Setting the cooling technology
You must set the installed cooling technology.
When using ground/brine as the heat source, active cooling
is limited to a brine output temperature of 40 °C in order to
protect the source/probe borehole. If this temperature is ex-
ceeded (> 40 °C), active cooling mode is switched off. This
limit can only be changed by Vaillant Customer service.

Enabling the electric back-up heater
On the system control, you can select whether the electric
back-up heater is to be used for heating mode, domestic
hot water mode or both modes. Set the maximum output for
the electric back-up heater at the heat pump's control panel
here.
