installation
The electrical connection must be done by a suitably
qualified heating engineer who is responsible for com-
plying with the existing standards and guidelines.
Danger!
Risk of death from electric shock through con-
tact with live connections!
Isolate the mains power supply before working
on the unit, and ensure that the power cannot
be accidentally restarted.
Using the mains switch on the VR 65 or on the
heating appliance is not sufficient to isolate all
terminals of the system.
Caution!
In order to avoid damage to the heating appli-
ance or the VR 65 Control Centre, any existing
230 V wiring box installation must be removed
completely.
