WARNING According to VDE 0730 the power supply for the controller must have a separate
main switch for life and neutral. Please observe local guidelines for grounding and
neutralizing!
As soon as there is power supply at the terminals 21, 22, 2, 6, 12 and 18 also the
terminal rows X3 and X4 will carry 230 V connections!
If a manual switch function is desired for pumps, even though the DHW charging
pump does not have on/off switches, external switches must be installed. All
accessories (sensors, selectors, etc.) must be connected according to the attached
wiring diagram.
