What are you supposed to have fans with 2 wires or fans with 3 wires. If you have 2 wires can you manually adjust each fan with a keypad button?

basically what is the whole deal with 2 and 3 wire fans.

thanks!

Hi ghost2501,

The difference in the 2 vs 3 wired fans is this, the third wire is RPM reading from the fan. If your fan has the third wire, the display can read how fast the fan is rotating. Some fans have this, some don't.Both 2 and 3 pin fans can be adjusted by the keypad, they are the same except for the RPM reading. If there is anything else, don't be afraid to ask.
