Description
of functions
Basic functions Options
∂ PID control for supply air and temperature.
∂ 3-position damper controlled by triac outputs for VAV
control.
∂ Internal air flow controller controls damper actuator.
∂ The serial fan speed is controlled manual on the room
operator unit or automatic with variable speed.
∂ 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.
∂ The air flow for heating and cooling is operated in
sequence to the valves. Parallel operation can be
configured.
∂ 2-stage electric reheater.
∂ Parallel fan (supply air), modulating control.
∂ Optimal energy efficiency by including the option for
room/supply air cascade control, 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
∂ Air supply functions to coordinate demand signals for
pressure optimized fan control.
∂ Green Leaf (RoomOptiControl) function.
∂ Multisegment use of DXR2 automation stations with
FPB application.
∂ 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.
∂ Continuous damper controlled by 0…10 V analog
output for VAV control.
∂ VAV actuator on KNX PL-Link.
∂ 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
∂ Presence can be detected by KNX PL-Link sensor or
binary sensor.
