ENERGYSTAR® PROGRAM INFORMATION (Programmable Models Only)
About half of all energy used by households goes to heating and cooling the home. If you’ve selected a programmable Aprilaire® Electronic Thermostat, you have made a significant step toward conserving energy usage and costs, while improving your indoor comfort.
In fact, the Aprilaire Electronic Thermostat Models 8363, 8365 & 8366 have earned the “ENERGYSTAR®” designation of the U. S. Environmental Protection Agency (EPA). This means that your Aprilaire Thermostat is a highly efficient, cutting-edge product that is good for the environment. It saves energy and costs less to operate than similar products that do not qualify for the ENERGY STAR label. ENERGY STAR products help you differentiate between standard efficiency and high-efficiency products. By using ENERGY STAR products, you are helping to prevent air pollution while saving money on your utility bills.
According to the EPA, taking advantage of the times that a home is unoccupied or the occupants are asleep, an ENERGY STAR thermostat can reduce heating and cooling bills by as much as 30%. The Aprilaire Thermostat has programmable capabilities that allow you full flexibility to set your heating and cooling systems to meet your comfort and energy needs. As an ENERGY STAR partner, Aprilaire has determined that this product meets the ENERGY STAR guidelines for energy efficiency.
See Figure 1 for a description of the thermostat and controls.
See Figure 2 for the display.
Your thermostat has three operating modes, COOL, OFF and HEAT. Heat pump Models 8346 & 8365 have an additional EMERGENCY HEAT mode (E-HEAT on display).
COOL
In the COOL mode, the thermostat will control the cooling system and maintain your cooling set point.
NOTE:
There is a 4-minute delay after a cooling call is completed. This is to protect the equipment’s compressor from short cycling.
OFF
In the OFF mode, the thermostat will not operate the heating or cooling equipment. The FAN switch can be placed in the ON position to operate the fan continuously.
CAUTION: Do not set to OFF mode during periods when freezing temperatures may occur.
HEAT
In HEAT mode, the thermostat will control the heating system.
NOTE:
There is a 4-minute delay after a heating call is completed on heat pump models 8346 & 8365. This is to protect the equipment’s compressor from short cycling.
E-HEAT (MODELS 8346 & 8365 ONLY)
In E-HEAT mode, the thermostat will activate the emergency heat with any heat call. (Note-the AUX light in the upper left-hand corner of the thermostat will illuminate any time there is a call for Emergency Heat or Auxiliary Heat.)
TEMPORARILY RAISE AND LOWER TEMPERATURE – MODELS 8344, 8346 & 8348
TEMPORARILY RAISE AND LOWER TEMPERATURE -MODELS 8363, 8365 & 8366
The thermostat has two settings for fan operation, AUTO and ON.
AUTO
In the AUTO setting, the fan operates only when the heating or cooling equipment is on.
ON
In the ON setting, the fan will operate continuously.

PROGRAM FOR HEATING AND COOLING
As part of the ENERGYSTAR program, your thermostat has been pre-programmed with the following times and temperatures, which can be modified as desired.
ENERGYSTAR SETTINGS | |||
Event | Temperature Setting | Time Schedule | |
Weekday | Weekend | ||
Wake | Heat = 70°F Cool = 78°F | 6:00 AM | 6:00 AM |
Leave | Heat = 62°F Cool = 85°F | 8:00 AM | 8:00 AM |
Return | Heat = 70°F Cool = 78°F | 5:00 PM | 5:00 PM |
Sleep | Heat = 62°F Cool = 82°F | 10:00 PM | 10:00 PM |
PROGRAM EVENTS
Your thermostat has 5/2 (5 weekdays and 2 weekend days) programming functionality, which allows the user to set four events for the weekdays (Monday through Friday) and two or four events for the weekend (Saturday and Sunday). The events are WAKE, LEAVE, RETURN and SLEEP. If you are normally home on the weekend, you can set up your thermostat to use only 2 events (WAKE and SLEEP) on Saturday and Sunday.
WAKE is the time and temperature setting you desire when you wake in the morning. The event should include extra time for the heating and cooling equipment to heat or cool the house to a comfort level prior to getting out of bed.
NOTE:
It will take some time for your heating or cooling system to reach the desired temperature when returning from the setback. Therefore, it is suggested you set your program time before the actual time you want your home to reach the desired temperature. For example, if you get up at 7:00 AM and have a 6-degree setback, set your WAKE event to 6:00 AM to be sure the desired temperature is reached by 7:00 AM.

WAKE – WEEKDAY
TO CHANGE THE COOLING PROGRAM
HOLD TEMPERATURE / VACATION – MODELS 8363, 8365 & 8366
When the thermostat is in HOLD the set point will be maintained until the HOLD/Resume button is pressed.
NOTE:
New batteries must be replaced within one minute after the removal of old batteries. If more than one minute elapses the programmed settings will be lost and revert to the factory settings. See Figures 3 and 4 for cover removal and battery orientation.
Replace batteries once per year or when “LOW BATTERY” appears on the display. This will keep the thermostat working properly. Replace with two new AA alkaline batteries.
If the surface of the thermostat becomes dirty it can be cleaned with plain water or a non-abrasive household cleaner including glass cleaner. When using any cleaner, be careful not to get any into the interior of the thermostat. Do not spray any liquid directly onto the thermostat. Spray the cleaner on to a soft cloth and wipe the surface of the thermostat.
TO CLEAR THE “CHANGE WATER PANEL” OR “CHANGE FILTER” INDICATOR
Your thermostat is equipped with indicators on the display to notify you when it is necessary to change the systems filter and humidifier Water Panel.
TO CHANGE °F TO °C
The Aprilaire Thermostat is capable of displaying temperatures in Fahrenheit or Celsius.
TO CHANGE DIFFERENTIAL SETTING (d1)
The Aprilaire Thermostat is capable of adjusting the differential to change how often the heating and cooling equipment will cycle on and off.
TO CHANGE SECOND STAGE DIFFERENTIAL SETTING (d2)(MODELS 8348 & 8366 ONLY)
This setting controls how far from the first stage differential setting the temperature will be allowed to fall/rise before initiating the second stage.
TO CHANGE THE TEMPERATURE OFFSET
Aprilaire thermostats are factory tested and calibrated within 1° Fahrenheit. However, it may be desirable to adjust the reading of the thermostat to coincide with other temperature-measuring devices.
TO CHANGE THE WATER PANEL INDICATOR SETTING
The Aprilaire Thermostat is capable of indicating when the Water Panel of a humidifier should be changed.
TO SET THE HUMIDIFIER TYPE
NOTE:
This feature will only be displayed if the Water Panel Change value is not set to “OFF”.
TO CHANGE THE AIR FILTER INDICATOR SETTING
The Aprilaire Thermostat is capable of indicating when the air filter should be changed.
TABLE 1 | ||
FILTER TYPE | CHANGE FREQUENCY | THERMOSTAT SETTING |
Disable the feature | OFF | |
Disposable Panel | 1 month | 1 |
Washable Electrostatic | 3 months | 3 |
Extended Media (Aprilaire) | 6-12 months | 6 or 12 |
TO SET THE NUMBER OF WEEKEND EVENTS (MODELS 8363, 8365, AND 8366 ONLY)
Use this feature to set the number of events for the weekend program. The default value is 4 events (The ENERGYSTAR® setting), which will result in the “LEAVE” and “RETURN” events to be used during programmed operation. If your schedule is such that the home or building is generally occupied during the weekends, switch to 2 events on the weekend. This will cause the “LEAVE” and “RETURN” events to be ignored during programmed operation.
