I removed the housing so it would run cooler. One time it blew the internal fuse because of heat build up. I removed the housing and it has not happened since. It kept my 535 gal + 150gal in the sump steady @ 79 degrees. I was running 3 400w and 3 250w halides over the tank! I now have a 325 gal tank, switched to LEDs and the chiller has not come on since.
This unit is accurate and works perfect, just a little dirty.
New these are now around $1200
$400 obo
Thanks
