EASY

For easy adjustment


Control components for VAV terminal units, to be mounted on the terminal unit for easy operation

 

  • Simplified ordering and on-site assignment to rooms as selection is based on the nominal size of the duct
  • Simple volume flow rate setting without additional device
  • Indicator light simplifies functional checking
  • With push button for triggering a function test
  • Proven technology of the Compact volume flow controllers
  • Suitable for constant and variable volume flow rates and qvmin-, qvmax-Switching

General Information


Application

  • All-in-one control devices for VAV terminal units
  • Dynamic effective pressure transducer, electronic controller and actuator are fitted together in one casing
  • For use with clean air only
  • Standard filtration in comfort conditioning systems allows for use of the controller in the supply air without additional dust protection
  • Choice of various control options based on setpoint value default setting
  • Volume flow rate control is based on setpoint values received from room temperature controller, central BMS, air quality controller or other devices as an analogue signal.
  • Override control for activating qvmin, qvmax, shut-off or OPEN position can be set with a switch or relay
  • The volume flow rate actual value is available as a linear voltage signal

 

With heavy dust levels in the room

  • Install suitable extract air filters upstream, as a partial volume flow is routed through the transducer for volume flow rate measurement

 

If the air is contaminated with fluff, sticky components or aggressive substances

  • Do not use an Easy controller




Construction


  • LMV-D3AL-F TR for LVC
  • TR0VE-024T-05I-DD15 for TVE
  • LMV-D3A-F TR for TVR
  • LMV-D3A TR for TZ-Silenzio, TA-Silenzio, TVZ, TVA

  • 227V-024T-15-002 for TVJ, TVT up to 1000 x 600
  • SMV-D3A TR for TVT from 1000 x 600




Parts and characteristics

  • Transducer for dynamic measurements
  • Mechanical stops for limiting the damper blade positions (not for TVE)
  • Actuators with overload protection
  • Transparent protective cap or terminal cover (TVE)



Interface



  • Analogue signal 0 – 10 V DC



Control strategy



  • 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



Operating modes



  • Operating mode variable volume flow rate, qvmin: Minimum volume flow rate, qvmax: Maximum volume flow rate
  • Operating mode Constant value, qvmin: Constant volume flow rate, qvmax: 100 %



Commissioning



  • Operating values qvmin, qvmax to be set on site with potentiometer on the outside of the housing without additional adjustment tools

  • Function
  • SPECIFICATION TEXT
  • ORDER CODE

A closed control circuit for regulation of the volume flow rate, i.e. measuring - comparing - adjusting, is characteristic of air terminal units.
The volume flow rate is measured by measuring a differential pressure (effective pressure). This is done via a differential pressure sensor. An integrated differential pressure transducer converts 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 (qvnom).
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 qvmin and qvmax. 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.
Flow rate parameter qvmin and qvmax can be set on potentiometers.


Category

Type Easy volume flow rate controller with potentiometers to set qvmin, qvmax


Application



  • Control of a constant or variable volume flow rate setpoint.
  • Electronic controller for applying a reference value and capturing an actual value signal. 
  • The actual value signal relates to the nominal volume flow rate so that commissioning and subsequent adjustment are simplified
  • Stand-alone operation or integration with a central BMS.

Area of application

  • Dynamic transducer for clean air in ventilation and air conditioning systems


Actuator

  • Integral; slow running (running time 100 – 270s for 90°)


Installation orientation

  • Either direction



Connection


  • Double terminal for supply voltage to connect up to 3 controllers 
  • No junction box required.



Supply voltage


  • 24 V AC/DC



Interface/signalling


  • Analogue signal 0 – 10 V DC



Interface information


  • Volume flow rate setpoint value and actual value
  • The actual value signal relates to the nominal volume flow rate so that commissioning and subsequent adjustment are simplified



Special functions


  • Clearly visible external indicator light for signalling the functions: Set, not set, and power failure
  • Activation of Vmin, Vmax, Closed and Open, by means of external switch contacts



Parameter setting


  • Parameters specific to the VAV terminal unit are factory set
  • Vmin and Vmax can be set by others using the potentiometers on the outside of the casing, no tools required




Factory condition

  • Electronic controller is factory mounted on the control unit
  • Factory-set parameters
  • Functional test with air (see sticker)

Commissioning

  • Take the adjustment values from the volume flow rate scale (sticker on each VAV terminal unit)
  • Use the potentiometer to set the minimum or maximum volume flow rate on site
  • 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 control range TVE: 4 – 100%
  • 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 protective cap or terminal cover (TVE) of the Easy controller only temporarily for wiring and commissioning
