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.

Note
For every appliance fault, output X2.10 issues a 230 V
signal.
In the case of temporary faults, the output switches the
signal through for a specific time.
In the case of faults that result in a permanent appliance
shutdown, the output switches through permanently.
f
You can define the characteristics of the output via
parameter "COMMISSIONING / I/O CONFIGURATION /
OUTPUT X 2.10".
