H stage Reverts the operation of a two-stage
thermostat to a single-stage
thermostat when the second
heating stage is not needed.
Default: 2.0
C stage Reverts the operation of a two-stage
thermostat to a single-stage
thermostat when the second cooling
stage is not needed.
Default: 2.0
H lock Discontinues heating operation in
response to the outdoor air
temperature. Requires that an
outdoor air temperature sensor be
installed and connected.
Default: 120°F/49°C
C lock Discontinues cooling operation in
response to the outdoor air
temperature. Requires that an
outdoor air temperature sensor be
installed and connected. C lock
does not disable economizer free
cooling operation.
Default: -40°F/-40°C
Aux cont Energizes peripheral devices
(lighting equipment, exhaust fans,
and economizers).
Default: n.o.
2 Sets the economizer changeover
Chngstpt
strategy, based on the outdoor air
temperature. Requires that an
outdoor air temperature sensor be
installed and connected.
When the OA temperature is below
the changeover setpoint, free
cooling is used (economizer
operation). When the OA
temperature is above the setpoint,
mechanical cooling is used
(compressor operation).
Default: 55.0°F/13.0°C
Min pos Sets the minimum position for the
OA dampers on the economizer.
These dampers are energized to
minimum position when the fan
(Terminal G) is energized and the
thermostat is in the Occupied mode.
When the schedule is in the
Unoccupied mode, the minimum
position is 0%.
Default: 0.0%
