Primair Twin Fan Speed Controller

The Primair Twin Fan Speed Controller is a great piece of kit for maintaining your grow room temperatures, when it is connected to your inlet and outlet fans.

The Primair Twin Fan Speed Controller is a combined fan speed controller and thermostat. The unit is fitted with a cable which has a probe on the end to place into your growing area to read the temperatures. The temperature dial can be set to your required temperature you wish to maintain your grow room at and you can also set the idle speeds of both the inlet and outlet fan. As the temperature in your grow room rises above your set point the fans will both turn on to full speed to lower the temp back down again, once it is reached the fans will slow down to the idle speed you have set until the temp rises again, then it will repeat the process. This will maintain a much better temperature and atmosphere for your plants to flourish as there will be no major temperature fluctuations, which will lead to a better crop.


Top Tip
The Primair does require wiring and you will need electrical cable for your fans to connect to the unit and also some cable and a plug for the mains supply. It is supplied with full instructions, but if you are in any doubt, consult a qualified electrician first.
