Electrical hook-ups

The product is supplied already wired for the
supply network. It is powered via a cable
and plug/socket (Fig. 11 and Fig. 12).
Connect the appliance to the power supply
using an earthed Schuko plug with separate

Installation, use and maintenance manual
WARNING: the electric power
supply the
connected to must be protected
by a suitable circuit breaker.
The circuit breaker should be
chosen according to the type of
electrical devices used in the
whole system.
When hooking up to the power
supply and in relation to the
safety devices (circuit breaker
etc.), see IEC standard 60364-4-

Remote connections

The appliance can be connected to other
remote energy systems (photovoltaic and
solar thermal power).
The user interface has two digital inputs with
the following functions:
 Digital 1: solar
When a dry contact is closed between
terminals 30
brown/yellow wires) and the water
temperature as measured by NTC1 is
greater than SP8, the heat pump stops
and the water is heated via the solar
panel circuit. The heat pump starts
again when the contact is released and
the time set under C13 reached, or
immediately if the low boiler probe
temperature is below SP8
 Digital 2: solar
When a dry contact is closed between
terminals 31 and 32 (cable: green/white
wires) and the heat pump reaches the
temperature set under SP5 (pre-set to
62°C), the nominal
temperature is increased by 7°C. By way
