Leaving the standby mode
When the thermostat has been put in standby mode from the True Comfort app,
press twice on or to turn back ON the thermostat. The thermostat will
resume operation under its last program settings.
A thermostat that is placed on standby before a power failure will be on standby
by default when power is restored.

GFCI protection:
Class A (5mA)
The thermostat is equipped with a
ground fault protection that can
detect a current leakage of 5 mA.
When a current leakage is detected,
the ground fault protection is
triggered and quickly interrupts the
power supply to prevent any
serious injuries.
Resetting the ground fault protection
The RESET button warning light turns ON (red) when the ground fault protection
is triggered. If the RESET button warning light turns ON during normal operation
of the thermostat, simply press the RESET button to reset the ground fault
protection. The light will turn OFF. If for any reason this situation occurs again, cut
the power to the heating system from the main electrical panel and ask a
qualified electrician to verify the installation.
Testing the ground fault protection
This thermostat has an Auto Test which periodically verifies the correct operation
of the protection circuit. You can also do this manually:
1) Press the TEST button. If the RESET button's red warning light does not turn ON,
the test has failed. Cut the power to the heating system from the main electrical
panel and ask a qualified electrician to verify the installation.
2) Press the RESET button to restart the thermostat's base.
4) Maximum limit of the ambient temperature (F mode)
Thermostat limits floor heating so as not to exceed the set ambient
temperature limit
5) Maximum floor temperature limit
The thermostat limits floor heating to the set temperature to ensure it does
not exceed the selected limit: ideal for protecting engineered wood floors.
This parameter can only be used when a floor sensor is connected to
the thermostat.

Warnings
Before starting the installation of your new thermostat, make sure that the
breakers for your heating system are off at the main electrical panel!
The installation of this thermostat must be performed by a certified
electrician and comply with the national and local electrical codes
and regulations.
1
Connect the sensor.
(Only for control applications in
F mode or with floor limit.)
3
Connect the heating floor by using the load / line wire
connectors located on the back of the thermostat.
Connect the ground wire to the screw in the electrical box
intended for this purpose.
2
Use the screws to secure the
thermostat to the electrical box.
Replace the cover and lock.
4
Power up the thermostat.
After performing a test sequence, the
thermostat should display the floor
temperature. If not, refer to the
troubleshooting guide in
this manual.

3-year limited warranty
Stelpro warrants their thermostats against defects in material and workmanship for a
3-year period from the date of purchase, under normal use and service, when proof of
purchase of such is provided to the manufacturer. This warranty does not cover any
transportation costs that may be incurred by the consumer. Nor does it cover a
product that has been improperly installed, misused or accidentally damaged. The
obligation of Stelpro, under the terms of this warranty, will be to supply a new unit and
this releases the manufacturer from paying the installation costs or other secondary
charges linked to replacing the unit or the components.
6) Minimum floor temperature limit (A mode)
The thermostat limits the minimum temperature of the floor in order to keep
it at a comfortable temperature.
This parameter can only be used when a floor sensor is connected to
the thermostat.
7) Assigning the auxiliary output:
The thermostat provides an auxiliary output that has three functions which
are set from the user settings.
15 sec function:
Short cycle auxiliary output (15 seconds): used for a heater
controlled through an electronic relay (SSR).
15 min function:
Long cycle auxiliary output (15 minutes): used for a heater
controlled through an electromechanical relay or equipped with a fan.
In the 15 sec and 15 min functions, the thermostat controls the ambient
temperature with the floor. Once the floor temperature has reached its limit,
if the desired ambient temperature is not reached, the auxiliary output
activates the heating device to reach the set temperature. (The auxiliary
output acts as a second heating stage.)
EXP function:
Auxiliary output to connect several heating floors
(expansion unit sold separately)
OFF function (default):
Disables the auxiliary output.
