WARNING
!
Danger of electric shock from installing
the RLS 45 O and RLS 45 K inside the pro-
tective zone. No IP protection present
(IP 00). The room air control may only be
installed outside protective zones 0, 1 or 2.
When wiring several ventilation units,
i
always use a deep/double recessed-
mounted box (recessed-mounted box
provided by customer).
Strip wires of connection cables suffi-
i
ciently.
9.7 Connecting room air controls
RLS 45 O and RLS 45 K controls
i
with 230 V. Note safety requirements
in Chapter 9.6.
Wired systems
An RLS 45 O or RLS 45 K master room air
control can have a maximum of 3 further
power units and/or slave room air controls of
a similar design added to it.
A maximum of 4 control units can therefore be
deployed in this ventilation system.
You can only combine room air con-
i
trols of the same type (either RLS 45 O
or RLS 45 K).
The RLS 45 K controls and all other room air
controls/power units are connected via the
RS 485 interface.
If further room air controls are connect-
i
ed, these must be defined as slaves in
service mode Operating instructions
or commissioning instructions.
The relevant ventilation units are connected to
the relevant room air controls. The ventilation
units on an RLS 45 O/K are generally con-
nected directly to the Fan1 and Fan2 terminal
block.

Radio-controlled systems with PP 45 K
control and PP 45 EO radio module
External radio sensors and PP 45 RC units
can be connected to the PPB 30 K with these
unit combinations.
Connections
For possible combinations Chapter 7.
To install the room air control, we always
recommend using a deep recessed-mounted
box. If connecting more than 2 units, we
recommend wiring in another recessed-
mounted box.
PPB 30 ventilation units are not suita-
i
ble for use with PP 45 LT power units.
Connecting RLS 45 O
RLS 45 O room air control is used to activate
PPB 30 O units.
1. Take off frame of room air control.
2. Connect the PPBs according to the wiring
diagram ( Appendix).
The exhaust air function is only possi-
i
ble if a PPB 30 O is connected (service
mode setting for unit type = PPB 30 O
and number of units = 1).
3. Insert room air control in the re-
cessed-mounted box and screw down to
recessed-mounted box with 2 screws.
4. Fit frame. Ensure that the sensor opening
is above the PP 45 HYI (if fitted) and that
the frame engages.
5. Start up ventilation system Chapter 10.
