Description
of functions
Basic functions
Options
• PID control for heating and cooling.
• 3-position valves are controlled by triac 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.
• Downdraft compensation.
• Outside temperature (for downdraft compensation)
distributed over BACnet.
• 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.
• 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
• Presence can be detected by KNX PL-Link sensor or
binary sensor.
