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 a 5 minute delay to assure compressor 
protection. 
 

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