Fan Status Displayed on Main Screen If the fan program is scheduled, the scheduled mode (AUTO or ON) appears.
Replacing Batteries Not all thermostat models require batteries. If the thermostat has batteries, a low battery warning flashes on the main screen for approximately 30 days. NOTES: — — If batteries are not replaced when the Low Battery warning is flashing, the LO batt screen displays continuously and the thermostat stops operating until batteries are replaced. The thermostat has a low battery indicator. However, it is M22755 recommended that you replace the batteries once each year.
Replace the batteries as follows: 1. Remove the thermostat from the base by pulling it straight out. 2. Install three new AAA alkaline batteries with proper polarization. — Always use AAA alkaline batteries. All programming (Schedule, Date and Time) information is retained during battery replacement.
3. 4. Place the thermostat back on its base by aligning the terminal screw blocks with the pins on the back of the thermostat. Push the thermostat straight onto the base.
Cleaning Thermostat Screen The thermostat has a touch screen interface. Follow these steps to clean the screen without making thermostat changes: 1. Press SCREEN. Thermostat locks out the keypad for 30 seconds to allow for cleaning. IMPORTANT Do not spray any liquid directly on the screen. If using household glass cleaner, spray cleaner on cloth. Then use the cloth wipe the screen clean. 2. 3. 4. OK TO CLEAN Use damp cloth slightly moistened with water or household glass cleaner to clean the screen.
Reading Remote Indoor Temperature If connected to an installed remote indoor temperature sensor, the thermostat displays the indoor temperature from the remote sensor(s). 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.
Screen Locked Portions of the touch screen interface can be fully or partially locked. See the Advanced Settings section for information to use these features. When the thermostat displays SCREEN LOCKED, the touch screen interface is either fully or partially locked. TUE FAN SCREEN LOCKED Inside Set AUTO SYSTEM Following Schedule HEAT Fully Locked Screen In this mode, the entire interface is locked and not functional. To unlock screen, see the Advanced Settings section.
PARTIAL LOCKOUT 1 This mode locks all keys except HOLIDAY, OVERRIDE, and temperature Up/Down arrows: — User can change the temperature setpoint, but cannot change schedule settings. — The temporary temperature change lasts until next scheduled period. The screen displays that time. — User can change the temperature setpoint, but cannot change schedule settings. — Pressing HOLIDAY sets the temperature to the Unoccupied setting for the selected period of time.
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 FAN Inside Set AUTO Following Schedule SYSTEM Recovery Simply set the program schedule to the desired time to have the space at comfort temperature.
Setting Calendar This thermostat is designed to, under normal use, automatically keep current time and day in memory for up to ten years once the calendar is set. There are two ways to set the calendar for this thermostat: SETTING CALENDAR AFTER THERMOSTAT IS ALREADY FUNCTIONING See steps 1 through 4, in the Advanced Settings section, to set year, month and day. SETTING CALENDAR WHEN THERMOSTAT IS FIRST POWERED When first powered, the thermostat proceeds through a sequence of screens to set the calendar.
