SETTING FAN Fan selections vary based on the HVAC system type. ON—fan runs continuously. Use this setting for improved air circulation or for more efficient central air cleaning. AUTO—fan is controlled by the system. Typically, the fan runs only during cooling or heating operation. Setting Temperature Overrides There are three temperature override options: — Hold Temperature Until — Override, and — Holiday.
NOTE: The ability to change settings remains for approximately seven seconds. Once neither the temperature nor the time continue to flash, you must restart at step 1 to make changes. 4. Use the Up and Down keys to set the desired time for the thermostat to resume the programmed schedule. Tue Hold Until NOTE: The installer setup can limit the length of time for an override to 1, 2, 3, or 4 hours beyond the current time. 5.

Replacing Batteries With proper power and connections, the thermostat does not require batteries. Thermostats with batteries provide a warning when the batteries run low. This warning flashes on the main screen for approximately 30 days. NOTES: — — If batteries are not replaced when Low Battery warning is flashing, the LO batt screen displays continuously and M22383 thermostat stops operating until batteries are replaced.
Replace the batteries as follows: 1. Remove the thermostat from the base by pulling it straight out. 2. Install two new AA alkaline batteries with proper polarization. NOTES: — — WALL Always use AA alkaline batteries. All programming (Schedule, Date and Time) information is retained during battery replacement.
3. Place the thermostat back on its base: a. Align the terminal screw blocks with the pins on the back of the thermostat. b. Push the thermostat straight onto the base. NOTES: — — BATTERIES (2) After two minutes, the device automatically returns to the main screen. To return to the main screen before the two minutes pass, press a key.
Reading Remote Indoor Temperature If connected to an installed remote indoor temperature sensor, the thermostat displays the indoor temperature from the remote sensor(s). REMOTE INDOOR TEMPERATURE READING NOTE: When connected to an installed remote indoor temperature sensor, the thermostat internal sensor is not used.
Reading Outdoor Temperature If connected to an outdoor sensor, the thermostat displays the Outside temperature. VIEW OUTSIDE TEMPERATURE The Outside temperature is located in the lower right corner of the main screen. If it is not on the main screen, view the outdoor temperature by pressing MORE until the outside temperature shows.
Keys Locked Some key control can be fully or partially locked. When the thermostat displays “Locked”, key control is either fully or partially locked.

See the Setting Temperature Overrides section for details. PARTIAL LOCKOUT 2 This mode locks all keys except HOLIDAY and OVERRIDE: — Selecting HOLIDAY sets the temperature to the Unoccupied setting. The temperature setting cannot be changed. The number of days to hold the holiday can be changed.
Temperature Recovery The thermostat is equipped with a feature to eliminate guesswork when setting a schedule. That is, the user need not know the amount of time for the HVAC system to bring the space to temperature (without overshoot) prior to the scheduled time.The thermostat manages that automatically. Tue PM Recovery System Auto Fan Auto System & Fan Override Occupied More Simply program the desired time to have space at comfort temperature.
Setting Calendar This thermostat is designed to, under normal use, automatically keep the current time and day in the memory for up to ten years once the calendar is set.
