Dave, I just pulled one of those out in a battery retrofit, I don't know what the customer did with it...
Maybe a Morningstar relay controller could be setup using system voltage?

Hi all,What are people using these days for venting a good ol' 48v flooded lead acid battery box? I am upgrading an off grid system. There is a one year old set of flooded lead acid batteries, so those will stay, but everything else will be new. I plan on using a Sol-Ark inverter. The existing battery box does not have any active ventilation, so I would like to add some. In the past, I have used the Zephyr Power Vent Fans, like this one:They don't seem readily available, but I think I can find one somewhere.More importantly, what would you use to control this? Sol-Ark inverters do not have any kind of relay for it. I have found external controllers in the past (Yandina LLC Vent Control), but I cannot seem to find any right now. There is one noted in the fan documentation (Solar Converters, Inc. VCS1AH), but that does not seem available anywhere right now. Does anyone have a recommendation for either a vent fa controller or a whole venting solution?Thanks!--
