pConnect the thermostat to the power supply and to the load (see page 7).
qConnect the floor sensor (see page 8).
rIf you wish to connect a remote control device, see page 8.
sInstall the wallplate to the electrical box using the provided screws.
tSet the configuration switches on the back of the faceplate (see page 9).

nInsert the floor sensor cable through one of the two
openings on the wallplate and connect the sensor
wires to terminals 1 and 2 (no polarity).
• The sensor cable must pass outside the electrical
box and follow the wall down to the floor.
• Position the sensor cable such that it does not
come in contact with the floor heating wires. The
sensor must be centered between two floor heating
wires for best temperature control.
• Do NOT staple the sensor head (the plastic end) to
the floor. Doing so might damage the sensor. Any
damages might not be noticeable during testing but
can become apparent several days later.
oIf 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 wallplate and connect
them to terminals 2 and 3 (no polarity). Connecting a
remote device enables you to place the thermostat on
vacation mode from a remote location. See page 17.
