Cooling
The thermostat's application and configuration determine the specific cooling sequence. It can control up to 2
stages of cooling, with an additional output for a reversing valve, for non-Carrier heat pump applications, or up to
3 stages of cooling for non-heat pump applications.
NOTE
The cooling stages are controlled based on a drift algorithm and the configurable
DIFFERENTIAL
value
(.5°F default)
The following conditions must be true for the cooling to operate:
•
The OAT must be above the
COOL LOCKOUT
(55°F default), if enabled
•
The cooling stage 5-minute minimum off-timer has expired
•
The space temperature has exceeded the cooling setpoint by the
DIFFERENTIAL
value (.5°F default)
Additional stages are added and dropped, based on demand using the
DIFFERENTIAL
value,
STAGE DELAY
timer,
and
FORCED STAGE UP
timer configuration values. If the
LOW COOL LOCKOUT
is configured for
ON
, or between
80°F and 110°F, and the OAT is equal to or greater than that value, cool stages 1 and 2 are energized on a
demand for cooling and remain on until the cooling demand is satisfied.
NOTE
Once a cooling stage is energized, it remains on for a minimum of 5 minutes, regardless of demand.
Econ enable
The thermostat's application and configuration determine the specific economizer enable sequence. You can
enable an output relay in OCCUPANCY OUTPUT. The output is ON whenever the thermostat is Occupied and OFF
when Unoccupied.
NOTE
The relay options may be limited by other programming options such as Humidity control, Heat Pump, etc..
The status of the economizer may be monitored using a dry contact (N.O.) on the
Remote Sensor Input
.
