ELECTRIC CONNECTIONS
The devices are equipped with the following electric
connections. Main circuit connection 230 V 50 Hz, room
thermostat connection and – with the exception of the
PV types – heating pump connection. These connections
– which are of serial hook execution and are provided
with the appropriate labels – are located within the
appliance box.
Access can be achieved in the following way:
o
Lift off the top of the boiler, which is fixed by
snaps.
o
Screw out the screws of the top of the appliance
box; now you have access to the connecting
hooks.
There is 230 V 50 Hz voltage present on the
connectors of the device, therefore, in order to avoid
accidents, before you remove the top of the
appliance box, turn off the external separator switch!
The connection of the room thermostat can be
double-wired or, if it is necessary for the operation of
the thermostat, triple-wired.
