Application

Application

• Electronic volume flow controllers of Type Universal (static) are designed for use with VAV terminal units.
• Volume flow control or differential pressure control based on static differential pressure measurement
• Dynamic differential pressure transducer and electronic controller can be fitted together in one casing or in separate casings
• Actuator or spring return actuator is separate
• The output signals of the room temperature controller, central BMS, air quality controller or similar units control the volume flow rate setpoint
• Override control by means of switches or relays
• Volume flow rate actual value or differential pressure actual value is available as linear voltage signal
• Controller parameters are factory set
• On-site adjusting is not required
• Please note that in critical cases, material compatibility testing must be carried out on the air terminal unit and the differential pressure transducer, taking into consideration the harmful substances involved and the concentrations in which they occur.

Description

Parts and characteristics

• Sensor for static differential pressure measurements
• Separate actuator
• Mechanical stops for limiting the damper blade positions
• Actuators with overload protection
• Release button to allow for manual operation

Maintenance

• Zero point correction of the static differential pressure transducer should be carried out once per year (recommendation)
