6)
The circulation pump must be dimensioned in such a way that it ensures rated voltage through the heat
pump.
7)
Applies to pipe connections of adequate dimensions and joint 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 in such a way so as to ensure rated voltage (see
table) through the device.
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.

After connecting the device it is necessary to acquire the guarantee or consult the operator of the
distribution network that the impedance of the network is lower than
Z
max
. This way the device will operate
within acceptable limits of disruptions. Otherwise it is necessary to connect the device to the network
using a soft start device.
