I recently hooked the Auber 1500 up to my new refrig. build. I'm using a 240/volt- 2700 watt broiler element as my heat source. The Auber controls a 120 volt contactor which tries to regulate the 240 volts. So far this is working out poorly. The pid seems to leak voltage so the contactor will not drop out and temp will soar. I then decided to put a small load before contactor,I used a small light. This did seem to eat up the small amount of excess voltage and contactor will now open and close. The problem I have now is the contactor opens and closes every one or two seconds. It is very annoying and I'm sure the life spand of contactor will be short. I don't know how to adjust parameters to make this better. I did talk to tech. at Auber and I couldn't understand his accent. The reason for the larger element is the smoker is quite large. Any help will surely be appreciated. I will post pictures soon of this last build.
