A dynamic differential pressure transducer and electronic controller are combined in one housing. The principle requirements for variable volume flow control are a suitable room temperature controller or a DDC outstation or similar. The output signal from this controller serves as a command variable for the VRD2. Switches or relays are used for override control. The actual value of the volume flow is monitored as a standard linear, electrical signal. This signal can be used for example to control a slave unit in the extract air duct. The voltage range for the actual and control value is standardised between 2 and 10 VDC. Using the adjuster ZEV, the customer can change from 0 to 10 VDC. The VRD2 has adjustment knobs for setting V · min and V · max. All the controller parameters are set by Trox and the unit is supplied with the knobs sealed. No adjustment is necessary by the customer. As soon as the supply voltage and the room temperature controller have been connected, the volume flow control unit is ready for use. Any volume flow changes which may be necessary to the VRD2 can easily be carried out by the customer. For parallel operation, several VRD2 controllers can be connected up to one room temperature controller. Supply air/extract air slave control is possible. The VRD2 is capable of communication through the PP connection (terminal 5). With the aid of the Belimo adjuster ZEV, the parameter settings can be read and the voltage ranges changed. Standard filtration in air conditioning systems allows the use of the VRD2 in the supply air without dust protection filters. Since a small volume flow is passed through the transducer in order to monitor the volume flow, the following must be noted: • With heavy dust in the room, suitable extract air filters must be provided. • If the air is contaminated with fluff or sticky particles or contains aggressive media, the VRD2 should not be used.
