The control unit detects the water shortage if
a there is zero potential at the WM input of the
control unit.
Note the following when connecting a vapor-
iser
• The neutral conductor (N) of the vaporiser
must be connected.
• If the entire output of the vaporisers to be
connected exceeds the maximum switch-
ing output (3 kW) of the vaporiser outlet,
an additional output controller must be
connected to terminals S1/N/V on the re-
lay box‘s circuit board, e.g. LSG18H.
Connect the vaporizer to the terminals ( D ) +
ground.
A heat-resistant cable must be used to connect
the vaporiser. It must have a cross-section of at
least 1.5 mm².
You can connect more than one vaporiser. If
correctly connected, each vaporiser can report
a water shortage separately.
See Checking for proper installation of the va-
poriser.
Vaporiser (only H-series)
WARNING
Fire hazard from overheating
If the connection for the water bath (WB) and
water shortage (WM) are swapped, the thermo-
stat is jumpered. The water shortage cannot be
detected. The vaporiser overheats.
• Do not swap the connections for the water
bath (WB) and water shortage (WM).
• Check for proper functioning after instal-
lation.
Checking for proper installation of the vapor-
iser
If installed properly, the vaporiser will switch on
and off according to the humidity setting.
• If the
Wb
and
Wm
connections on the
vaporiser are swapped, the vaporiser
will not switch off and continue to run
uninterrupted.
• If the line to Wm is disconnected, the
Water shortage error message has to
appear.

Vaporizer connection
Connect the sauna heater to the terminals ( C )
+ ground
The neutral conductor (N) of the sauna heater
must always be connected because, in humidi-
ty mode, one phase is rerouted from the sauna
heater to the vaporiser. This results in an asym-
metrical heating load and power flows through
the neutral conductor. (only H-series).
The switching output of the control unit for the
sauna heater has a max. of 9 kW resistive load.
It can be expanded as needed by an optional
output controller (LSG) so that it is possible to
connect sauna heaters with an output greater
than 9 kW.
To connect the optional LSG, see the installa-
tion instructions for the relevant LSG.
