OPERATION
The Mode button selects the operating mode of the ther-
mostat. 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 ther-
mostat will only enter Cooling mode (if the room tempera-
ture is above the cooling set point). If AUTO is selected, the
thermostat will enter Heating or Cooling mode based on the
room temperature and the heating and cooling set points. If
PROGRAM ON is selected, the stored schedule is enabled
and the thermostat will follow the time period schedules stored
in its memory.
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 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.
Electric Heat —
When the Electric Heat DIP switch at
the receiver is set to ON, 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.
Dry Contact Switch/External Device —
A dry con-
tact switch is provided to allow an external device to force
the thermostat into Unoccupied mode.
Two-Stage Operation —
The second stage of heat or
cool is turned on when the first stage has been on for a mini-
mum of 2 minutes and the temperature differential from the
set point is equal to or greater than the set point plus the
deadband plus 2 degrees.
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 Auto is selected, the fan will only operate during heat-
ing or cooling operation.
