 Only connect energy efficient circulation pumps to
the pump connections if they have been approved
by us.
If energy efficient circulation pumps are used that have
not been approved by us, use a relay with a breaking ca-
pacity of at least 10A/250VAC or our WPM-RBS relay set.
 Route cables and leads through the strain reliefs.
 Check the function of the strain relief fittings.
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”.
