Attention:
Always connect the neutral
(N) terminal at the sauna heater. In humid
mode one phase will be switched off, the
power load distribution will not be propor-
tional. As a result the N line will not be cur-
rentless.
!
ATTENTION
: pay particular attention to
the correct connection of the WB and WM ter-
minals. In case of swapped connection, the de-
tection of water shortage in the vaporizer will be
disabled and the protective thermo-fuse will be
bypassed. The vaporizer may overheat!
Risk of fire!
Connect the vaporizer as shown on the con-
nection diagram given below.
Make sure to use the appropriate heat-resistant
silicone cable with min. 1,5 mm² cross section
for vaporizer connection.
The control unit will detect water shortage if
there is zero potential at the Wm terminal of
the control unit.
Pay attention to the maximum switching pow-
er of the control unit vaporizer output. If the
total power of the vaporizer(s) exceeds the
switching power of the control unit, you will
need an external power switching relay box or
contactor box, e.g. LSG18H.
