Vostermans Ventilation's ETD-C features a direct fan control system with climate control capabilities, via an on and off function. This apparatus also enables alarm and heater control. It features adjustable ventilation levels, an automatic cool-down correction mechanism, and a programmable 0 to 10-V output signal. Total current rate measures 10 Amps (applies for all relays). It also showcases an inlet signal component.
Added contacts are required for more extensive currents, and three-phase fan management.
