Minimum-Off Timer Compressor 
Protection

The thermostat has an adjustable Minimum-Off Timer that 
can be set from zero to five minutes (Factory Setting—five 
minutes). The Minimum-Off Timer can be bypassed 
through the Installer System Test or it can be bypassed 
permanently by setting the Minimum-Off Timer to 0 
minutes in the Installer Setup. The Minimum-Off Timer is 
activated after the compressor turns off:
— If the thermostat is system powered (common wire), 

the Minimum-Off Timer is also activated upon initial 
startup and after power interruptions.

— If there is a call for cooling or heating during the 

Minimum-Off Time, the thermostat displays “Wait.”

— When the Minimum Off Timer expires, “Cool On” or 

“Heat On” (heat pumps only)” appears solidly in the 
display and the compressor and fan turn on.

Outdoor or Indoor Temperature 
Sensor

Allow outdoor or indoor temperature sensor to absorb the 
air for a minimum of five minutes before taking a reading. 
See the Sensor instructions for more information.

Heat Pump Temperature Lockouts

Dual Fuel Heat Pump and Outdoor 
Sensor

In this operation, there is no external fossil fuel kit (dual 
fuel kit) installed; the thermostat controls this function:

1.

Choose correct heat pump application in Installer 
Setup Number 0170.

2.

Choose 

Outdoor Temperature Sensor for Heat 

Pump Temperature Lockouts

 

Option

 in Installer 

Setup Number 0340.

3.

Choose appropriate 

Balance Point Temperature

 

in Installer Setup Number 0350.

OPERATION IN HEAT MODE ABOVE BALANCE 
POINT (OUTDOOR TEMPERATURE)

When the outdoor temperature is above the selected 
Balance Point Temperature (ISU 0350), only the 
compressor operates and the fan (G terminal) energizes 
when the thermostat calls for heat.

OPERATION IN HEAT MODE BELOW BALANCE 
POINT (OUTDOOR TEMPERATURE)

When the outdoor temperature is below the selected 
Balance Point Temperature (ISU 0350), only the Fossil 
Fuel (auxiliary heat) operates and the fan (G terminal) 
does not energize when the thermostat calls for heat.

Heat Pump with Auxiliary (Backup) Heat 
and Outdoor Temperature Sensor

1.

Choose correct heat pump application in Installer 
Setup Number 0170.

2.

Choose 

Outdoor Temperature Sensor for 

Control Option 

in Installer Setup Number 0340.

3.

Choose 

Compressor Lockout Temperature

 in 

Installer Setup Number 0350.

4.

Choose 

Auxiliary Lockout Temperature 

in 

Installer Setup Number 0360.

NOTE: There is a 5°F deadband between Compressor 

and Auxiliary Heat lockout temperatures.

Operation in Heat Mode

When the outdoor temperature is:
— Below the Compressor Lockout Temperature, only the 

Auxiliary Heat operates.

— Above the Auxiliary Lockout Temperature, only the 

Compressor operates. See Fig. 31.

— Between the two temperatures, both the Compressor 

and Auxiliary Heat operate.
