Technical data

The type of the control outputs (2- or 3-position) is set via DIP switches 4 and 5.
The patterns of DIP switches 4 and 5 are as follows:
ON
OFF
1 2

5
ON

1 2 3 4

• If 2-position is selected, the factory setting is On/Off. If you want PWM (pulse
width modulation), set parameters P46 and/or P47 to 2 = PWM.
• 4-pipe with electric heater: As the electric heater requires 1 of 4 outputs, only
the cooling valve actuator can be 3-position.
• For commissioning via tool, all DIP switches have to be set to OFF.
Control outputs need to be set via tool in this case.
For details concerning connection of peripheral devices and setting of the DIP
switches, refer to the Mounting Instructions M3191 [3].
Applications with DC 0...10 V (ECM) fan control (Y50) or without fan:
The type of valve actuator control outputs can be changed from DC 0...10 V
(factory setting) to On/Off.
To select On/Off valve actuator control, set parameters P46 and/or P47 = 1.
Cooling: DC 0...10 V Y10 (P46 = 2, default), On/Off on Q1 (P46 = 1)
Heating: DC 0...10 V Y20 (P47 = 2, default), On/Off on Q2 (P47 = 1)
• For applications with 3-speed fan, only DC 0...10 V control outputs Y10, Y20
are available.
• Type of fan can be selected via P53 or DIP switch 4, see section 3.8.
• On/Off valve actuator control on applications without fan function – sequence of
settings:
– Set DIP 4 to Off and P53 = 3.
– Disable the fan function via parameter P52 = 0
– Set valve actuators to On/Off via P46 and/or P47 = 1
• For commissioning via tool, all DIP switches have to be set to OFF.
Control outputs need to be set via tool in this case.
