AprilAire Thermostats & Sensors

The Auto mode enables the AprilAire Thermostat to initiate heating or cooling based on the specified heating and cooling temperature set points. As the temperature in the living space fluctuates, the thermostat assesses the heating and cooling set points to determine whether heating or cooling activation is necessary.

Whenever the living space temperature deviates from the desired level, the AprilAire Thermostat initiates a heating or cooling cycle, depending on what is required to restore the living space temperature to the desired level. This differs from the Heat or Cool mode, where the AprilAire Thermostat can only activate heating or cooling but not both. In the Heat mode, it can only initiate a heating cycle, and in the Cool mode, it can only initiate a cooling cycle. In Auto mode, it has the flexibility to initiate either a heating or cooling cycle as needed.

The AprilAire Thermostat features a mode function, and one of the available modes is "Off." When in the Off mode, the thermostat is restricted from initiating heating or cooling calls, and this setting does not impact the thermostat's programming. To activate the AprilAire Thermostat and operate the heating and cooling system, it must be set to either the Heat, Cool, On, or Auto mode.

You can activate the Vacation feature either through the AprilAire Healthy Air App or directly on the thermostat.

Creating a schedule enables you to set different temperature preferences at various times during the day, promoting energy efficiency when you're away from home. The daily schedule is divided into four segments:

Wake: Preferred temperature upon waking up
Leave: Temperature when you're not at home
Return: Preferred temperature upon returning home
Sleep: Preferred temperature during sleep


Individual start times and temperatures are customizable to suit your specific preferences and home requirements. You can change the schedule either through the thermostat or the app.

To Set Up Within the App:

1. Select the thermostat within the app
2. Towards the bottom, choose Schedule and ensure it is set to On
3. Select Schedule > Modify
4. Configure the Wake, Leave, Return, and Sleep settings, including start time, controlling sensor (if wireless sensors are installed), heat setpoint, cool setpoint, and fan control
5. Repeat these steps for each day or copy the configuration to other days

1. Navigate to Menu > Schedule
2. Turn the schedule ON by highlighting the ON/OFF toggle and pressing Select
3. Select Modify
4. The thermostat allows configuration for All Days, Weekdays, Weekends, or individual days. Choose the desired day(s)
5. Within the selected day(s), configure the Wake, Leave, Return, and Sleep settings, including start time, heat setpoint, cool setpoint, fan control, and controlling sensor (if wireless sensors are installed)
6. Repeat these steps for each day

Geofencing establishes a virtual boundary around your residence and automatically switches your thermostat to Away mode upon leaving this boundary, leading to energy savings. Upon re-entering the boundary, the thermostat returns to its regular operation, ensuring your home is at the preferred comfort level upon your arrival.

To configure Geofencing, follow these steps using the AprilAire Healthy Air App:

1. Click on the menu option located in the upper left corner.
2. Choose Geofencing from the list
3. Activate Geofence
4. Enter the address where the thermostat is placed. If you're presently at the location, you can opt for Use Current Location to save the address.
5. Specify your desired radius for the geofence (virtual perimeter), ranging from 1 mile to 25 miles. This radius determines when the thermostat switches to Away mode upon exiting the area and returns to normal upon re-entry.
