System information for specialist installers

• System configuration in the service menu of the RLS 45 K control unit or with the commissioning software.
• The service menu of the RLS 45 K is used to set important unit functions or to register sensors, the EnOcean module or power units.
• When setting up the system, the Plug & Play function can be used with an even number of CPP 60 ventilation units, with which the ventilation units in the residential unit are automatically paired. Manual assignment is therefore not necessary.
• The commissioning software has an extended range of functions. Systems with an odd number of CPP 60 ventilation units or mixed systems with exhaust air units can also be configured here. If there is an uneven number of units (3, 5 or 7 ventilation units), the control system ensures volumetric flow compensation between the supply air and exhaust air units. No commissioning software is required for a mixed system with, for example, 2x PP 45 and 2x CPP 60 (PP 45 via Fan1/2 and CPP 60 via Plug&Play).
• External, wired sensors PP 45 HY, PP 45 CO2 or PP 45 VOC (air quality) provide the measurement data for the automatic function. These are connected to the RS 485 bus of the RLS 45 K control unit. 3 external sensors (also mixed) can be connected per RLS 45 K.
• Use the rotary switch on the sensor housing to address the sensors, see External sensors (HY, CO2, VOC):
  ● Position 0: Sensor 1
  ● Position 1: Sensor 2
  ● Position 2: Sensor 3
• In combination with an EnOcean wireless module PP 45 EO, radio sensors and radio switches can also be used. Up to 8 radio sensors can be taught to one master RLS. The sensor types must comply with the EEP protocol, see Teach-in radio components (EEP).
• The ventilation system can be expanded with up to 3 PP 45 LT power packs and 3 RLS 45 K control units (as slaves). Connection to the RS 485 bus of the master RLS.
• Several ventilation units can be connected to each PP 45 LT or RLS 45 K slave. The permissible number of units depends on the power consumption of the unit components and must be calculated, see chapter Mixed system with ER + 4 CPP 60 (unmixed)
• The power units and slave controls are activated in the service menu of the RLS 45 K or with the commissioning software.
• The 230 V input of the RLS 45 K control unit has a switching contact for the following additional functions (activation in the service menu):
  ● Sleep mode
  ● Intermittent ventilation
  ● Safety function (external OFF)
  ● Supply air mode with run-on time 0 min.
  ● Supply air mode with run-on time 6 min.
  ● Supply air mode with run-on time 15 min.
• A ModBus connection in combination with RV 2/CPP 60 ventilation units is not possible. The ModBus can only be used with single-variety PP 45 systems. For this purpose, the ModBus interface can be reconfigured and the RS 485 bus can no longer be used.
