Q If an insulation test is to be carried out in the building,
disconnect the heat pump.
Phase sequence monitor
The phase sequence monitor starts as soon as the power
supply is connected to the heat pump. Check the phase
sequence as shown below.

flash in event of incorrect phase sequence.
Q If there is a fault in the phase sequence, the heat pump
triggers a brine alarm in both modules.
Q Connect the heat pump to the terminal block X9, 400
V 3-phase, neutral + earth via a distribution board with
fuses. Where there is more than one heat pump, each
unit must have a separate supply.
