AHU Controllers | PDS2-V Ventilation and Temperature Controller

PDS2-V Ventilation Controllers are used to control ventilation plants. The controller can operate in constant discharge mode or reset control can be used to reset the supply air setpoint with the extract/room air temperature. The supply air flow has minimum and maximum temperature setpoints. PDS2-V can also be used in generic temperature control applications e.g. in hot water temperature control.. The controller is DIN-rail mounted and compact in design with built-in LCD and touch sensitive buttons for set up. LCD display shows in the user mode the temperatures and control valve position. The readings are automatically rotated for ease of view.

PDS2-V controller is configured using the LCD display and touch sensitive buttons. In the programming mode parameters such as the reset ratio and minimum and maximum temperatures can be configured. The configuration is easy using an intuitive menu structure.

PDS2-H controllers can be used with PT1000 sensors. The control valve can be 0..10Vdc, thermic (pulse width modulation) or 3-point 24Vac (switching to 0V).

PDS2-V has built-in Modbus RTU communication that can used to connect the controller to building management systems or the PDS2-V can be used with WebBiter Web-Browser interface. Using WebBiter all plant parameters are available for display and analysis via a standard web-browser.
