1. Room controller: 0…8; Room unit: 0…10
2. The setpoint cannot be changed in ECO mode.

Restriction for sensor selection:

1. If SEN1 and SEN2 are configured with the same selection type 1…8, they cannot be the same sensor types:
   • For type 1…8, sensor1 cannot be the same as sensor2.
   • For sensor types with the same function such as 1&2 or 5&6, if one sensor type is 1 or 5, the other one cannot be 2 or 6.

Firmware Setpoint Settings

PM2.5 SP	PM2.5 setpoint	SPML…SPMH	60
CO2 SP	CO2 setpoint	SPCL…SPCH	1000

VOC SP	VOC setpoint	%: 0…100 mg/m3: 0…5	0.6 mg/m3 or 6 %
HUM SP	Humidity setpoint	0…100 %	50 %
P81 1)	Device address (KNX only)	1…255	255

1) P81 is only for ETS and local HMI does not support P81:

• During power up, there is a startup delay (TwaitDevice = tWaitMin + DeviceAdr * 200ms) before the processing signal is processed.
• When P81=255(default), the device does not process the signal according to the heartbeat and COV mechanism. But it can respond when another device is polling.
• The local HMI does not support P81.
• When the individual address is changed via ETS, P81 is updated automatically after the device downloads it from ETS.
