ELECTRICAL ADDITION - MAXIMUM OUTPUT
The immersion heater output is divided into 7 steps,
according to the table.
The immersion heater is adjustable up to a maximum
of 9 kW. The delivery setting is 9 kW (does not apply to
1x230 V).
You reconnect to 7 kW by transferring the white cable
from terminal block X3:13 to terminal block X7:23 on
the immersion heater board (AA1). (The seal on the ter-
minal block must be broken.)
Setting maximum output in the electric additional heat
is done in menu 5.1.12.

The tables display the maximum phase current for the
relevant 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
indoor 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
29.
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 flow line, see chapter
Emergency mode thermostat on page 28.
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 6 kW.
