  • Application
  • Description

Application

  • Electronic volume flow controllers of Type Easy are compact, all-in-one control devices for VAV terminal units
  • Dynamic differential pressure transducer, electronic controller, and actuator are fitted together in one casing
  • Suitable for different control tasks depending on how the input for the setpoint value signal is used
  • 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 is available as linear voltage signal

Standard filtration in comfort air conditioning systems allows for use of the controller in the supply air without additional dust protection. Since a partial volume flow is passed through the transducer in order to measure the volume flow rate, please note:

  • With heavy dust levels in the room, suitable extract air filters must be provided.
  • If the air is polluted with fluff or sticky particles, or if it contains aggressive media, Easy controllers cannot be used

Functional description

VAV terminal units control the volume flow in a closed loop, i.e. measurement – comparison – control.

The volume flow rate is determined by measuring the differential pressure (effective pressure). For this purpose the VAV terminal unit is fitted with a differential pressure sensor.

The integral differental pressure transducer transforms the effective pressure into a voltage signal. The volume flow rate actual value is hence available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal volume flow rate (Vnom).

The volume flow rate setpoint value comes from a higher-level controller (e.g. room temperature controller, air quality controller, central BMS) or from switch contacts. Variable volume flow control results in a value between Vmin and Vmax. It is possible to override the room temperature control, e.g. by a complete shut-off of the duct.

The controller compares the volume flow rate setpoint value to the actual value and controls the integral actuator accordingly.

The volume flow rate parameters Vmin and Vmax can be set on potentiometers.

Volume flow control

  • The volume flow controller works independent of the duct pressure
  • Differential pressure fluctuations do not result in permanent volume flow rate changes
  • To prevent the control from becoming unstable, a dead band is allowed within which the damper blade does not move.
  • The factory set volume flow rate parameters can be altered by the customer

  • Inbetriebnahme

Commissioning

  • Use the potentiometer to set the minimum or maximum volume flow rate on site
  • Take the adjustment value from the volume flow rate scale (sticker on each VAV terminal unit)
  • Comply with the volume flow rate control range, do not set a volume flow rate which is below the minimum flow rate
  • Volume flow rate range of LVC, TVR, TZ-Silenzio, TA-Silenzio, TVZ and TVA: 10 – 100%
  • Volume flow rate range of TVJ and TVT: 20 – 100%
  • Once the VAV terminal unit has been installed and wired, and the volume flow rate has been set, the unit is ready for operation
  • Remove the transparent cover of the Easy controller only temporarily for wiring and commissioning
