TEC2145-4 N2 Networked Thermostat Controller with Single Proportional Output and One-Speed Fan

Control Installation Instructions

13

St-By TM

1

Sets stand-by timer value; time 
delay between moment where 
occupancy sensor detected the last 
movement in the area and the time 
which the thermostat stand-by mode 
and setpoints become active.
Default: 

0.5 hours

Range: 

0.5

 to 

24.0

 

hours

, in 0.5 hour increments

Unocc TM

1

Sets Unoccupied Timer Value; time 
delay between the moment where 
the thermostat controller toggles to 
stand-by mode and the time which 
the thermostat controller 
unoccupied mode and setpoints 
become active.
Default: 

0.0

 hours

0.0 hours 

or Factory Value: Setting this parameter to its default 0 

value disables the occupied timer and prevents the thermostat 
controller from drifting from stand-by mode to unoccupied mode 
when occupancy sensor functions are used.
Range: 

0.0 

to 

24.0

 

hours

 in 0.5 hour increments.

St-By HT

1

Sets Stand-by heating setpoint; 
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

1

Sets Stand-by cooling setpoint limit; 
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

100.0°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

100.0°F/37.5°C

Pband

Proportional Band used by the PI 
temperature control loop of the 
thermostat controller.
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°

)

Value

F Scale Pband/C Scale Pband

3

3.0F°/1.7C°

4

4.0F°/2.2C°

5

5.0F°/2.8C°

6

8

8.0F°/4.4C°

9

10

10.0F°/5.6C°

Note:

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

thermostat controller 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 controller location 
errors that cannot be worked around.
