using the two screws supplied.
5.Route wires coming from the wall through the hole of the
mounting base and make the required connections using the
“Four-wire installation” figure, and using the supplied solder-
less connectors. A pair of wires (black) must be connected
to the power source (120-208-240 VAC) and another pair
(yellow) must be connected to the heating cable (refer to the
drawings displayed on the back of the thermostat). For con-
nections with aluminum wires, you must use CO/ALR connec-
tors. Please note that thermostat wires do not have polarity,
meaning that any wire can be connected to the other. Then,
install the floor temperature sensor.
