4 Electrical connection
The appliance must be connected to a
230 V~ supply via the mains plug.
(For the VER 100/3 - VER 200/3).
A PE conductor is not present, since
the appliance is of the totally insulated
type.
The regulations of the local electricity
board must be observed.
The appliance must be installed so
that it can be disconnected from the
supply before any intervention (e. g.
pulling out the mains plug for VER
75/3 - VER 200/3).
The connecting lead is specific to con-
vectors.
Changing the connecting lead must
only be carried out by an approved
contractor.
Only use original Vaillant special-
purpose cables.
5 Starting up

The built-in room thermostat keeps the
required room temperature constant.
If a room which is not being used is to
be protected against frost, set the ther-
mostat knob (2) to position (
❄
).

The heater is switched off when the O

mostat (fig. 5.1).
