4.7.9.1 Chilled/heated ceiling with 6-port control ball valve
(RDG260KN)
The RDG260KN is able to control a 6-port control ball valve for a chilled and
heated ceiling application.
This application is available, if the thermostats are set as 4-pipe with 6-port ball
valve applications (DIP4 = ON, see Applications for universal systems [➙ 42]).
Only one signal DC 0…10V (Y10 output) is used to control the 6-port control ball
valve for heating and cooling.
