Just look on ebay for a PID controller that has ramp function. Usually comes with 10-50 points for a program at different temperatures (ramping up and down) I have two in my heat controller for top and bottom. Only caution is that the Chinese instruction manuals are a pain to figure out.

Does rump function allows to program automatic increasing of temperature? I mean that my epoxy has such curing conditions: start at 60 degrees than each minute increase temperature on 3 degrees until it reaches 80 degrees.
