Humidity operation
The prerequisite for humidity operation is
the connection of a suitable evaporator unit
up to max. 3 kW to 230 V AC. The control
"clocks" the evaporator, dependent on the
set nominal humidity value.
Note:
Whilst the evaporator is being
switched on, the heater only works with 2
phases, meaning that part of the power is
switched to the evaporator. On symmetri-
cally wired heaters (same heating output per
phase) 1/3 of the heating output of the sauna
heater is therefore switched off. This serves
on the one hand to protect the user from ex-
cessive temperatures, but also to limit the
switching capacity to 3.5 kW per phase
.
The humidity to be achieved is strongly de-
pendent on the geometry of the sauna cabin,
the sauna heater used and the evaporator
power
. Therefore, you will have to fi nd your
own personal climatic zone. Always select
the temperature fi rst (from 30 to 70°C) and
then the humidity.

The evaporator is always activated if a value
is displayed in the fi eld „Humidity“. Please
also observe that the evaporator does not
switch on until the temperature has dropped
to this value.
Heaters and evaporators which are optimal-
ly adapted to the sauna cabins can be used
to achieve the humidity values given in the
table with a 100% duty cycle.
These achievable values lie higher than the
values which are actually required. There-
fore, after heating up, please lower them.
Please observe that the cabin temperature
is highest directly under the cabin ceiling,
whereas the relative air humidity is low. The
relative air humidity increases as the tem-
perature sinks towards the cabin fl oor.

tive air humidity temperature values for the

The humidity intensity shown in the display
corresponds to the time proportional evapo-
rator setting. Therefore, the relative air hu-
midity is not preselected or shown on the
display, but rather the switch-on frequency
of the evaporator in percent. The graphic is
intended to clarify this.
