Adjustment device type GUIV3-M (order code AT-VAV-G3)
VAV terminal units control the volume flow in a closed loop, i.e. measurement - comparison - correction. This is done via a differential pressure sensor. An integral differential pressure transducer converts the effective pressure into a voltage signal. The factory setting is such that 10 V DC correspond to the nominal volume flow rate (qvnom). The volume flow rate setpoint value defaults from a higher-level controller (e.g. room temperature controller, air quality controller, central BMS). 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.

Interface configuration of the control component
Depending on the setting, the Modbus communication interface or the analogue interface for the setpoint value specification of volume flows are available here. The so-called interface mode is preset at the factory according to the order key and can be adjusted on site by setting via the menu navigation or the Modbus registers.
,Typical interface configuration
XS0 | Setpoint value default setting via: | Actual values via: | corresponds to order key option | Menu configuration (Mode) |
Analogue operation | analogue 0 - 10 V | analogue 0 - 10 V | V or F | CA0 |
Analogue operation | analogue 2 - 10 V | analogue 2 - 10 V | V or F | CA2 |
Modbus operation | Modbus register setpoint | Modbus register actual value or analogue 2 - 10 V | M | CB |
Through special configuration of the Modbus register Interface-Mode, mixed operations of Modbus and analogue operation can be configured. See the description of the interface mode in Modbus register 122.
Supplementary use of the Modbus interface in analogue mode
In analogue mode, only the setpoints at the analogue input are evaluated by the controller. A setpoint specification via the Modbus interface (register 0) is not possible. Any write attempts are acknowledged with an error response. Regardless of the selected interface configuration, however, the other Modbus registers can be used. In this way, the operating values of the actual volume flow rate and damper position can be read out from a higher-level building management system (BMS) with local control using an analogue signal via a connected Modbus, or central override controls can also be triggered.

Use and description of the display
Pressing the LED button (< 3 s) selects the next menu item (1) - (6). The selected menu item can be changed by pressing the LED push button for more than 3 s. Changing is done with the rotary selector switch. Pressing the LED push button again (< 3 s) confirms the selected value. If no entry is made for ≥ 60 s, the system returns to menu item 1.
