HVAC installer. If you need the name of a local Healthy Air Pro , please use our Dealer locator:. The local Healthy Air Pro who installed your Aprilaire humidifier can help you obtain these parts, or you can search for another local Healthy Air Pro using our Dealer Locator. We also offer an E-Store where you may purchase select humidifier parts.
These dehumidifiers , A, , A, and A include an onboard control which will automatically turn on the internal blower for 3 minutes at the end of each cycle period to sample the air and measure moisture level of the incoming ambient air.
This process determines if the relative humidity of the incoming air is above the set point of the control dial, 1—7. When the relative humidity in the home is above the set point, the dehumidifier will then energize its compressor and continue running until the set point is reached. The cycle period can be customized to 30 minutes, 1, 2, or 3 hours.
The default is 1 hour. As a result, our dehumidifiers will remove less moisture at lower indoor ambient temperatures. Dehumidifiers, including Aprilaire dehumidifiers, are not designed to pull moisture off surfaces like windows, walls and floors. In order for any dehumidifier to attempt to remove moisture, the moisture needs to be in the air. Our Aprilaire dehumidifiers usually will not operate in the winter. If the dew point is lower than the surface temperature, condensation will not form.
The Aprilaire models , , , and W include an onboard control which will automatically turn on the internal blower for 3 minutes at the end of each hour to sample the air and measure the moisture level of the incoming ambient air. While this sample rate cannot be adjusted, changing the set point to a number lower than the current set point will cause the dehumidifier to start sampling right away. The Aprilaire Model has a service life of one year.

What is the advantage of installing an Aprilaire zoned comfort control system in a home as it is being built versus in an existing home?
An Aprilaire zoned comfort control system can be installed in a home under construction as well as in an existing home. Your HVAC installer is able to run wiring through open framework and between floors, therefore resulting in savings in installation costs.
In addition, required ductwork sizing and system balancing are also easier and less expensive to accomplish while the home is under construction. In an existing home your HVAC installer will have to find a way to run wire to the thermostat locations and the HVAC duct work may require modification. Your HVAC installer can best explain what will be required for adding an Aprilaire zoned comfort control system in your existing home. What is the maintenance required with an Aprilaire zoned comfort control system?
The Aprilaire zoned comfort control system does not require maintenance under normal operation as it is simply a control to operate the HVAC system. Changes in living habits or remodeling of the home will typically require adjustments to the system by the HVAC installer. Why does the heating and cooling system fan continue to run after the thermostat stops calling? The Aprilaire zoned comfort control system provides comfort, convenience and energy savings.
It does this by only distributing conditioned air to the area s of the home requiring it. This allows the area s requiring conditioned air to reach their desired temperature faster resulting in less operating time for the heating and cooling system. This provides energy savings since the Aprilaire zoned comfort control system reduced the energy requirements to the seldom used areas non-calling zones of the home.
The Aprilaire zoned comfort control system ensures that only the necessary amount of energy is used throughout the home. What is an Aprilaire zoned comfort control system and what are the components? The Aprilaire zoned comfort control system consists of a control panel, thermostats and dampers installed in conjunction with your existing heating and cooling forced air system.
Thermostats connected to the Aprilaire zoned comfort control panel call for conditioned air whenever the temperature in the zone s is not at the desired set point. The Aprilaire zoned comfort control panel sends the call on to the heating and cooling equipment. Zone dampers, located in the forced air heating and cooling system, for zones which are not calling for conditioned air, are powered closed by the Aprilaire zoned comfort control panel.
The heating and cooling system then distributes the conditioned air through the duct work to the calling zones. Will the Model Control Panel work with zone dampers that are normally-closed powered-open, as well as normally-open powered-closed?
All Aprilaire zoned comfort control panels will work with normally-open, powered-closed zone dampers as well as normally-closed, powered-open zone dampers. All Aprilaire zone dampers are normally-open, powered-closed dampers. This means with no power going to the zone damper it will always be open. When a zone calls for conditioning, the Aprilaire zone dampers in the zones not calling will be sent a continuous 24 volt power supply from the Aprilaire zoned comfort control panel to be powered closed.
The Aprilaire zoned comfort control panel will continuously power the normally-open, powered-closed zone damper until the conditioned air call in the calling zone is complete. Once the call is complete, the continuous 24 volt power supply is stopped by the Aprilaire zoned comfort control panel and the Aprilaire zone dampers in the non-calling zones return to their normally-open position.
The NC and C terminals on the Aprilaire zoned comfort control panel send out 24 volts continuously while the Aprilaire zoned comfort control panel is not making any calls for conditioned air. If a normally-closed, powered-open damper is used and connected to the NC and C terminals, our Aprilaire zoned comfort control panel will send a continuous 24 volt power supply to the zone damper to keep it open. The zone damper must be capable of receiving continuous 24 volt power.
The manufacturer of the normally-closed, power-open damper you selected should be able to determine whether or not their dampers can function reliably with continuous 24 volt power. Can Aprilaire zoned comfort control panels work with three wire zone dampers that are powered-open and powered-closed?
