In cross-ventilation operating mode, venti-
lation units of the Fan1 group (exhaust air)
are operated with a higher volumetric flow.
Volumetric flow compensation is automatic in
demand-driven automatic operation.

Final as-
sembly kit instructions, connection
diagrams in the appendix.
The 230 V AC input of the RLS 45 K per
-
mits operation with an additional function by
means of switching (with switch, button).
When additional functions are switched on,
the “Demand-driven operation” LED flashes.
Select one of the following
additional func-
tions
in service mode:
● Sleep mode
●
Intermittent ventilation
● Safety function (External OFF)
● Supply air operation with overrun time of
0 min.
● Supply air operation with overrun time of
6 min.
● Supply air operation with overrun time of
15 min.
The function of the 230 V input is only ever
taken into account on the directly controlled
RLS 45 K control. Additional room air controls
continue to run in the previous ventilation
level. The LED indicator for the automatic
function flashes slowly.
Exception:
The safety function
(External
OFF) impacts on all the ventilation system’s
room air controls. If this is triggered, all the
system’s ventilation units switch off regardless
of the control/power unit to which they are
connected.
Sleep mode function
(time-limited switch-off)
Sleep mode with ventilation level 0:
Function only with RLS 45 K/DS 45 RC
Sleep mode function possible in every
operating mode. Press key for 2 se-
conds – the
LED flashes slowly.
On RC units, all 3 LEDs light up and
then go out one after another.
Operating time of 60 minutes
. Can also be
set to a time of between 15 and 120 minutes
with the commissioning software. Once this
time has elapsed, the ventilation unit switches
back to the previously used ventilation level.
To
cancel,
press a button.
External switching on the 230 V input of
the RLS 45 K control is also possible with a
button.
Intermittent ventilation function
(time-limited intensive ventilation)
Intermittent ventilation with ventilation
level 5: Function only with RLS 45 K/
DS 45 RC
Intermittent ventilation is possible in
any operating mode. Press key for
2 seconds – the
LED flashes
slowly. On RC units, the current ope-
rating mode LED flashes twice, 5 times.
Operating time of 30 minutes
. Can also be
set to a time of between 5 and 90 minutes
with the commissioning software. Once this
time has elapsed, the ventilation unit switches
back to the previously used ventilation level.
To
cancel,
press a button.
External switching on the 230 V input of
the RLS 45 K control is also possible with a
button.
External OFF function
This function can be used to switch off all the
ventilation system’s ventilation units.
