New Construction Rough-In
• Fasten electrical connection box (ECB) as required
per local electrical code on side of stud.
• Drill one 1-inch hole in base plate for single-cable
installation and two 1-inch holes for two-cable
installation.
• Thread pull-cord (not provided) through hole(s)
in base plate and in corresponding holes in ECB.
Secure the pull cords in the ECB.
Tie floor ends of pull-cord and fasten to floor.
• Install the guard plate (not provided) over the
hole for the cold leads and sensor wire before
drywalling.
• Install guard plate as shown in Figure 1.
Thermostat Installation
• Ensure the supply branch circuit has been
disconnected / de-energized.
• Pull sensor wire into ECB and secure to the floor.
See Figure 2. The sensor must not cross or overlap
any other cable on the floor AND must be
embedded in the cementituous based mortar in
the same manner as the heating cables.
• The floor temperature sensor wire can be
extended to a maximum of 50 feet with UL or CSA
recognized wire 22 AWG rated for 300 V.
• Prepare the thermostat for installation:
1. Remove the thermostat and screws from
packaging.
2. Loosen the screw on the bottom of the Front Panel
and lift the Front Panel as shown in Figure 3.
3. Trim excess length of supply branch circuit,
cold lead and temperature sensor cables, as
necessary, leaving about 6” projecting from
the ECB, see Figure 4. Most heating cables are
provided with identification labels attached to the
end of the cold leads – ensure that these labels
remain on the cold lead inside the ECB.

4. Prepare each heating cable/cold lead for
connection/splicing and connection per Figure 5
or Figure 6, as applicable.
5. Prepare the sensor wire per Figure 5 or Figure 6, as
applicable. Use screwdriver for connection to the
sensor wire connections (black and white wires) to

6. Neatly fold all wiring into ECB and fasten
thermostat with #6-32 screws provided. Do not
apply excessive force to the thermostat. Apply
firm but continuous force until the screws can be
fully seated.
7. Align the thermostat power base, then finish
tightening the two screws.
8. Hook the Front Panel unit to the top of the Power
Base unit, swing down and press the Front Panel
into the Power Base unit slightly, tighten the screw
at the bottom of the unit.
