A Varity of errors can be recognised and displayed by the
control unit..
The red LED shines in case of an error. The illustration
shows the position of the displayed error.
The heat pump was switched off by
the High pressure switch. At more than 3 switches off this
way in 24 hours the heat pump is blocked and has to be
switched off and back on by the main switch.
The heat pump was switched off by
the Low pressure switch. At more than 3 switches off this
way in 24 hours the heat pump is blocked and has to be
switched off and back on by the main switch.
The heat pump was switched
off by the Thermo relay switch (Motor protection). At
more than 3 switches off this way in 24 hours the heat
pump is blocked and has to be switched off and back on
by the main switch.
The Groundwater
temperature is to low. After a temperature increase the
Heat pump switches back on automatically.
The Heat pump is operating for
more than 180 minutes without increasing the
temperature. As soon the temperature increases the
Heat Pump switches back on.
One of the necessary sensors
is not working. You can find out which by going to
“overview temperatures” (page 17)
The relation between operation
hours and switch impulses is bad.
The gap between flow and return temperature
of the heat pump is too big. Check mixers.
The heat pump
was switched off by the Max. temperature threshold and
will switch back on as soon the temperature reaches
49°C.
