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
Range:
-15°F/-26°C
to
120°F/49°C
adjustable in 5F°/5C°
increments
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
Range:
-40°F/-40°C
to
95°F/35°C
adjustable in 5F°/5C° increments
Aux cont
Energizes peripheral devices
(lighting equipment, exhaust fans,
and economizers).
Default:
n.o.
(n.c.):
Contact open = Occupied; contact closed = Unoccupied.
(n.o.):
Contact closed = Occupied; contact open = Unoccupied.
The contact toggles with the internal Occupied/Unoccupied
schedule (or the NSB contact on one of the digital inputs, if used).
Chngstpt
Sets the economizer changeover
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
Range:
14.0°F/-10.0°C
to
70.0°F/21.0°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%.
