Thermostat Operation

Minimum Run Time (MRT)
The thermostat has a Minimum Run Time 
after the start of any heating or cooling call. 
This minimum run time assures even heating 
and cooling cycles. The MRT delay will keep 
the system on even if reaches setpoint 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 Installer 
Settings menu of the thermostat.

Note: The MRT status is shown in the 
thermostat System Status on-screen labels.

Minimum Off Time (MOT)
The thermostat has a Minimum Off Time after 
any heating or cooling call is finished. This 
delay prevents rapid heating/cooling cycles 
and also provides “short cycle protection” for 
compressor calls. This delay may be 
noticeable when you change a setpoint and it 
does not respond immediately due to another 
call that has recently completed and the MOT 
delay timer is preventing the system from 
restarting. The MOT delay time can be 
adjusted in the Installer Settings menu of the 
thermostat. There is a minimum of 5 minutes 
delay to assure compressor protection.

Note: The MOT status is shown in the 
thermostat System Status on-screen labels.
