TEMPERATURE CONTROL

•Reading the Actual Room Temperature: The Model 8552 normally displays the room temperature, not the set-point temperature.

•Check the Set-Point Temperature: Press and release the DECREASE button or INCREASE button. The thermostat will display the programmed set-point temperature and a thermometer for

5 seconds before automatically returning to the actual room temperature display.

•Temporarily Override the Set Temperature: Press and hold the DECREASE button or

INCREASE button to change the room set-point temperature in 1 degree increments. The new set-point temperature will be held for 3 hours, then the thermostat will automatically

return to the program.

•Hold a New Temperature Set Point: Press and hold the DECREASE button or INCREASE button to change the room set-point temperature in 1 degree steps. The new set-point temperature

can be maintained indefinitely by pressing and releasing the HOLD button. The word “HOLD” will be displayed. The thermostat will maintain this new set-point temperature until the RESUME button is pressed returning the thermostat to the original program. This procedure is typically used during

extended vacant periods (vacations, business trips, etc.), to hold an economical set point until you return.
