2.2 Description
The model A2G-100 PID controller is used for the control of dierential
pressures or air ows in ventilation and air-conditioning applications.
The 0 ... 10 V or 4 ... 20 mA control output is connected as control signal
directly to the EC ventilation fan or frequency inverter (FI). Its two-line
LC display simultaneously shows the direction of the monitoring output
and the current measured value. It provides analogue electrical output
signals of 0 ... 10 V or 4 ... 20 mA, which can be set by the operator via a
jumper within the instrument.

3.2 Intended use
The A2G-100 is a multi-functional PID controller for dierential pressure
or air ow control, specically developed for the demands of the
air-conditioning and ventilation industry.
This PID controller enables a continuous pressure control or air ow
control for EC fans, variable air volume systems (VAV systems) or
ventilation aps.
This instrument is not permitted to be used in hazardous areas!
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
