tems allows the use of the Easy controller in the supply air without additional dust protection measures.

 Extract air area of application:

– Extract air with a low content of dust or lint (e. g.

office) allows the use of the Easy controller without additional dust protection measures.

– For dry extract air with a higher proportion of

dust or lint, a suitable filter must be used in front of the VAV terminal unit.

– For extract air with a high content of dust, lint or

sticky components, or extract air with aggressive operating fluids, use a controller with a static differential pressure transducer, e. g. TROX Compact controller.

– In kitchen air extract systems, a VAV terminal

unit may only be used if it has been ensured that the extract air is cleaned as well as possible by highly effective aerosol separators, observe VDI 2052.

In unspecified applications, or when combined with polluted air (e. differential pressure transmitter should be used, e. g. TROX Compact controller or universal controller.

3.4 Function description

Basic function

The Easy controller is an electronic control component for variable volume flow control for various TROX V terminal units. Its functional units consist of a dynamic differential pressure transducer, the controller electronics and the actuator.

Closed control circuit

The controller operates in closed loop, i.e. to measure – compare – control.

The determination of the current volume flow rate takes place by measuring a differential pressure (effective pressure). For this purpose, the volume flow controller has a differential pressure sensor. The effective pressure is forwarded through the measuring hoses or, in the case of TVE, through the damper blade shaft to the differential pressure transducer integrated in the control component and converted here into a voltage signal.

The volume flow rate actual value is thus the internal control loop as well as an external use, e. g. BMS or master-slave sequential circuit, available as analogue voltage signal 0‑10 V. Due to the factory adjustment, the maximum output value of 10 V DC always corresponds to the nominal volume flow rate (V nominal) which can be taken from the scale sticker and the adjustments sticker on the VAV terminal unit.

The nominal volume flow rate is either set as a constant value or specified by an analogue voltage signal at the setpoint value input. The definition of the constant volume flow rates or of the working range for variable operation is carried out by the customer at the setting potentiometers V

In regular operation, the integrated actuator is controlled by permanent evaluation of the offset (setpoint valueactual) that adjusts the damper blade of the air terminal unit via the axle mounting and thus regulates the volume flow rate to the setpoint value.

Structure and functional description

Operating modes > Operation with constant volume flow rate setpoint value

Setpoint value adjustment independent of the duct pressure

Fig. 6: Pressure independent control characteristics

The controller detects and corrects changes of the duct pressure that may occur flow rate changes from other units. The Easy controller thus operates duct pressure independently and pressure fluctuations result in no permanent changes in volume flow rate.

In order to prevent the volume flow control from becoming unstable, the controller maintains a dead band (hysteresis) within which the damper blade is not moved. This dead band and the tolerances of the measurement location lead to a volume flow rate deviation ΔV in accordance with the product data sheets of the VAV terminal units. If the conditions specified in the product data sheets (e. g. minimum differential pressure, upstream conditions) are not met, greater deviations are to be expected.

Diagnostic options

A function test is possible by means of test push button (Fig. 1/8) and LED indicator light (Fig. 1/9). The LED makes it possible to distinguish between operating and fault states.

The diagnosis of setpoint value and actual value signals is possible via multimeter,

timeters to control setpoint values and feedback signals’ on page 29.

For the use of more variable volume flow rate setpoint values, the specification of an electrical control signal must be made by a higher-level controller (i. e., room temperature controller, air quality controller, central building management system, etc.). If the input signal is changed, the controller adjusts the volume flow rate to the new setpoint. The variable volume flow rate is limited to a minimum and maximum volume flow rate

In individual rooms and closed-off office areas, where the balance between supply and extract air flow rate has to be maintained. Otherwise, annoying whistling noises can occur at door gaps, and the doors can be dif this reason, the extract air should also have variable control in a VAV system.

The control signal from the room temperature controller is switched to the supply air controller in this example. The actual value signal of the Easy controller for the supply air is then applied as a setpoint signal for the Easy controller on the extract air (slave controller). As a consequence, the extract air always follows the supply air.

The scale sticker serves as an aid for setting the volume flow control range. The scale is individual for the combination of control unit, nominal size and mounted control component.

The grey shaded percentages (1 and 5) document the usable control range of the respective V The right edge of the scale at 100% documents the respective nominal volume flow rate in [m³/h], [l/s] and [cfm].

The percentages thus represent the ratio of the respective volume flow rate to the nominal volume flow rate.

