ELECTRICAL ADDITION - MAXIMUM OUTPUT
The immersion heater output is divided into 9 steps, accord-
ing to the table.
The immersion heater can be set to a maximum of 12 kW.
The delivery setting is 8 kW.
Setting maximum output in the electric additional heat is

The table displays the maximum phase current for the relev-
ant electrical step for the indoor module.
If the current sensors are connected, the indoor module
monitors the phase currents.
NOTE
If the current sensors are not connected, the in-
door module performs a calculation of how high
the currents will be if the relevant power steps are
added. If the currents are higher than the set fuse
size, the power step is not allowed to cut in. See
chapter Load monitor on page 24.
EMERGENCY MODE
When the indoor module is set to emergency mode (SF1 is
set to
) only the most necessary functions are activated.
•
No hot water is produced.
•
The load monitor is not connected.
•
Fixed temperature in the supply line, see section Emer-
gency mode thermostat.
Power in emergency mode
The immersion heater’s output in emergency mode is set
with the DIP switch (SF1) on the immersion heater board
(AA1), according to the table below. The factory setting is 8
kW.

The image shows the dip-switch (AA1-SF1) in the factory
setting, that is 8 kW.
Emergency mode thermostat
The supply temperature in emergency mode is set using a
thermostat (FQ10-BT30). It can be set to 35 (preset, e.g.
underfloor heating) or 45 °C (e.g. radiators).
