Description
of functions
Basic functions
PID control for supply VAV and temperature
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 via the room operator unit.
The operating modes are Comfort, Pre-Comfort,
Economy and Protection.
The air flow for heating is operated in sequence to the
valves or electric reheater. Parallel operation can be
configured.
Extract air control by 0…10 V VAV compact controller.
Heating coil 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
PID control for air quality
Rapid ventilation.
Air volume flow tracking for positive and negative room
air pressure.
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.
Presence can be detected by binary sensor.
