This button is used to set the required

The different operating modes are:
Auto mode: VVM 240 automatically selects the oper-
ating mode by taking the outdoor temperature into
account. The circulation pump and the immersion
heater are permitted to run as needed.
Summer mode: Only production of hot water using
FIGHTER 2010. The circulation pump and immersion
heater are blocked. However, when Extra hot water is
activated the immersion heater is connected.
Spring/Autumn mode: Only production of heating
and hot water using FIGHTER 2010. The circulation
pump is operational. The immersion heater is dis-
abled. However, when Extra hot water is activated the
immersion heater is connected.

returns to the normal display mode once the enter but-
ton is pressed.
