AUTO The heat pump and the immersion heater are automatically controlled by the control sys-
tem.

operate. In this operating mode, peak-heating charging (anti-legionella function) of the hot
water will not run because the immersion heater is not used.
ADD. HEATER The control system only permits the immersion heater to be in operation.
HOT WATER In this mode the heat pump only produces hot water; no heat is directed to the heating
system.
