Just added this ABB Temapture Contoller after testing for the last week to make sure it would function properly. Got it set for a 2 degree swing in tempature.
It is setup to turn on an outlet that I have mounted in the bottom of the base cabinet that I now have the two 200 watt heaters plugged into. I set the heaters to max out at 84 degrees in case the controller fails for some reason or another.
I currently have the setpoint at 80 degrees. The high alarm is at 84 and the low alarm is set at 76 degrees. When either of the alarms are reached the controller will pick up an audible alarm that I also put into the cabinet to let me know something is wrong. Just in case I am now sitting there watching it...LOL
Here are a couple of pics.
