NOTE: The cooling temperature set point must be higher than the heating temperature set point. (The temperature difference may be changed in the advanced setup con®guration.)
OPERATION
The Mode button selects the operating mode of the thermo- stat. If OFF is selected, the thermostat will not enter Heat- ing or Cooling mode. If HEAT is selected, the thermostat will only enter Heating mode (if the room temperature is below the heating 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.
I. AUTO-CHANGEOVER
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 ther- mostat will automatically switch to maintain the desired tem- perature setting. The thermostat does not need to be manu- ally changed from heating to cooling or cooling to heating operation.
II. LIGHT-ACTIVATED OPERATION
A light sensor is provided on the thermostat for light activa- tion. The thermostat must be in Program On mode for light activation to be initiated. When the sensor detects light (the space is occupied), the thermostat will enter Occupied 1 mode and heat or cool according to the Occupied 1 set points. If the room is dark, the thermostat will follow its programmed schedule.
NOTE: Light activation does not work in Holiday mode.
III. TWO-STAGE OPERATION
The second stage of heat or cool is turned on when the ®rst stage has been on for a minimum of 2 minutes and the tem- perature differential from the set point is equal to or greater than the set point plus the deadband plus 2 degrees.
IV. CLOCK BACKUP
In the event of a power loss, the thermostat will keep time for a minimum of 48 hours without external power or batteries.
V. FAN OPERATION
If Fan On is selected, the fan will run continuously during occupied schedule (except when Mode is switched to OFF).
The fan will be off during unoccupied schedule except during heating or cooling operation.
If Fan On is not selected, the fan will only operate during heating or cooling operation.
VI. EMERGENCY HEAT
Emergency heat is available for heat pump applications. To turn on emergency heat, press and hold the Fan button. While holding the Fan button, press the UP button for 2 seconds. An ``EH'' will be displayed. During emergency heat, the fan will operate and the second stage of heat will be energized (locking out the ®rst stage compressor). To exit emergency heat, press and hold the Fan button. While holding the Fan button, press the UP button for 2 seconds. During emergency heat, only OFF and HEAT modes are available.
VII. ELECTRIC HEAT
When the Electric Heat option in the advanced setup is set to ON (con®gured by installer), the thermostat will turn on the fan immediately any time there is a heat demand. This feature should only be used on electric heating applications. Do not use with gas heat.
VIII. HOLIDAY MODE
When the thermostat is in Holiday mode, the thermostat will operate under Unoccupied set points. To con®gure and acti- vate the Holiday mode, press the Holiday button. The ``HOL'' icon will be displayed along with the remaining days of Holi- day mode operation. Press the UP or DOWN ARROWS to se- lect the number of days that the holiday schedule will be in effect. A value of 0 disables Holiday mode. The duration can be set from 1 to 99 days. The thermostat will enter Holiday mode on midnight of the next day after the mode has been activated. Holiday mode will remain in effect until midnight of the last con®gured day.
If the Holiday mode is in effect, the number of days remain- ing will blink on and off and the ``Unoccupied'' icon will be displayed. The Override button will be active during Holiday mode. The Dry Contact Switch is ignored.
To turn off the Holiday mode before the remaining con®g- ured days have passed, press the Holiday button to enter into the Con®guration mode. Press the DOWN ARROW to set the number of days to zero. Holiday mode will be disabled.
