Pressure measurement The integrated D3 differential pressure sensor is also suitable for very small volumetric flows. The maintenance-free sensor technology enables versatile applications in the comfort zone: in residential construction, offices, hospitals, hotels, cruise ships, etc.. Actuator VAV unit manufacturers offer different actuator variants (rotary or linear actuator) for different VAV units structures. Control function Volumetric flow (VAV-CAV) or Open-Loop (for integration in an external VAV control loop). VAV – variable volumetric flow Demand-dependent setting of volumetric flows V min max on a modulating reference variable (0/2…10 V), e.g. room temperature / CO2 controller, DDC or Bus system, for energy-saving air conditioning in individual rooms or zones. CAV – constant volumetric flow Step mode (via switching contact) for constant volume applications CLOSED / V min / V max / OPEN. DCV – Demand Controlled Ventilation With DDC with integrated DCV logic Operating and service devices Service tool ZTH, PC-Tool service socket: locally pluggable Electrical connection The connection is made with the integrated connection cable.

If the required switching threshold of 0.1 V cannot be attained, the threshold can be switched to 0.5 V. Note on CAV application: the shut-off level must not be set to 0.5 V. If the line 3 (Y) is open, damper will be CLOSED instead, min will be activated. 3) within the mechanical limit. 4) The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. The actuator then moves into the required position in order to ensure the volumetric flow defined by the positioning signal. 5) See www.belimo.us for function and version history.
