PP 45 RC service menu

LEDs		Parameters	Set value	Setting / description
	The orange operating mode LED flashes 1x per cycle	Supply air mode	0 1 2	Supply air mode without overrun Supply air mode with overrun of 6 min. (red LED 1x) Supply air mode with overrun of 15 min. (red LED 2x) Supply air mode for exhaust air units (e.g. ER.../ECA...) is released and parameterised here. Notice: The choice of overrun (6 or 15 minutes) depends on the unit. ER 60 (0 min.), ER 60 VZ (6 min.), ER 60 VZ 15 (15 min.).
	The orange operating mode LED flashes 2x per cycle	Sensor	0 1	Inactive active (red LED 1x) The PP 45 HYI internal humidity sensor is activated here. This sensor can be retrofitted as an option (only in master unit) and is not included in the scope of delivery.
	The orange operating mode LED flashes 3x per cycle	Ventilation levels	0 1	Ventilation level “0” possible Ventilation level “0” blocked (red LED 1x) If ventilation level “0” is set to blocked, the ventilation units cannot be switched off at this control. The units then run with at least ventilation level 1
	The blue operating mode LED flashes 1x per cycle	Duration of intermittent ventilation/ ventilation level	1 2 3	10 minutes (red LED 1x) 30 minutes (red LED 2x) 60 minutes (red LED 3x) The duration of the intermittent ventilation (level 5) and the duration of the ventilation level, when overriding the demand-driven operation, are parameterised here (factory setting 30 minutes)

LEDs		Parameters	Set value	Setting / description
	The blue operating mode LED flashes 2x per cycle	Sleep function	1 2 3	30 minutes (red LED 1x) 60 minutes (red LED 2x) 90 minutes (red LED 3x) The duration of the sleep function (level 0) is parameterised here (factory setting 60 minutes).
	The blue operating mode LED flashes 3x per cycle	Filter runtime	1 2 3 4	2 months (red LED 1x) 3 months (red LED 2x) 6 months (red LED 3x) Reset filter runtime (red LED 4x) .The filter runtime is parameterised here (factory setting 6 months).
	The blue operating mode LED flashes 4x per cycle	Single-room ventilation unit	1 2	Operation in pairs (red LED 1x) single-room ventilation unit (red LED 2x) The configuration of the PP 45 RC unit, as a single-room ventilation unit, is released here. Recommendation: PP 45 RC-Do not use units as single-room ventilation units, because the DIBt approval will thereby cease to apply. If a PP 45 RC is used as a single-room ventilation unit, the volumetric flow compensation must be undertaken using exterior wall air openings. This has a negative impact on the degree of heat provision.
