Awesome, thank you. I ordered one of the RG-11 Rain Sensors which has a 24v 1A relay on it and am going to try that out as well. We have a door sensor attached to the site monitor now, could I use that to trigger the site monitor relay? To turn on some 24vdc LED lights inside the enclosure when the door opens?

You just run power from your power source into the 'c' terminal, and then from the 'n.o' terminal to the fan. Hook the black back to the power source. If you just want temperature control, there are two values you can set which say 'relay on above' and 'relay on below' which will allow you set the relay to turn on/off with temperature control. I'd just set 'relay on above' to something like '200', which means turn the fan on over 20*C (about room temperature). If this doesn't work, let me know and I'll get you the correct firmware for that (there was a bug which we fixed, but I'm not sure where it is in the whole release/shipping/on website process). -forrest On Wed, Apr 20, 2016 at 9:28 PM, Scott Vander Dussen <sc...@velociter.net<mailto:sc...@velociter.net>> wrote: Fiberglass enclosure Bud Industries IPV-1116<http://www.alliedelec.com/bud-industries-ipv-1116/70368864/> vents Orion WMG60M<http://www.alliedelec.com/orion-knight-electronics-inc-wmg60m/70103693/> wire filters 60mm DC fan<http://www.rpelectronics.com/cfa246025ms-24vdc-sleeve-bearing-60mm-fan.html> with Locked Rotor Alarm Signal Output 60mm guard<http://www.rpelectronics.com/cfg-60m-60mm-metal-finger-guard.html> The enclosure includes a Site Monitor, I'm hoping to use its secondary DC input to monitor the fan's yellow alarm wire lead and trigger an error state in our SNMP monitoring if a fan becomes locked. I'm concerned about the fans running 24x7 potentially bringing in moisture from fog/nightly humidity. With the site monitor could to turn the fans on/off based upon ambient temperature or time of day? If yes, how would I do that, a relay? What kind of relay? I don't have much experience with relays/Site Monitors, thanks. Or is there some other obvious solution I'm missing? Another idea is to use a Hyderon RG-11 Rain Sensor / Gauge<http://rainsensors.com/how-it-works/> to trigger the fans off for both dark (less than 2000 lux) and/or rain. This seems pretty rad!
