4.6. Electrical wiring
Electrical connection and any interventions in it may only be carried out by a qualified person
with the appropriate authorization!
Check that the power supply to the utility room is sufficient and in accordance with the design
documentation, resp. according to valid standards and regulations. The cross-section of the
supply cable for the entire heating technology depends on the application and the output of
the auxiliary heat source.
Connect other devices (IR14 RTC controller, auxiliary heat source, circulation pumps, valve
actuators, etc.) according to the relevant instructions or design documentation.
A suitable heat pump circuit breaker for most installations is B20A 1f. If a residual current
device is installed in the heat pump circuit, it should be a G-type RCD (delayed).
Communication:
15 m communication cable LiYCY
(TP) 3×2×0.75 mm
2
is part of the controller supply.
Power supply:
the power cable is not included in the
delivery, we recommend using a power cable with
a cross-section of 3×2.5 mm

, unless otherwise stated in
the design.
4.7. Addressing HPs in cascade
The addressing of the individual heat pumps installed in the cascade is performed via DIP
switches 6, 7 and 8 on the JNP401 switch, which is located on the printed circuit board. The
default address is 2.
The setting options are as follows:
Address
Address
cable grommets
