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).
Electrical auxiliary heating system 2 kW/230, 4,5 kW/400 V~, 6 kW/400 V~ VAC with
built-in tank temperature controller and safety temperature limiter.
Screw electrical auxiliary heating system into the pipe coupling at the floor-standing
hot water tank (seal with hemp).
Set desired tank temperature at the tank temperature controller of the heating control
(60°C max).
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.

Fault-Cause-Remedy

Fault
Leakage at floor-standing
Aufheizzeit zu lang
Industrial water temperatu-
re too low
Cause
Flange leaking hot water
tank
Pipe connections leaking
Hot water temperature too
low (measure at the supply
of floor- standing hot water
tank, not at the boiler)
Heating water amount too
small (causes large sprea-
ding, i.e. return temperature
too low)
Heating coil does not bleed
Calcification of heating
surface
Thermostat switches off too
early Return temperature too low
(e.g. excessive spreading)
SE-2
Remedy
Re-tighten screws
crosswise with 20-25
Nm;Replace seal
Re-seal
Increase temperature
(adjust controller)
Larger pump
Observe back pressure
of parallel heater circuit
Bleed repeatedly with
switched-off pump
Decalcify heating sur-
face
Reset thermostat
Larger charging pump
