Description
of functions
Basic functions Options
HVAC
∂ PID control for heating and cooling.
∂ 3-position valves are controlled by triac outputs for
radiator heating and chilled ceiling 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
including the operation of lighting and blinds.
∂ 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.
HVAC
∂ 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.
Lighting
∂ The application allows room users to control lighting
via a standard function switching and/or
∂ The application allows customers to control lighting
operation via room unit.
Lighting
∂ Optional system alarms displayed on the
management station notify building operators of
possible faults (e.g. defective electronic control gear
or lamps).
∂ Optional trends can be activated for room lighting.
Blinds
∂ The application allows room users to operate the
blinds via the following commands:
o Move up/down
o Step up/down
∂ The reference model applied ensures exact
positioning of the shading products.
∂ The application allows customers to control shading
operation via room unit.
Blinds
∂ Optional system alarms displayed on the
management station notify building operators of
possible faults (e.g. defective actuator).
∂ Reliable, central override of local operation only for
emergencies, service, and cleaning.
∂ Central weather protection function preventing
damages to shading products due to high winds or
frost.
∂ Optional trends can be activated for room blinds.
Auxiliary functions Variants
∂ Green Leaf (RoomOptiControl) function.
∂ Multisegment use of DXR2 automation stations.
∂ 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.
∂ 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
∂ 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).
