Danger!
Mains connection terminals L and N remain live
even when the boiler on/off control is switched
off.

nections 7-8-9 or BUS (+,-).

clamps in the rear of the control box and are
securely fixed. Ensure that the power supply is
connected such that the current carrying con-
ductors become taut before the earth conductor
should the supply cord slip from the cable clamp.
