Description
of functions
Basic functions
PID control for supply VAV, temperature and air
quality.
Supply air differential pressure control sensor
integrated in controller.
Internal air flow controller controls supply air damper
actuator (integrated in controller).
The application allows customers to adjust the room
temperature setpoints and rapid ventilation via the
room operator unit.
Display of room air quality on room unit.
The operating modes are Comfort, Pre-Comfort,
Economy and Protection.
The air flow for heating and cooling is operated in
sequence to the valves or electric reheater. Parallel
operation can be configured.
Extract air control by either 0…10 V or KNX PL-Link
VAV compact controller.
Heating and cooling coils with 3-position valves
controlled by triac outputs
Optimal energy efficiency by including the option for
room/supply air cascade control, presence detector or
window contact.
Auxiliary functions
Rapid ventilation.
Air volume flow tracking for positive and negative room
air pressure.
Green Leaf (RoomOptiControl) function.
The application allows 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.
0…10 V output can be selected for valves.
Room operator unit and sensor variants:
o KNX PL-Link wall-mount sensor
o KNX PL-Link wall-mount room operator unit
o KNX PL-Link flush-mount sensors
o Analog extract air temperature sensor
Presence can be detected by KNX PL-Link sensor or
binary sensor.
