Control Installation Instructions

14

Set type

Provides the option of temporarily 
changing the heating or cooling 
setpoint by pressing the 

UP/DOWN

arrow keys.

Default: 

permnent

(temporar):

 Local changes to the heating or cooling setpoints are 

temporary, and remain effective for the specified TOccTime.

(permnent):

 Local changes to the heating or cooling setpoints are 

permanently stored in the thermostat controller memory.

Spt Func

Determines the operation and 
usage of the local setpoint interface 
by the user.
Default: 

Dual Stp

(Attch Stp):

 Single Occupied Setpoint Adjustment. The displayed 

setpoint is the setpoint from the last action taken by the thermostat 
controller, or the setpoint currently in use. Both the heating and 
cooling setpoints are changed simultaneously, while respecting the 
minimum configured deadband. If one setpoint is desired over the 
other, use the 

MODE

 key to toggle between the two setpoints.

(Dual Stp):

 Dual Occupied Setpoint Adjustment. The displayed 

setpoint is the setpoint from the last action taken by the thermostat 
controller, or the setpoint currently in use. The heating and cooling 
setpoints can be separated individually, allowing the minimum 
configured deadband to expand. If one setpoint is desired over the 
other, use the 

MODE

 key to toggle between the two setpoints.

TOccTime

Sets the duration of the Temporary 
Occupancy Time when the heating 
or cooling setpoints in the Occupied 
mode are established by:
• 

an Override Function enabled in 
the Main User Menu (when the 
thermostat controller is in the 
Unoccupied mode)

• 

a temporary heating or cooling 
setpoint

Default: 

2.0 hrs

Range: 

0.0 

to

 24.0 hrs

 (adjustable in 1-hour increments)

Deadband

Sets the minimum deadband 
between the heating and cooling 
setpoints.
Default: 

2.0F°/1.0C°

Range: 

2.0F°/1.0C° 

to

 5.0F°/2.5C°

 (adjustable in 1.0F°/0.5C° 

increments)

Cal RS

Sets the desired room air sensor 
calibration (offset). The offset can 
be added to or subtracted from the 
actual displayed room temperature.
Default: 

0.0F°/0.0C°

Range: 

-5.0F°/-2.5C° 

to

 5.0F°/2.5C°

 (adjustable in 1.0F°/0.5C° 

increments)
