Heat Pump Control Unit Power Supply 230 V; Outdoor Unit Power Supply 230 V~/400 V - Viessmann Vitocal 200-S Installation And Service Instructions For Contractors

Installation sequence
Power supply
(cont.)
The assignment of the power-OFF (for compressor
■
and/or instantaneous heating water heater) is made
via the type of connection and by setting parameters
in the heat pump control unit.
In Germany, the power supply can be cut for a maxi-
mum of 3 x 2 hours per day (24 h).
The heat pump control unit/PCB must be supplied
■
without power-OFF. Tariffs subject to possible shut-
down must not be used here.
■ When using power generated on site (use of power
generated by the PV system to meet own require-
ments):
During the power-OFF period, it is not possible to
operate the compressor utilising power generated on
site.

Protect the power cable to the heat pump control unit
■
with an MCB/fuse of max. 16 A.
■ For accessories and external components that will
not be connected to the heat pump control unit, pro-
vide the power supply via the same MCB/fuse, or at
least on the same phase, as the heat pump control
unit.
Connection to the same MCB/fuse provides addi-
tional safety when the power is switched off.
Observe the power consumption of the connected
consumers.
■ The PE wire of the power cable must be approx.
10 mm longer than the N and L wires.
Note
This supply must never be blocked.
