Interesting but the price puts higher than a Zephyr and a Solar
Converters Simple Switch, which is about the same thing with a backdraft
preventer.

If you do not have auxiliary relays to work with, try looking up
FumeOut by LSL Products. They make a nice vent fan with a dedicated
voltage controller. Only downside is it does not have a back draft
damper such as the zephyr does. But it uses 2" pvc so if you wanted to
get creative and make a back draft damper it wouldn't be so hard.

Gary,
No, the fan is turned on to forcibly exhaust gasses released by
charging, rather than based on temperature, so voltage-based
control is exactly what's desired. Take a look at
www.zephyrvent.com <http://www.zephyrvent.com>; that's what we're
addressing.

Hi Chris,
All the aux relays are voltage controlled so not sure what
setting you would use to activate the fan? I would assume you are
trying to turn the fan on based on high temperature in an
enclosure or something so battery voltage wouldn’t be a good
indicator. We have military and vehicle applications that use +12
or 24v to the fan via an adjustable t-stat. Check Grainger under
HVAC t-stats, this one is around $25
