Power (Live and Neutral)
Heater (Live and Neutral or Switch Live only)
Floor sensor
Fil pilote (if necessary)
External/ 2nd floor Sensor (if necessary)
5.
Pull wires through wall box and complete
terminal wiring.
IMPORTANT: Ensure that multi stranded wires are fully
inserted into the terminals and secured tightly. Any
loose strands should be trimmed as they could cause a
short-circuit.
