The 6 Stage Ventilation controller allows for a couple of variable outputs (such as variable fans). These variable outputs require a variable speed module to accompany the controller. Otherwise the 6 Stage Ventilation Controller's functions are similar to that of the 2 and 4 Zone Ventilation controllers. Please note that this product requires a 12V AC power supply. It cannot be powered with DC.
The 10 Stage 2 Zone Controller is a higher-end and highly reliable controller capable of handling larger systems requirements that go beyond what the 2, 4 and 6 stage controllers can do. This product has an additional user-friendly screen to display more information than other controllers.
The Touch Screen Ventilation TS32 controller worries about the management of an entire barn so you don’t have to. It is capable of continuously controlling barn temperature, CO2, feeding, water, alarms, etc.
