When a separate supply to the compressor, immersion
heater and the control system is required, to give them
separate tariff control, the following should be done:
■ Remove the 3 cables between terminal block -X9
and the EMC filter (60). Connect the supply directly
to the EMC filter.
■ Remove the 2 orange straps on terminal block -X9
and connect the control voltage to the outermost
terminals marked L and N on the wiring diagram.
