Use this function to program your heating schedule for each day
of the week. The controller accepts up to five set points per day
with the first starting at 12:00AM and the last ending at 11:59PM.
For Earth Storage - if your utility does not have the capability of
remotely turning off the power to your ETS system, we suggest
that you set your programs to turn off 10 minutes before peak
rates come into effect. This should avoid peak rate charges due
to clock misalignment.

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 or ETS
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.
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.
