HUMIDIFIER
— The 6th output relay that enables a field-installed humidifier. The
humidifier is on if there is humidity demand and any heating equipment is on. If set to
YES
, the thermostat cannot be configured as the 3rd stage compressor, Humidi-MiZer™,
Dehumidification, or HP reversing valve operation.

NO
YES/NO
DEHUMIDIFIER
— Sets the 6th output relay to enable a factory-installed Humidi-MiZer™
for dehumidification or to use the first stage of cooling.
•
If YES, the 6th relay energizes the Humidi-MiZer™ on the Carrier unit.
•
If OVRCL(2), it uses the first stage of cooling to satisfy a dehumidification demand,
but will not overcool the space by more than 2°F.
•
If YES, the thermostat cannot be configured for 3rd stage compressor, humidifier, or
HP reversing valve operation.

MAX HEAT SETPOINT
— The maximum heating setpoint available on the Heat Setpoint
Wheel and the maximum heating setpoint that can be used during the occupied program
schedule.
D:
R:
88°F
50°F to 88°F
MIN COOL SETPOINT
— The minimum cooling setpoint that is available on the Cool
Setpoint Wheel and the minimum cooling setpoint that can be used during the occupied
program schedule.
D:
R:
52°F
52°F to 90°F
AUX HEAT LOCKOUT
— The outdoor temperature value that lockouts the auxiliary heat. If
the
AUX HEAT LOCKOUT
temperature setting is not
OFF
, and the outdoor air temperature
is greater than
AUX HEAT LOCKOUT
value, then the
Aux Heat
(W1 and W2) outputs are
not energized. Once the output is energized, it remains energized until the demand
algorithm no longer requires the capacity of the auxiliary heat, regardless of the value of
the outdoor air temperature.
NOTE
If the
MODE
is emergency heat (
E-HEAT
), the auxiliary heat is allowed to be
energized regardless of the outdoor temperature.

HP LOCKOUT
— If you select
OFF
, the heating equipment cycle always starts with the heat
pump, regardless of the outdoor air temperature.
•
If you select a lockout temperature and the outdoor air temperature is less than the
selected temperature, the heating cycle is started with the
AUX HEAT
source.
•
If the outdoor air temperature is equal to or greater than the selected temperature,
the heating cycle is started with the heat pump.
•
If the outdoor temperature is not available, all heating cycles start with compressor
heat. Once the heat pump is energized, it remains energized until the heating
demand no longer requires heat pump heating, regardless of the outdoor air
temperature.
•
When the heat pump is not energized, but there is sufficient demand to request heat
pump heating, the heat pump lockout temperature is checked against the outdoor
air temperature, and if the outdoor air temperature is greater than the heat pump
lockout temperature, the heat pump is energized.
