NIBE™ VVM 500Chapter 3 | System description8

Load monitor
The current sensors are connected to AA3-X4:1-4.
Function:
■If any of the internal phases exceed the set value and
the phase sequence is not detected, electrical power
is disconnected from one of the internal phases. Be-
cause the phase sequence is not detected this can
mean that the incorrect phase sequence is disconnec-
ted, so that the output is still too high. The heat pump
continues by disconnecting another phase, until the
current does not exceed the set value. If the current
still exceeds the set value when all internal phases
are disconnected, the same process is performed for
external additional heat, if applicable and is set to
step-controlled additional heat.
NOTE
Do not disconnect the external additional
heat if it is set to give additional heat in one
step.
.
■If the phase sequence is detected the electrical out-
put is disconnected in the phase that exceeds the set
value. This will also handle any external additional
heat.
■If disconnecting the phases does not work, the heat
pump will finally disengage.
■Reconnection occurs when the current has fallen to
a value low enough to permit reconnection.
NOTE
VVM 500 must be filled with water before the
phase sequence is detected.
For the heat pump to disconnect the electrical output
in the correct phase, the phase sequence must have
been detected during the installation. In the menu
5.1.12 the phase sequence must be detected after-
wards. An unsuccessful detection may be due to the
current sensors not being correctly connected or that
other electrical equipment started or stopped during
detection.
