If only 1 fan can be controlled by the controller, then why does it have 1 hole for the temp and humidity sensor, and 2 holes called 1 & 2 for the controller cable?

Answer This Question

The controller has two ports and can control a maximum of two fans. If you need to control more, you will need to rewire.
