Control for charging pump / electrical
auxiliary heating system E2 / E4,5 / E6
Insert electronic tank temperature sensor of the heating control into the immersion
sleeve for tank sensors of the floor-standing hot water tank and attach it with sensor
holder. For tanks with sensor channel insert sensor vertically downwards until stop
position is reached.Set desired tank temperature at the tank temperature controller of
the heating control (max. 60°C).
Weather-dependent heating
control with integrated tank
temperature controller and tank
temperature sensor
The connection must be performed by a licensed electrician.
The rules and regulations of the VDE and the local utilities must be observed.
Disconnect power before opening devices.
Unscrew cap from electrical auxiliary heating system and connect system to 230VAC
power supply according to circuit diagram. Connecting wire must be provided on site.
