DIP NO.: 7…8 ➨ ON = , OFF =
Y1/Y3 = 2-position (PWM) 2-position (PWM) 3-position 3-position
Y2/Y4 = 2-position (PWM) 3-position 2-position (PWM) 3-position
● If 2-position (PWM) is selected via DIP switches, the control output is On/Off
(factory setting). To select PWM (pulse width modulation), set P201, P203
and/or P204 to 3.
● 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 or related
application configuration. Control outputs need to be set via tools in this case.
For details on connecting peripheral devices and setting of the DIP switches, refer
to the Mounting Instructions [➙ 5] [1] & [2]..
Applications with DC 0...10 V 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 P201 and/or P203 to 4 or DIP switch 7
and/or 8 to ON.
Example for 4-pipe application:
● Cooling: DC 0...10 V Y10 (P201 = 5, default), On/Off on Q1 (P201 = 4)
● Heating: DC 0...10 V Y20 (P203 = 5, default), On/Off on Q2 (P203 = 4)
When the RDG260KN is set for a chilled and heated ceiling with a 6-port ball valve,
the control output is Y10 and cannot be changed.
● Fan type can be selected via P351 or DIP switch 6, see Fan control [➙ 81]
● On RDG260KN On/Off valve actuator control on applications without fan
function – sequence of settings:
– Set DIP switch 6 to OFF and P351 to 3
– Disable the fan function by setting P350 to 0
– Set the valve actuators to On/Off by setting P201 and/or P203 to 4
● For commissioning via tools, set all DIP switches to OFF or related application
configuration. The control outputs need to be set via tools in this case
