Volta - FAQ´s

How does the adaptation of the heating register output to a variable air volume work? Which components are required for this?

With variable air volume, the total output of all switching groups of an air heater must be reduced proportionally as one stage with a thyristor or power controller.

This requires a duct temperature sensor, a thyristor and a higher-level control.

The duct sensor measures the temperature according to the heating register and passes this signal on to the higher-level control.

The control processes the temperature signal and sends a 0-10V signal to the thyristor power controller.

The thyristor receives the 0-10V control signal and uses a pulse width modulation to vary the total output of all switching groups of the air heater as a step to the required level.
