12.2.1 Compressor and electric emergency/booster heater
!
Appliance damage
The compressor must only rotate in one direction. If the
fault NO POWER appears in the WPM3i display when the
compressor starts, change the direction of rotation by
interchanging two phases.

Effect of the electric emergency/booster heater
Mono energet-
ic operation
If the heat pump cannot reach the dual mode point, the elec-
tric emergency/booster heater ensures both the heating oper-
ation and the provision of high DHW temperatures.
Emergency
mode
Should the heat pump suffer a fault that prevents its contin-
ued operation, the heating output will be covered by the elec-
tric emergency/booster heater.

Material losses
Do not connect a high efficiency circula-
tion pump directly to control output UP.
Use an external relay with a breaking capacity of at least
10A/250VAC or our relay set WPM-RBS.
If no voltage is applied to the power supply utility enable signal,
the heat pump will not start. The message “power-OFF” appears
on the controller. In this event, install a jumper across “EVU” and
phase “L”.
