Table 1 — Daily Schedule Planner
NOTE: The cooling temperature set point must be higher than the heating temperature set point. (The temperature difference may be changed in
the advanced set up configuration by the installer.)
Select Desired Temperature —
The UP and DOWN
ARROW buttons are used to adjust the heating and cooling set
points. Pressing the UP and DOWN ARROW buttons in Auto
mode will adjust both the heating and cooling set points. Press-
ing the UP and DOWN ARROW buttons in either Heat or
Cool mode will adjust only the heating or cooling set point.
NOTE: If the Single Set Point mode is configured by the
installer, there will be only one set point for both heating and
cooling.
Four-Pipe Operation —
The Mode button selects the
operating mode of the thermostat. If OFF is selected, the ther-
mostat will not enter Heating or Cooling mode. If HEAT is se-
lected, 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 temperature and the heating and cooling set
points. If Program On is selected, the thermostat will follow the
occupied schedule.
Two-Pipe Operation
NOTE: The thermostat default is 4-pipe operation. The ther-
mostat must be configured for 2-pipe operation.
HEAT ONLY — When the thermostat is configured for Heat
Only operation, only Heat, Program On, and Off modes can be
selected.
COOL ONLY — When the thermostat is configured for Cool
Only operation, only Cool, Program On, and Off modes can be
selected.
HEAT/COOL WITH CHANGEOVER SENSOR — When
the thermostat is configured for operation with a changeover
sensor, all the modes are available for operation. If the water
temperature is changed during the year, the thermostat will au-
tomatically lock out the incorrect mode. Heat or Cool modes
may not be available, depending on water temperature.
TOTAL OR AUXILIARY ELECTRIC HEAT — 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 room temperature is below the heating set point). For
total electric heat, a call for heat will activate the electric heater.
For auxiliary electric heat, a call for heat will either activate the
electric heater (if chilled water is in the coil), or open the coil
valve (if hot water is in the coil).
If COOL is selected, the thermostat will only enter Cooling
mode (if room temperature is above the cooling set point and
chilled water is in the coil).
If AUTO is selected, Heating or Cooling mode based on the
room temperature and the heating and cooling set points.
NOTE: Certain modes may be locked out by the type of appli-
cation or the reading of the changeover sensor.
Auto-Changeover — When the thermostat mode is set to
AUTO, the thermostat will provide automatic changeover from
