When the current supply temperature deviates from the set
value compared to that calculated, the heat pump is forced to
stop irrespective of the degreeminute value.

temperature plus the set value, the degree minute value is set to
0. The compressor in the heat pump stops when there is only a
heating demand.
max diff addition
If "addition” is selected and activated in menu 4.2 and the
present supply temp exceeds the calculated temperature plus
the set value, the additional heat is forced to stop.
Menu 5.1.4 - alarm actions
Select how to control the heat pump in the event of an alarm.
You can choose to stop producing hot water and/or reduce the
room temperature.
CAUTION
If no alarm action is selected, it can result in
higher energy consumption in the event of an
alarm.

Select this option if shunt controlled additional heat is
connected.
Set when the addition is to start, the minimum run time and the
minimum temperature for external addition with shunt here.
External addition with shunt is for example a wood/oil/gas/
pellet boiler.

Selecting "prioritised additional heat" uses the heat from the
external additional heat instead of the heat pump.
The shunt valve is regulated as long as heat is available,
otherwise the shunt valve is closed.
