The relay on the base unit is more than large enough to turn on and off that fan - at 24V it can switch 2A. 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 <[email protected]> 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.
