4. Align and secure the mounting base to the connection box
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
solderless 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 connections with aluminum wires, you must
use CO/ALR connectors. Please note that thermostat wires
do not have polarity, meaning that any wire can be connected
to the other. Then, connect the wires of the floor temperature
sensor at the indicated location behind the thermostat.
