Installation shutdown
If the central heating system is not used for a long period, we
recommend switching the appliance off.
To stop the inside module, use the J/K ON/OFF switch and cut the
power supply on the house's junction box.
To shut down the outside module, switch off the power supply on the
junction box inside the house.
CAUTION
Antifreeze protection is no longer guaranteed
automatically if the mains supply is switched off.
