Installation Instructions
Programmable Thermostat

Applications
Position the sensor cable such that it does not come in contact
with the floor heating wires. The sensor probe must be centered
between two floor heating wires for best temperature control.
1.
This power base has been designed for floor heating applications. It
has ground fault protection (GFCI1 or EGFPD2) and an input for
connecting a floor sensor.
If your thermostat has the Vacation Mode, the mode can be activated
using a remote control device equipped with a normally open (NO)
dry contact. For more information on this mode, see the thermostat’s
user guide.

s
Install the thermostat onto an electrical box.
Do NOT install the thermostat in an area where it can be
exposed to water or rain.

Installation Procedure
4.
t
Verify the settings of the configuration switches (if any) on the
back of the control module (see user guide).
u
v
Install the control module on the base (see user guide).
w
Test the ground fault protection.
All electrical connections must be made by a licensed electrician. Failure to do so voids all warranties and claims.
n
o
Turn off power to the heating system at the main power panel in
order to avoid any risk of electrical shock.
Connect the power base wires to the power supply and to the
load using solderless connectors for copper wires.
If you wish to connect a remote control device, insert the wires
(use 18- to 22-gauge flexible wires) through one of the two openings on the base and connect them to terminals 2 and 3 (no
polarity).
Push the excess length of the high-voltage wires back inside the
electrical box.
Secure the power base to the electrical box using the provided
screws.
Apply power to the heating system. Verify the installation by
making sure that the heating system can be turned on and
turned off by increasing and decreasing the setpoint.

the base and connect the sensor wires to terminals 1 and 2 (no
polarity).

Ground Fault Protection
5.
5.1 Description
The power base protects against risks
of electrocution caused by leakage
current. If the leakage current exceeds
5 mA or 15 mA (depending on the
model), the ground fault protection will
automatically trigger, cutting power to
the floor heating system. To indicate
the fault, the TEST button on the top of
the base will illuminate (red).
TEST button/light
5.2 Ground Fault Protection Reset
When the ground fault protection has triggered, reset it by switching
the thermostat to Standby and back to On. The TEST button light will
go off.
5.3 Ground Fault Protection Test
To ensure the ground fault protection is always in working order, test
it once the thermostat is installed and on a monthly basis thereafter.
n
Increase the setpoint temperature above the measured floor
temperature in order to activate the floor heating system.
o
Press the TEST button.
• The test is successful if the TEST light is On (red). Reset the
thermostat and place it back to the desired temperature.
• The test has failed if the TEST light remains off. Cut power to
the heating system at the main electrical panel and replace
the thermostat.
