Hot water production
The electric element keeps the water heater hot via the sensor for hot water
(T3), which is on the heater’s outer shell.
Heat production
In the event of a heat demand, the shunt valve opens under the water heater
and releases heat to the radiator system. The temperature of the radiator
system is regulated via the fl ow line sensor (T1) and the heating settings in
the control unit.
Extra hot water and hot water peaks
The electric element ensures an increase of the temperature in the water
heater so that the desired demand is met.
