The controller will either open or close curtains or vents depending upon requirements from a connected thermostat or control input. Utilizing a built-in 5 minute timer the controller reacts to the thermostat/control input every 5 minutes whether to open or close ventilation.

Open and Close times of the curtain machine/actuator are adjustable using the two dial indicators inside the controller cabinet. Operation times are adjustable from 0.6 to 60 seconds.
