Parts
One (1) power base
Two (2) screws
Four (4) solderless connectors for copper wires
NOTE:
Special CO/ALR solderless connectors must be used for connecting
aluminum conductors.
One (1) floor sensor and one (1) flat tip screwdriver (F and AF floor
heating models only).
Guidelines
Turn off power to the heating system at the main electrical panel to
avoid electrical shock. The installation should be carried out by an elec-
trician.
High voltage thermostats must be installed onto an electrical box.
For a new installation, choose a location about 5 ft. above the floor and
on an inside wall.
The thermostat must be installed on an inside wall facing the heating
system (except for floor heating systems).
Avoid locations where there are air drafts (top of staircase, air outlet),
dead air spots (behind a door), direct sunlight or concealed chimneys or
stove pipes (except for floor heating systems).
Procedure
Connect the power base wires to the power supply and load using sold-
erless connectors for copper wires (figure 1).
If your thermostat is type F or AF (not A), insert the floor sensor wires
through one of the two holes below the terminals (figure 2) and connect
the wires to terminals 3 and 4 (no polarity).
The wires must run alongside the terminals and not go over them. The
wire must not cross any heating wires nor be placed directly on a heating
wire or adjacent to it. For best performance, the sensor probe should be
centered between the wires in the mat.
If you wish to use a remote controller such as the CT240 or CT241,
insert the cable (use 18 to 22 gauge flexible wires) into one of the two
holes available below the terminal board and connect to terminals 1 and
2 of the base (figure 2).
Push the excess length of the high-voltage wires back into the electrical
box.
Secure the power base to the electrical box using the provided screws.
If necessary, set the configuration switches on the control module (refer
to the control module user guide).
Install the control module onto the base.
Apply power to heating system.
