Description

The model A2G-200 control panel with integrated room sensor was developed specifically for requirements in the ventilation and air-conditioning industry. Different versions measure the key parameters of relative humidity, room air temperature and carbon dioxide (CO₂).

The large touch LC display makes the operation and readability easy and clear. The integrated switching output enables a direct control command to higher-level systems or can be used for the direct switching on of a ventilation/air-conditioning unit or fan. For this, the switch relay can be configured with all three parameters (relative humidity, ambient air temperature and CO₂).

The measuring results are transmitted with an analogue output signal (0 ... 10 V or 4 ... 20 mA) or digitally via Modbus^® output.

To prevent incorrect operation or manipulation, the LC display can be locked via setting a jumper on the PCB and then only has the function of a display and measuring instrument.
