The Primair Controller is an indoor climate controller, designed to be used with extraction & intake fans, it will maintain temperature in an indoor growing environment through the use of a thermostat.  The Primair Controller is also fitted with a speed control mechanism that will control the speed of two fans.

The Primair Controller works simply by wiring both your inlet and exhaust fans into the unit and setting the desired temperature.  Once the fans are wired in you can then set the speed control mechanisms to give you even more control over your environment & fine tune the climate controller to your own specifications.

The fan runs at max speed when it gets too hot and the variable controls the off settings independently for each fan.
