Connection of the booster heater cable depends on the application. Only when the domestic hot water tank is installed will
this wiring be needed. The unit only sends a turn on/off signal to the booster heater. An additional circuit breaker is needed
and a dedicated terminal is needed to supply power to the booster heater.
See also "8 Typical application examples" and "10.7 Field settings/DHW control" for more information.
Procedure
Connect the cable to the appropriate terminals as shown in the picture.
Fix the cable with cable ties to the cable tie mountings to ensure stress relief.
