Setpoints and display
● Min. and max. limitation of room temperature setpoint:
– Comfort limitation (min. and max. limitation)
– Energy saving concept (min. and max. limitation separate for heating and cooling)
● Temporary Comfort mode extension
● Green leaf indication function
● Display of current room temperature or setpoint in ℃, ℉ or both
Setting
● Application selection via DIP switches or external commissioning software (ACS, ETS
and Siemens smartphone application PCT Go for Android™)
● Parameter download with external commissioning software (ACS, ETS and Siemens
smartphone application PCT Go for Android™)
● Reloading factory settings for commissioning and control parameters
Fan
● 1-speed, 3-speed or DC 0...10 V fan control on RDG200KN and RDG260KN (automatic
or manual fan)
● Advanced fan control function, e.g. fan kick, fan start delay, selectable fan operation
(enable, disable, depending on heating/cooling mode, or min. and max. speed setting)
● Fan start depending on fan coil temperature (heating) to avoid cool air while heating
● Enabling fan output only in the 2
nd
stage (2-pipe/2-stage)
● Switching fan speed from manual to automatic in the dead zone to avoid energy waste
(selectable function)
Special functions
● Swap function for 2-pipe and 2-stage application by switching the 1
st
stage heating to 2
nd
stage cooling
● On 2-pipe/2-stage application, limit the number of heating or cooling sequence to one
● Control of 6-port ball valve for chilled and heated ceiling, DC 0…10 V, DC 2…10 V and
inverted signals DC 10…0 V, DC 10…2 V (RDG260KN)
● Control of 6-port ball valve as changeover (On/Off – open/close signal) and PICV
DC 0…10 V for
– Chilled and heated ceiling/floor (RDG260KN)
– Fan coil application (RDG260KN)
● Control of 6-port ball valve via KNX S-Mode objects (RDG200KN and RDG260KN)
● Flow limitation function for PICV in heating mode (RDG260KN)
Inputs/outputs
● 3 multifunctional inputs selectable for:
– Window contact switches operating mode to Protection
