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. Two floor temperature sensors are
provided - one with the DITRA-HEAT-E-RS thermostat and
one with the DITRA-HEAT-E-HK heating cables. Both floor
temperature sensors are installed within the tile assembly.
One sensor is connected to the thermostat, while the other
is stored in the thermostat electrical box. The second sensor
can be easily connected in case of damage to the first sensor.
