Minimum run time is the number of seconds the thermostat will call for heating
or cooling to ensure a comfortable cycling rate. Setting the System to Off or the
opposite system call will override the timer and immediately terminate the heating
or cooling call.
The minimum run time (MRT) upper limit is tied to the Stage Delay Timer (SDT)
setting (600s or 10min by default). The upper limit for MRT may be set as high as
90 minutes, if the SDT is set accordingly.
