Description
of functions
Basic functions Options
∂ PID control for heating and cooling.
∂ 6-way valves 0...10 V controlled by analog outputs for
heating and cooling.
∂ The temperature is measured in the room operator
unit.
∂ The application allows customers to adjust the room
temperature setpoints via the room operator unit.
∂ The operating modes are Comfort, Pre-Comfort,
Economy and Protection.
∂ Change of operating mode via room unit, presence
detector, window contact or central command.
∂ 2
nd
passive chilled/heating beam.
∂ Condensation monitoring.
∂ Optimal energy efficiency by presence detector or
window contact.
∂ Optional system alarms displayed on the
management
station notify building operators of possible faults.
∂ Optional trends can be activated for room sensors.
Auxiliary functions Variants
∂ Green Leaf (RoomOptiControl) function.
∂ Multisegment use of DXR2 automation stations.
∂ 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.
∂ Central override functions for valves.
∂ Seasonal compensation of room temperature
setpoints.
∂ 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
∂ Presence can be detected by KNX PL-Link sensor or
binary sensor.
