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 q_vmin, q_vmax, 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

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

  <strong>Principle of operation – LVC, TVR, TZ-Silenzio, TA-Silenzio, TVZ, TVA, TVJ, TVT</strong>

① Effective pressure transducer

② Actuator

③ Volume flow controller

④ Setpoint value signal

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 (q_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 q_vmin and q_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.
Flow rate parameter q_vmin and q_vmax can be set on potentiometers.

Category

Type Easy volume flow rate controller with potentiometers to set q_vmin, q_vmax

Application

Control of a constant or variable volume flow rate setpoint.
Electronic controller for applying a reference value and capturing an actual value signal.

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
