Addition
Immersion heater (EB1)
The immersion heater can be set up to a maximum of
9 kW.
Delivery setting is 9 kW.
The immersion heater output is divided into 7 steps.
These 7 steps can then be restricted by BT63 as be-
low.
Temp BT63 (°C) No. of permitted steps
>80 0
>77 1
>74 2
>72 3
>72 No restriction
Max. output
As there are regulations that determine the maximum
permitted electrical output for heating a building, the
immersion heater’s maximum output is locked to
comply with these regulations.
One week after setting maximum output, the system
locks permanently at this value and the display unit
must be replaced if one later needs to increase the
maximum output.
Heating mode
During heating operation the immersion heater is
controlled by the degree minute calculation.

Hot water operation
All additional heat must have been stepped out be-
fore changing to hot water, see calculating hot water
demand.
When shifting back to heating, the additional heat
step must be stepped in as indicated by DM.

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, electri-
cal power is disconnected from one of the inter-
nal 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 discon-
necting another phase, until the current does not
exceed the set value. If the current still exceeds
the set value when all internal phases are discon-
nected, the same process is performed for ex-
ternal additional heat, if applicable and is set to

Do not disconnect the external additional heat if it is
set to give additional heat in one step.
step-controlled additional heat.
• If the phase sequence is detected the electrical
output 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.
