Auxiliary functions
Variants
• Green Leaf (RoomOptiControl) function.
• Multisegment use of DXR2 automation stations with
fan coil unit application.
• Standard hot water supply chain control.
• The application allows for control via centralized
commands (e.g. scheduler program for room operating
mode).
• Central optimum start control provides best room
comfort at the start of occupancy.
• Central operation or reset of setpoints, timed valve
kick function or outside temperature dependent
heating limit.
• Central override functions for valves.
• Seasonal compensation of room temperature
setpoints.
• 1…3 speed.
• PWM constant (incl. spring return) or PWM thermal
control can be selected for valves.
• The room temperature can be measured by:
o KNX PL-Link wall-mount sensor
o KNX PL-Link flush-mount room operator unit
o KNX PL-Link flush-mount sensors
o Analog extract air temperature sensor
• KNX PL-Link switches for lighting and blinds
operation.
• Presence can be detected by KNX PL-Link sensor
or binary sensor.
Lighting
• The application allows for control via centralized
commands (e.g. scheduler program).
• The application function supports runtime totalization
for each lighting group for maintenance and service
purposes (burn in/operation h/ EOL end of life cycle).
Blinds
• The application allows for control via centralized
commands (e.g. scheduler program or weather
station).
