The G.A.S Pro Step Controller – 4 Amp is an effective fan controller that eliminates one of the downfalls of AC fan control. The humming and buzzing. Many other fan controllers adjust the fan speed using technology that causes these noises and it can be very irritating. This is especially true in domestic situations at night time. The Pro Step Controller uses solid state relays with digital technology to create a top quality 5 step controller. Humming and buzzing is completely eliminated, even when the fans are running at slow speeds. There is also no clicking between the speed steps.
The dials on the front of the unit allow you to set maximum and minimum fan speeds in denominations of voltage to the fan. At 230v, the fan is at full speed with the lower voltages signifying slower speeds. The third dial is for setting the temperature you want the unit to maintain. Ideally, the probe should be in the middle of the room to get a good average room temperature.
As the name implies, the maximum load for the unit is 4 amps. This is great for small to medium size AC fans but may not be enough if you have bigger fans. There is also an 8 amp version for more larger scale applications.
