Hello, just picked up these 2 AP cages. I received this herpstat II with it. When I go to site, the one on there is different. this only has 2 buttons. Does anyone know have directions for this one? Currently I am running the 2 ceramic heaters which are steady keeping the one side 90 right under the element, and its 80 on the other side of the cage. The Herpstat is just a expensive thermostat at this point. I would like to use the herpstat to run the heaters. Also has anyone heated these cages with just flexwatt? I reallly want to stack them.
