New Construction Rough-In
• F asten electrical connection box (as required per local electrical code) at desired position on side of stud.
• D rill one 1-inch hole in base plate for single-cable installation and two 1-inch holes for two-cable installation.
• Thread pull-cord through hole(s) in base plate and in corresponding holes in electrical box. Secure the pull cords in the electrical box.
Tie floor ends of pull-cord together with Warning Tags and fasten to floor.
• Install the guard plate over the hole for the cold leads and sensor wire before drywalling.
• Install guard plate as shown in Figure 1.
Thermostat Installation
• 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.
• Ensure the supply branch circuit has been disconnected / de-energized.
• Prepare the thermostat for installation:
1. Remove the thermostat, wire connectors and screws from packaging.
2. Pop out the Screw Cover by gently pushing from behind, with a screwdriver, see Figure 3.
3. Trim excess length of supply branch circuit, cold lead and temperature sensor cables, as necessary, leaving about 6" projecting from the Electrical
Connection Box (ECB), see Figure 4.
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
corresponding BLK and WHT terminals.
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, then finish tightening the two screws.
8. Snap the screw covers over the screw heads.