Troubleshooting

Common mistakes > Deviation between setpoint value and actual value signal

7 Troubleshooting

olume flow rate controllers with Easy controller are

V tested technically before delivery. Operating parameters must be set individually for each controller during commissioning to the required system conditions.

If faults occur after commissioning, they can usually be remedied yourself using the following descriptions.

If a fault cannot be remedied on its own, TROX Service will be happy to assist you with troubleshooting, simply contact

For this, the following information is needed:

 Type and nominal size of VAV terminal unit (see

 Vmin/Vmax settings  Control input signal

7.1 Common mistakes

7.1.1

If the desired volume flow rate value is not adhered to precisely enough, which is the most frequent cause of error, this creates an unfavourable installation situation of the VAV terminal unit.

If the straight inflow length upstream of the volume flow controller is too short, the airflow becomes turbulent and the measurement of the volume flow rate becomes inaccurate. This is especially true when installing behind sharp edged bridges, fittings or junctions. The necessary straight inflow lengths are specified in the installation and commissioning instructions of the VAV terminal unit.

7.1.2 Incorrect wiring

In many cases wiring errors are the cause of faults. For this reason, only the 24 V supply voltage should initially be connected when troubleshooting an volume flow controller.

1. If present, disconnect the connecting cables at the

2. Check if the 24 V supply voltage is switched on.

3. Check whether the controller has reached the set-

When the supply voltage is switched on, the

values by adjusting the V

min

7.1.3 System pressure too low

The aim of the volume flow control is to regulate the volume flow rate actual value to the specified setpoint value.

For this purpose, a larger volume flow rate is required in the duct, which can be controlled (throttled) with the controller to the desired setpoint value.

If the volume flow rate in front of the control unit is too low (required minimum differential pressure not available), the setpoint value cannot be reached.

This can be detected on the damper blade shaft of the VAV terminal unit.

If the damper blade is still in the OPEN position with the setpoint signal present, instead of in a control position (throttle position), the volume flow rate is not high enough to set the setpoint value. The controller will try to open the damper blade further to reach the desired volume flow rate setpoint value.

7.1.4 Use outside the control area

If the device-specific control range is left with the potentiometer setting V

signal, the setpoint values cannot be reached. The actual value reached by the controller is undefined.

Potentiometer adjustment and setpoint value control signal:

Depending on the control unit type, the voltage signal must be >1V or 2V, in particular, when setting V

and V range.

7.1.5 Deviation between setpoint value

and actual value signal

Frequently the same signal voltage is expected at the setpoint value input and the actual value output. However, this only applies in the event that a V

100% are set on the potentiometers, since the same characteristic curve vertices are used for the setpoint value input and the actual value output.

Furthermore, in the controlled state, due to the permissible control tolerance, small deviations between the signal voltages of the setpoint value and actual value can always be expected.

Troubleshooting

Common mistakes > Deviation between setpoint value and actual value signal

If the potentiometer settings for V

and V

min

restrict the

max

usable control range, this will change the characteristic curve of the setpoint signal. Since the actual value signal is always assigned to a characteristic curve of 0 V

, a restriction of the usable control range results in a

nom

ferent characteristic curve for setpoint value and

dif actual value signal.

In this case, a direct inference due to different signal voltages at the setpoint value input or actual value output without (rollover) calculation is not possible.

7.3.2 Use of adjustment devices

The use of an adjustment device is not permitted for the Easy controllers. Depending on the delivery period and factory preparation, the values displayed on the control component cannot be clearly assigned as for the original equipment or for substitute controllers.

7.3.3

The adjustments sticker documents the factory testing, the settings and the most important order data of the VAV terminal unit and the control component.

Fig. 23: Adjustments sticker

The information is required as part of the technical support provided by the TROX service or for the ordering of replacement parts.

7.3.4

When ordering an Easy replacement controller, the device type and nominal size/dimensions are required when ordering. Customer-specific operating values for Easy controllers are not set at the factory. The information can be found, for example, in the adjustments sticker described in the previous chapter.

Example of order information: replacement controller type Easy for VAV terminal unit TZ-SILENZIO in dimension 200: TZ-SILENZIO 200/Easy

Note: for some VAV terminal unit types, Easy replacement controllers can be used regardless of the dimensions of the basic units.

This only applies to types TVR, TVJ, TVT and TVZ.

Examples: a replacement controller for the TVJ/Easy type can be used both on the nominal width of 300x100 and on all other dimensions of the TVJ. A TVR/Easy replacement controller can be used on the 250, as well as all other dimensions of the TVR.
