Interface module for GSD air heaters

With an Interface module you can control 1 to 8 G(N)SD or G(N)CD air heaters in, for example, a building management system by means of the following signals: heating, ventilating, high and/or reset. When an air heater is in malfunction or operation a notification is given by a potential free contact. All contacts are potential-free and the connected air heaters are controlled simultaneously.
