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.
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
