Load monitor

Currents sensors are connected on AA3-X4:1-4.

Function:

႑If any of the internal phases exceed the set value and

the phase sequence is not detected, the power step

disconnects from one of the internal phases. Because

the phase sequence is not detected this can mean

that the incorrect phase sequence is disconnected,

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

the external additional heat, if such exists 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.

႑If 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.

႑If disconnecting the phases does not work, the heat

pump will finally disengage.

႑Reconnection 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 in the installation. In the menu 5.1.12

the phase sequence must be detected afterwards. An

unsuccessful detection may be due to the current

sensors not being correctly connected or that other

electrical equipment started or stopped during detec-

tion.
