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 
thermostat controller is in the 
Unoccupied mode and a Schedule 
Override Function is enabled using 
either the Main User Menu or BI1, or 
BI2 is configured as a temporary 
override remote contact (RemOVR).
Sets the effective duration of the 
Temporary heating or cooling 
setpoints using the 

UP/DOWN

 

arrow keys.
Default: 

2.0 hrs

Range: 

0.0 to 24.0 hrs

 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)

Cal RH

Sets the desired humidity sensor 
calibration (offset). The offset can 
be added to or subtracted from the 
actual displayed room humidity 
(TEC2236-4, TEC2236H-4, 
TEC2236H-4+PIR, TEC2256-4, 
TEC2256H-4, and 
TEC2256H-4+PIR models). This 
parameter can be used only if the 
dehumidification sequence is 
enabled.
Default: 

0% RH

 Range:

 -15.0% RH

 to 

15.0% RH

 (adjustable in 1% RH increments)
