3.7. 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 project
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.
-
Connection of other devices (
IR14 RTC controller, auxiliary heat source, circulation pumps,
valve actuators, etc.
): connect according to the relevant instructions or project documentation.
A suitable heat pump circuit breaker for most installations under normal conditions is B16A 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) 3x2x0.75 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 3x2.5 mm

, unless otherwise stated in the design.
3.8. Addressing HP in a 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:
