OPERATION
Mode —
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 ther-
mostat will only enter Heating mode (if the room tempera-
ture is below the heating set point). If COOL is selected, the
thermostat will only enter Cooling mode (if the room tem-
perature 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.
Two-Stage Operation —
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.
Electric Heat —
When the Electric Heat option in the
advanced set up is set to ON, the thermostat will turn on the
fan immediately any time there is a heat demand. This fea-
ture should only be used on electric heating applications. Do
not use with gas heat.
The second stage of heat or
Dry Contact Switch/External Device —
tact switch is provided to allow an external device to force
the thermostat into Unoccupied mode. When the thermostat
is forced into Unoccupied mode via the dry contact closure,
the Unoccupied mode icon will blink each second.
SOFT START — When multiple thermostats are controlled
by the same external device, a Soft Start option can be used
to stagger the turn on times of the HVAC equipment. This
feature may cause a delay in operation after entering or leav-
ing Unoccupied mode.
Remote Temperature Sensor —
ture sensor is available to read the temperature from a space.
If a remote temperature sensor is connected, the thermostat
will ignore the reading of its internal sensor. When the ther-
mostat is using a reading from a remote sensor, the degree
symbol above the temperature reading will blink.
Outdoor Temperature Sensor —
perature sensor may be provided to read the outside tem-
perature. Outside temperature can be viewed by pressing and
holding the Mode button for 2 seconds.
