Grozone OB2V Output Box Dimmer Controller
Switching your centrifugal fan from the standard output to the optional OB2V output will improve the temperature stability in your grow room, reducing the stress on your plants and also the noise normally associated with fans. The OB2V works as a Grozone fan controller TV1 or TV2. Unlike the TV1 or TV2, the OB2V does not have any dials or temperature probe. The OB2V uses the SCC1 temperature dial and probe values to control the fan.
