Thermostat Front Panel Buttons | Carrier 33CS specification

Thermostat Front Panel Buttons Ð The thermo- stat has buttons on the front cover which are used to raise or lower the desired set point and override the current program. See Fig. 2.

SET POINT BUTTONS Ð The UP ARROW and DOWN ARROW buttons will raise or lower the current desired tem- perature set point. If the thermostat is in AUTO mode, press- ing the UP ARROW or DOWN ARROW buttons will adjust both the heating heating and cooling set points. Pressing the UP ARROW or DOWN ARROW buttons in Cooling mode will adjust only the cooling set points. Pressing the UP ARROW or DOWN ARROW buttons in Heating mode will adjust only the heating set points. The UP ARROW and DOWN ARROW buttons are also used in Programming mode.

OVERRIDE BUTTON Ð The Override button is used to force the thermostat from Unoccupied mode into the Occu- pied 1 mode comfort settings. The Override period will be set at 30 minutes. The thermostat will then return to Unoc- cupied mode. To increase the amount of time in Override mode, press the Override button again. Thirty minutes of over- ride time will be added for each time the Override button is pressed up to a maximum of 4 hours. After the 4-hour limit has been reached, press the Override button again to cancel override mode.

While in Override mode, the Override icon and the Occupied 1 icon will be displayed on the thermostat. The time of day and the minutes remaining in Override mode will alternate on the thermostat display.

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

NOTE: If the thermostat is in Occupied mode and the Over- ride button is pressed, the thermostat will go into Unoc- cupied mode immediately. The thermostat will remain in Unoccupied mode until the next Occupied start time.

Thermostat Programming Buttons Ð The ther- mostat has programming buttons which are used to change the set points of the thermostat, set the modes, and program schedules. The programming buttons are accessible from underneath the thermostat cover. To access the program- ming buttons, pull on the hinged thermostat cover. See Fig. 3. The programming buttons are: Mode, Fan, Holiday, Program, and Set Clock.

The UP ARROW and DOWN ARROW buttons are used to scroll through programming set points. The buttons are also used to answer yes or no.

KEYPAD LOCK Ð The thermostat has a keypad lockout feature which will not acknowledge front panel buttons until the lockout sequence is entered. To disable or lock the key- pad, press and hold the Mode button. While holding down the Mode button, press the UP and DOWN ARROW buttons simultaneously. The ``Locked''' icon will appear on the display.

The thermostat is unlocked by performing the same pro- cedure. Press and hold the Mode button. While holding down the Mode button, press the Up and Down Arrow buttons simultaneously. The ``Locked''icon will be removed from the display.

FAN BUTTON OPERATION Ð The Fan button selects fan operation. When the fan is set to FAN ON, the fan will run continuously for improved air circulation.

NOTE: When the thermostat is in Unoccupied mode, the fan will run only during heating or cooling operation, even if the fan is set to FAN ON; this is the energy-saving smart fan feature.

When the fan is not set to FAN ON (no icon displayed on thermostat screen), the fan will run during heating and cool- ing operation only.

MODE BUTTON OPERATION Ð 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 Heating mode (if the room temperature is below the heat- ing set point). If COOL is selected, the thermostat will only enter Cooling mode (if the room temperature is above the cooling set point). If AUTO is selected, the thermostat will enter Heating or Cooling mode based on the room tempera- ture and the heating and cooling set points. If PROGRAM ON is selected, the stored schedule is enabled and the ther- mostat will follow the Occupied and Unoccupied schedules stored in its memory.

Auto-Changeover Ð When the thermostat mode is set to AUTO, the thermostat will provide automatic changeover from Heating to Cooling mode and Cooling to Heating mode when required. The thermostat will automatically switch to maintain the desired temperature setting. The thermostat does not need to be manually changed from heating to cooling or cooling to heating operation.

HOLIDAY MODE Ð The Holiday button places the ther- mostat into Holiday mode. During Holiday mode, the un- occupied set points are enforced. The number of days the thermostat will be in Holiday mode can be set.

Set Clock Ð The Set Clock button allows the user to change the time and day displayed on the thermostat. Press the Set Clock button to enter Set Time mode. See Fig. 4. The current time will blink on and off. Press the UP ARROW and DOWN ARROW buttons until the correct time is shown. Hold down the buttons to quickly move through the time display. The AM and PM annunciators will automatically change. To scroll through by hours only, press and hold down the Fan button while pressing the UP or DOWN ARROW buttons. To ensure the schedules are properly followed, make sure that AM or PM is correct for the time chosen. When the
