With the cable we have taken into account laying B2 from the table A.52.4
– IEC 60364-5-52. The cable in the
installation pipe is fixed to the wall. The dimensions of the electrical cables must always be checked or determined by
the designing engineer of electrical installations.
5)
Total maximal load (circulation pumps, electronic valves ...) which can be connected to or powered by the internal unit,
must not exceed 500 W. Bigger consumers (i.e. Pumps) should have their own supply.
6)
The circulation pump must be dimensioned in such a way that it ensures rated flow through the heat pump.
7)
This applies to pipe connections of suitable dimensions and total distance of up to 20 m. Pipe dimensions and types of
pumps must always be verified or determined by the designing engineer of electrical installations. Circulation pumps
must be dimensioned to ensure rated voltage (see table) through the heat pump.
8)
Connection to the internet is not necessary for the operation of the device but it is necessary for remote control through
the Home Cloud service. It is also advisable for faster troubleshooting of the device
’s operation.

The size of the fuse depends on the choice of the connection power of the electrical heater.

When connecting a 4 kW electric heaters in single-phase power supply system it is necessary to obtain a guarantee or
consult with the operator of the distribution network that the impedance of the network is less than the max. Thus, the
device will operate within acceptable limits of interference.
