NOTE : The power module must be

procedure should be performed by a qualified
electrician where required by law & persons aware
of the hazards involved. Please contact your
distributor for further instructions
Use the following information to troubleshoot your comfort
controller.
Room T "*" - Indicates the floor sensor is not working or is
unplugged. No need to worry, your ThermaRay controller
defaults to the Face Sensor. Your floor warming system
will continue to function normally. You may want to do one
of the following:
A. Remove the controller from the wall by removing
the two white screws. Check to see if the floor
sensor is properly connected in the floor sensor
receptacle.
B. Leave everything as is.
C. Replace the floor sensor. You can embed a
sensor in a grout line, taking care not to damage
the cable. You may have to adjust your set point
as the sensor will be in a different location with
relation to the floor cable
Garbled Screen - Press and . If this does
not work, remove the controller from the wall by removing
the two white screws. Unplug the Power Module plug and
wait one minute. Plug the controller back in and remount
to the wall. Garbled screens are due to voltage
fluctuations caused by surges or brown outs. If this
happens often permanent damage may be done to the
controller. To prevent this, you may want to have a surge
suppressor installed for the breaker that powers your
heating system.
No Answer- This is a remote function error. Check that
the thermostat is firmly plugged in.
Room T - 50 (°F or °C) - The face sensor is broken and a
new controller must be installed. If the floor sensor is fine,
you will not receive this message and your system will
operate normally.
Heat Continuously On - Check to see if the arrow is on
the screen. If it is not, check to see if the power module is
putting out power to the heating circuit. If it is, a new
power module is needed.
