Digital Heat/Cool Thermostat
(refer to Figure 1)
The LCD (Liquid Crystal Display) normally shows: the room temperature, the current mode of operation, if the Day or Night temperature setting is being used, and if the system fan is set for continuous operation.
Temperature Display
Room temperature can be displayed in either degrees Fahrenheit or degrees Celsius. If the displayed temperature seems abnormally high or low (for example: 70˚F is equal to 21˚C), press the DECREASE
Mode Button
Three modes of operation are available for all the Heat/Cool thermostat models: Heat, Cool, and Off. Additionally, with the Models 8534 and 8538, “AUtO” mode is available. The mode of operation indicates how you want your heating and cooling equipment to operate. Press the MODE button until the desired mode of operation shows on the display.
Temperature Settings – Day/Night Button
The thermostat stores four temperature settings in its memory, two for heating and two for cooling. The two temperatures for each mode are called the Day setting ”
Fan Button
The system fan will operate automatically during a heating or cooling cycle. If it is desired to run the fan continuously, press the FAN button, and a Fan “
Outdoor Button
This button will be made functional when the optional Aprilaire Model 8041 Remote Outdoor Sensor has been installed. It can then be used to find out the outdoor temperature from indoors. If the Model 8041Remote Outdoor Sensor has not been installed, two dashes “– –” will appear on the display when this button is pushed.
To ensure accurate temperature control, observe the following simple guidelines:
If tampering with the thermostat is expected and unwanted, the keypad can be locked by changing the position of the Keypad Lock DIP switch (switch no. 2) from the factory set OFF position to ON. The DIP switches are located inside the thermostat on the circuit board. To access the DIP switches, refer to the Installation Instructions that came with the thermostat, or consult your contractor. In the locked position, only the following functions can be done:
This thermostat does not require a battery. If the power goes out, the display is blank. During the period that the power is off, the heating/cooling system will not operate. When the power is restored, the thermostat will default to the Day setting and the current mode of operation at the time of the power outage.
This thermostat is equipped with a continuous memory feature which does not require any battery. The thermostat will never lose the four programmed temperature settings regardless of the length of the power outage.
Cleaning
If the surface of the thermostat becomes dirty it can be cleaned with plain water or many non-abrasive household cleaners, such as glass cleaner. When using any cleaner be careful not to get any into the interior of the thermostat. Do not spray any cleaner directly onto the thermostat. Spray the cleaner onto a soft cloth and wipe the surface of the thermostat.