All Aprilaire zoned comfort control panels will work with normally-open, powered-closed zone dampers as well as normally-closed, powered-open zone dampers and with dampers which are powered-open and powered-closed. When a powered-open, powered-closed damper is used the power- to- open terminal on the damper wires to the NC terminal on the Aprilaire zoned comfort control panel, the power- to- close terminal on the damper wires to the NO terminal on the Aprilaire zoned comfort control panel and the Common terminal on the damper wires to C terminal on the Aprilaire zoned comfort control panel.
Since the NC and C terminals on the Aprilaire zoned comfort control panel send out 24 volts continuously while the Aprilaire zoned comfort control panel is not making any calls for conditioned air, our Aprilaire zoned comfort control panel will send a continuous 24 volt power supply to the zone damper to keep it open.
When a zone calls for conditioned air, 24 volts is sent out the NO and C terminals to power closed the zoned dampers in the zones not requiring conditioned air.
The Aprilaire zoned comfort control panel will continue to send 24 volt power out the NC and C terminals to the zone damper in the zone calling for conditioned air to keep it open. Once the call is complete 24 volt power is removed from NO and C terminals in the non-calling zones and instead 24 volt powers is sent out the NC and C terminals to power the dampers back open.
How do I know which zone is calling for conditioning through the Aprilaire zoned comfort control panel? All Aprilaire zoned comfort control panels include lights which are illuminated when the NO and C damper terminals for that zone are powered. Since Aprilaire dampers are normally-open, powered-closed, Aprilaire dampers are wired to the NO and C terminals. The Aprilaire zoned comfort control panel is designed to illuminate a damper light when the Aprilaire zoned comfort control panel powers the damper closed.
This occurs whenever there is no call for conditioned air in a specific zone. A zone with the damper light not illuminated indicates the zone is calling for conditioned air. Heat recovery ventilators transfer temperature from the high temperature airstream to the low temperature airstream.
Energy recovery ventilators transfer both temperature and moisture. Since transferring temperature and moisture has benefits in the winter and summer, ERVs are the better choice in climates with high humidity. Is a ventilation system like the Aprilaire Model Energy Recovery Ventilator ERV only necessary in a new home or is it needed in an existing home too? An ERV can be installed in any home and become an integral part of the heating and air conditioning system.
Your heating and cooling contractor can furnish specific details regarding your home and what type of ventilation system it requires. Please use our locator to find a local Healthy Air Pro. An ERV constantly removes polluted indoor air, carrying airborne viruses, odors, radon, tobacco smoke, nitrogen dioxides, CO, CO2 and TVOCs and replaces it with fresh outside air to provide a healthier indoor environment.
The Aprilaire Energy Recovery Ventilator has a 5-year limited warranty on parts including the core from the date of installation. What is the required maintenance of the Aprilaire model Energy Recovery Ventilator?
The Aprilaire Energy Recovery Ventilator uses indoor conditioned air to pre-heat or pre-cool the incoming outside air, depending on the season. During the winter season the cross-flow design of the EnergyMax transfer core allows the incoming outside air to be pre-heated by the warm stale indoor air being exhausted from the home. This process reduces the energy required by the heating system to warm the incoming air.
In the summer season, outside air is pre-cooled by the stale indoor air being exhausted from the home. Since the outside air is warmer than the inside air, it is cooled even though the inside air may also be warm. The Aprilaire Energy Recovery Ventilator primary function is to remove stale polluted air from your home. It may remove moisture as it transfers the temperature from the outgoing air to the incoming air. If you have moisture issues in your home, we would suggest an Aprilaire whole house dehumidifier.
What's the difference between the Aprilaire , and series air cleaners? The series models , and includes a MERV 11 filter. The model series models , and and series models , and include a MERV 13 filter. Event based control allows for operation of the HVAC systems fan for a specific schedule to allow consumers to control when the air in their home is being cleaned. The Aprilaire Energy Recovery Ventilator is designed for continuous operation.
When properly balanced by your installer, it will provide a constant supply of fresh outside air, tailored to your home's specific needs. The model Aprilaire Energy Recovery Ventilator could also be controlled by a thermostat with Ventilation IAQ logic, such as the , W, , W, W or the X ventilation controller, allowing ventilation to occur on a schedule. This option can be used when the ERV is set to provide more fresh air than required, so the run time can be reduced.
You can keep your windows closed and operate the ERV constantly all year while efficiently producing a fresh and secure environment. The Aprilaire Ventilation Control System has a 5-year limited warranty on parts from the date of installation. The Aprilaire Ventilation Control System will bring outside air into your home to reduce the stale indoor air in your home. The actual rate of ventilation required is determined by the size of your home and the number of occupants.
This ensures the optimal amount of ventilation will be provided so as not to over or under ventilate your home. This allows the control to always know the outdoor temperature so it will not open the damper if the outside temperature is too hot or cold. The Aprilaire Ventilation Control System requires minimal maintenance.
The intake duct includes a vent hood located on the outside of the home which typically includes a screen in the vent hood. This intake vent hood should be inspected regularly as the ventilation control will not perform properly if the intake vent screen is clogged with debris.
