Setting maximum number of steps in the electric addi-
tional heat is done in menu 7.1.5.1.
Power steps of the immersion heater
If the current sensors are connected, SMO S40 monitors
the phase currents. If the current is too high, SMO S40
withdraws the last step that was applied.
EMERGENCY MODE
When SMO S40 is put into emergency mode, the sys-
tem works as follows:
• SMO S40 prioritises heating production.
• Hot water is produced if possible.
• The load monitor is not connected.
• Fixed supply temperature if the system has no value
from the outdoor sensor (BT1).
You can activate the emergency mode both when
SMO S40 is running and when it is switched off.
When the emergency mode is active, the status lamp
turns yellow.
To activate when SMO S40 is running: press and hold
the on/off button (SF1) for 2 seconds and select "emer-
gency mode" from the shutdown menu.
To activate when SMO S40 is switched off: press and
hold the on/off button (SF1) for 5 seconds. (Deactivate
the emergency mode by pressing once.)
