All of our fans in our boxes are temperature controlled 24VDC fans using the relay on the site monitor. It works great! In 'Analog I/O' just set Relay on above 300 for 30 degrees celcius, or whatever temp you want. 20 degrees will run constant in our boxes. At least around here, even 300 runs almost constant during the summer. I used to run a separate cable from the power source to the 'C' or common point on the site monitor relay, but now I just add a jumper from the positive input on 'power 1' (site monitor's power source) to C, then connect the fan to NO.
