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

Page 17
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.
Trouble Shooting
The thermostat LCD reads “COOL ON”, but hot air is supplied
Or
The thermostat LCD reads “HEAT ON”, but cool air is supplied
Go to the thermostat info menu (pg 7) and double check that the
thermostat is configured correctly for the HVAC unit. Double check if it is
set for Gas/ Electric or Heat pump and if the changeover is set correctly.
If changing the settings does not fix the problem double check the wiring
to confirm it is wired correctly for gas/ electric or heat pump. Refer to the
wiring diagrams on pages 3 & 4.
The thermostat is displaying “No Link”
Here are a few steps to walk through to reestablish connectivity
1. Double check that there is a Wifi signal where the thermostat is
being installed. You can do this by confirming the wifi signal is
accessible from a smart phone or laptop.
2. Double check that the wifi credentials were entered correctly.
3. Press the restore default button
Working on the HVAC unit
When doing repair work on the HVAC unit, you can set the thermostat
into maintenance mode through the online software. This will override
the temperature settings for 2 hours so you can test the unit as needed.
