Controllers Installation Instructions

11

H stage

Reverts the operation of a two-stage 
thermostat controller to a single-
stage thermostat controller when 
the second heating stage is not 
needed.
Default: 

2.0

(1.0):

 One Stage

(2.0):

 Two Stages

C stage

Reverts the operation of a two-stage 
thermostat controller to a 
single-stage thermostat controller 
when the second cooling stage is 
not needed.
Default: 

2.0

(1.0):

 One Stage

(2.0):

 Two Stages

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.
Default: 

-40°F/-40°C

Range: 

-40°F/-40°C

 to 

95°F/35°C

 adjustable in 5F°/5C° increments

Unocc TM

Sets the time delay between the 
moment when the thermostat 
controller toggles from the Occupied 
mode to the Unoccupied mode after 
the last motion is detected by the 
occupancy sensor.
Default: 

0.5 hours

Range: 

0.5 hours

 to 

24.0 hours

 adjustable in 0.5 hour 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

2

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
