perature set point. The thermostat will turn on heating or cool-
ing to meet the heating or cooling temperature set point.
If the thermostat is in AUTO mode, pressing the UP AR-
ROW or DOWN ARROW buttons will adjust both the heat-
ing and cooling set points.
Pressing the UP ARROW or DOWN ARROW buttons in

The UP ARROW and DOWN ARROW buttons are also

MODE BUTTON — The Mode button selects the operating
mode of the thermostat.
• If OFF is selected, the thermostat will not enter Heating or
Cooling mode.
• If HEAT is selected, the thermostat will only enter Heat-
ing mode (if the room temperature is below the heating set
point). The thermostat will not provide cooling.
• If COOL is selected, the thermostat will only enter Cool-
ing mode (if the room temperature is above the cooling set
point). The thermostat will not provide heating.
• If AUTO is selected, the thermostat will enter Heating or
Cooling mode based on the room temperature and the heat-
ing and cooling set points. The thermostat will provide au-
tomatic changeover from Heating to Cooling mode and
Cooling to Heating mode when required. The thermostat
will automatically switch to maintain the desired tempera-
ture setting. The thermostat does not need to be manually
changed from heating to cooling or cooling to heating
operation.
• If PROGRAM ON is selected, your daily schedule is en-
abled and the thermostat will follow the programmed daily
schedule stored in its memory.
NOTE: Only the transmitter with Unit ID Number 1 may
have a programmed schedule.

ternate on the thermostat display.
The set points are adjustable with the UP ARROW and
DOWN ARROW keys during Override mode.

ride button is pressed, the thermostat will go into Unoccu-
pied mode immediately. The thermostat will remain in Un-
