• In the case of RCH/KRCH units, the automatic
humidity function operates with priority. Switch-
ing through the DS RC or through a radio win-
dow contact is possible during humidity operat-
ing mode.
Radio window contact (EnOcean switch)
• Radio window contacts can be taught-in for
each fan.
• The radio window contact sends the
Window
open
or
Window closed
status to the assigned
fan.
• The assigned fan switches off automatically if
the window is opened.
• If you want the fan to continue to operate even
when the window is open, it can be switched on
with the assigned radio switch.
• The radio switch has priority over the radio win-
dow contact and/or the RLS RC.
• The fan switches off again after a timeout of ap-
prox. 30 minutes (if the window is still open) or
back to the operation mode set on the RLS RC
(if the window is closed).
• In the case of RCH/KRCH units, the automatic
humidity function operates with priority. Switch-
ing through the DS RC or window contact is
possible during humidity operation.
RLS RC room air control (EnOcean radio con-
trol)
For information about the RLS RC room air
control, see separate installation instructions.
• The RLS RC room air control is a radio control
for the manual operation of master and slave
devices.
• Two programs (P1/P2) with different power
level combinations are available for operation.
• The programme suitable for the application (P1
for small/P2 for large residential units,→ tables
in chapter
ing commissioning.
• The following appears in the RLS RC display:
System level 0/Off without bar
System level 1 with two bars
System level 2 with 4 bars
System level 3 with 6 bars
• The time and temperature are also shown on
the display.
• The holiday mode is equipped with interval op-
eration. The on-off change takes place every 30
minutes for all fans (humidity protection). Radio
commands from further radio network devices
are ignored until holiday mode is switched off.
• Service menu for system settings.

6.1 Ambient conditions
• Permissible maximum temperature of air me-
dium + 40 °C.
• Sufficient supply air intake must be ensured
during operation with air-ventilated fireplaces.
The maximum permitted pressure difference
per residential unit is 4 Pa.
• Resistance to interference according to EN
55014-2 depending on pulse shape and energy
component 1000 to 4000 V. If operating with
fluorescent tubes, extra interference suppres-
sion measures are needed (L or C components
or RC modules, protection diodes, varistors) be-
cause these values may be exceeded.
• Storage: Store unit exclusively in a dry location
(-20 to +50 °C).
