10.2.1 Compressor and electric emergency/booster heater
Note
The appliance can be operated in single-phase or three-
phase mode.

Effect of the electric emergency/booster heater
Mono energet-
ic operation
If the dual mode point is undershot, the electric emergency/
booster heater safeguards both the heating operation and the
provision of high DHW temperatures.
Emergency
mode
If the heat pump shuts down due to a fault, the heating output
is covered by the electric emergency/booster heater.
 Connect cables according to the following diagram.

 Route cables and leads through the strain relief fittings.
Check that the strain relief fittings are working as intended.
If no voltage is applied to the power supply utility enable signal,
the heat pump will not start.
 If no ripple control receiver is fitted, install a jumper be-
tween EVU1 and EVU2.
