<p dir="ltr">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. </p>

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
<a href="http://www.zephyrvent.com" target="_blank">www.zephyrvent.com</a>; that's what we're addressing.<br>

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<u></u><u></u></span></p>
