The heat pump and the recuperative unit operate independently of each other, therefore the
ventilation ducts should also be separated. This means that when the recuperation is working and
the heat pump is stopped, then the air flows easily to the ventilation outlet and not to the heat
pump. This would reduce the efficiency of the recuperative air handling unit fan.
Note : In addition, the intake and ejection of air from the room in which the pump is installed is
permitted. However, this may lead to a reduction in energy efficiency.
3.5 Electrical connection
The heat pump is powered by 1~230V/50 Hz. As a standard it has a plug with a cable of 1.5 m length.
Important : It is recommended that the electric supply circuit of the heat pump was equipped in the
circuit breaker with characteristic "C" and residual current device with rated differential current
transmission of 0.03A.
Note: All work related with the installation of these elements should be performed by personnel with
the appropriate permissions and qualifications. As a standard there is a possibility of connecting
electric heater up to 1.5 kW. If electric heater with more power is needed, replace the existing power
supply cable.
The sensor cable can be extended up to 5m.
For its extension can be used e.g. cable type H03VVV-F 2x0.5mm^2 or with similar parameters.
If the heat pump controller does not work, first check the fuse on the heat pump supply circuit and
then the fuse placed on the control board inside the heat pump. For this purpose, the heat pump
housing must be partially removed.
