Service mode setting parameters

For further information on functions and settings in the CDV commissioning software, see the RV 2 installation and commissioning instructions.

Factory settings for the following parameter setting values in bold.

Parameter 1: Unit type on RLS (Fan1, Fan2)

No function for RV 2.

Parameter 2: Number of unit pairs, unit types PP 45 and PPB 30 O

No function for RV 2.

Parameter 3: Deactivating ventilation level 0

 

1 = Ventilation level 0 activated.

2 = Ventilation level 0 deactivated. The ventilation units cannot be switched off on this control. The units run at least at level 1.

 

Parameter 4: LT power units, RLS 45 K room air controls (on the RS 485 bus)

 

Configuration for parallel operation of several LTs / RLS.

0 = no further LTs/RLS
1 = operation with 1 LT or RLS
2 = operation with 2 LTs or RLS
3 = operation with 3 LTs or RLS
4 = slave no. 1
5 = slave no. 2
6 = slave no. 3

Parameters for linking this room air control with other room air controls (RLS) or power units (LTs).
Example: Two further RLS (RLS #2 and #3) are connected to RLS #1.
Setting value at RLS #1 = 2 / Setting value at RLS #2 = 4 / Setting value at RLS #3 = 5.

 

Parameter 5: 230 VAC input

 

1 = Sleep mode
2 = Intermittent ventilation
3 = Safety shutdown

4 = Supply air mode without overrun, for volumetric flow compensation for exhaust air fans (ECA/ER (60m³/h))
5 = Supply air mode with overrun of 6 minutes
6 = Supply air mode with overrun of 15 minutes

4 to 6: Activate volumetric flow compensation using RV 2 units additionally via commissioning software.

230 V input with switching contact, additional function can be used with button or switch, see Connection and wiring diagram, "S1".

Recommendations: Use a button for the sleep mode and intermittent ventilation functions (reacts to falling edge).
Use a switch for functions 3 to 6 (reacts to switching status).

 

Parameter 6: Sensors

 

0 = No sensors
1 = 1x internal sensor, no external sensor
2 = 1x internal sensor, 1x external sensor
3 = 1x internal sensor, 2x external sensor
4 = 1x internal sensor, 3x external sensor
5 = 0x internal sensor, 1x external sensor
6 = 0x internal sensor, 2x external sensor
7 = 0x internal sensor, 3x external sensor

Parameters for using the connected internal and external sensors. The internal sensor PP 45 HYI and the external sensors PP 45 HY, PP 45 CO2 and PP 45VOCare available.

Parameter 7: EnOcean

 

For activating the EnOcean extension module PP 45 EO.

0 = EnOcean module not present
1 = Activate EnOcean module

 

Parameter 8: EnOcean Teach mode

No function for RV 2.

 

Parameter 9: Number of PPB 30 K units

No function for RV 2.

 

Parameter 10: ModBus settings

ATTENTION: The ModBus interface must be deactivated for RV 2 units, otherwise RV 2 units cannot be controlled.

 

Parameter 11: ModBus address

No function for RV 2.

 

Parameter 12: Plug & Play

 

Automatic search run for pairwise assignment of the supply air and exhaust air units.

0 = Manual settings with commissioning software

1 = Plug & Play: Start automatic search

Exit setting mode

Press the and buttons together for 5 seconds. The ventilation unit switches to the specified ventilation level.
