Thermostat Operation 

 

Minimum Run Time (MRT) 

The thermostat has a Minimum Run Time (MRT) delay after the start of any heating or 

cooling call.  This minimum run time assures even heating and cooling cycles.  The MRT 

will keep the system on, even if it reaches the setpoint room temperature, or you change 

the setpoint to a temperature that would satisfy the call, until the MRT expires.   Changing 

the Mode to OFF will cancel the MRT and the system will turn off immediately. The MRT 

can be adjusted in the Advanced Settings menu of the thermostat. 

 

Note:  The MRT status is shown in the thermostat Status display

.   

 

 

Minimum Off Time (MOT)   

The thermostat has a Minimum Off Time (MOT) delay after any heating or cooling cycle 

ends.  This delay prevents rapid heating/cooling cycles and also provides “short cycle 

protection” for the system compressor.  This delay may be noticeable when you change a 

setpoint and it does not respond immediately due to the MOT delay timer preventing the 

system from restarting.  The MOT delay time can be adjusted in the Advanced Settings 

menu of the thermostat but there is a minimum of 5 minutes delay to assure compressor 

protection. 

 

Note:  The MOT status is shown in the thermostat Status display.
