I might be missing something, but i'm not sure what I would need that for? I don't plan on running a supplemental heater unless I find it necessary. The room stays at 70 empty during the winter months. With all the cages and racks in there that should raise the room temp up a degree or two. I have a 5,200 BTU window mount air conditioner that I will put in the room during the summer. It has built in digital temperature controls. The A/C unit will only be used to keep the room from getting too hot. Probably set it around 80 degrees.Originally Posted by tmlowe5704
