19

St-By HT

Sets Stand-by heating setpoint 
when used with occupancy sensor; 
value is between occupied and 
unoccupied heating setpoints.
Default:

 69.0°F/20.6°C

Range: 

40.0°F/4.5°C

 to 

90.0°F/32.0°C

Note:

When adjusting the 

temperature, press the 

UP/DOWN

 arrow keys to 

change the temperature in 
0.5F°/0.5C° increments; press 
and hold the 

UP/DOWN

 arrow 

keys to change the 
temperature in 5.0F°/5.0C° 
increments.

St-By CL

Sets Stand-by cooling setpoint limit 
when used with occupancy sensor; 
value is between occupied and 
unoccupied cooling setpoints.
Default: 

78.0°F/25.6°C

Range: 

54.0°F/12.0°C

 to 

100.0°F/37.5°C

Unocc HT

Sets the Unoccupied Heating 
setpoint value.
Default: 

62.0°F/16.5°C

Range: 

40.0°F/4.5°C to 

90.0°F/32.0°C

Unocc CL

Sets the Unoccupied Cooling 
setpoint value.
Default: 

80.0°F/26.5°C

Range: 

54.0°F/12.0°C to

100°F/37.5°C

Heat max

Sets the Occupied and Unoccupied 
maximum Heating setpoint values.
Default: 

90.0°F/32.0°C

Range: 

40.0°F/4.5°C to

90.0°F/32.0°C

Cool min

Sets the Occupied and Unoccupied 
minimum Cooling setpoint values.
Default: 

54.0°F/12.0°C

Range: 

54.0°F/12.0°C to

100°F/37.5°C

Pband

Proportional Band used by the PI 
temperature control loop of the 
thermostat.
Pband is not converted with C or F 
scale and is always shown with a 
range of 3 to 10.
Default: 

3

3F°/1.7C°

)

10

10.0F°/5.6C°

Note:

The use of a larger proportional band is not to use the 

thermostat as a discharge air controller device. The use of a larger 
proportional band can be used to solve issues for flawed HVAC 
design with basic sizing and thermostat location errors that cannot 
be worked around.

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 memory.
