Installation / Commissioning
The electrical connection must be performed accord-
ing to the electrical connection plan delivered with
the boiler. The electrical installation diagram does
not include any protective measures. These must
be additionally provided on the installation of the ap-
pliance, respectively the connection, in accordance
with VDE 0100 and the regulations of the responsible
power supply company.
The boiler is only to be installed in rooms correspond-
ing to the protection class of the appliance (IP20). To
prevent induction voltages, low voltage and power
current cables (230 V~) must be routed separately at
a distance of at least 10 cm. Where low voltage and
power current cables have to be installed in cable
ducts, these are to be kept apart by a separator.
Electrical connection (grid) 230 V, 50 Hz
3.6.2
The boiler is wired ready for connection. It is fitted with
a connector cable of approx. 1.5 m length with main
connector plug. A socket is to be installed directly
adjacent to the boiler (maximum 1 m from the edge
of the casing).
The fusing is to be selected so that the limits detailed
in the Technical Data are never exceeded.
Non compliance with this regulation can have seri-
ous consequences for the controller in the event of
a short circuit.
When working on the gas boiler the appliance is to
be disconnected from the electrical supply!
The applicable accident prevention regulations and
the generally recognised rules of the art are to be
complied with for the electrical installation and com-
missioning.
Automatic firing units are safety devices and
are not to be opened.

T/N
In principle the TopTronic
®
T/N permits weather-
supported flexible heating operation of two regu-
lated mixer circuits, a direct circuit plus the hot water
provision with an indirectly heated water heater (e.g.
Hoval CombiVal). A possible hydraulic system is
detailed under chapter 3.4.6. Control possibilities
are expandable with key-modules.
