• With a demand signal (only with start delay switched off for
the supply of water preheated by solar energy). Briefly turning
a hot water tap on and then off signals demand so that the
water is then heated up to the set temperature.

solar energy has been set (service function b.F), the
appliance does not switch on until the start delay
has elapsed.
The demand signal enables gas and water savings.
