Can anyone suggest how I might go about figuring this thing out so I can lower the final temperature of the heater? It has one heat to melt the wax, and then another to maintain it. Pictures are here: http://imgur.com/a/BeN1v I flipped the back image horizontally so that the traces would line up with the components on the front in the pictures. The red dot in the top right is the same hole in both pictures. Here is the lm324n date sheet:http://www.componentschip.com/details/Texas-Instruments/LM324N.html Any advice you may have will be much appreciated. Note: I originally posted this in r/electronics before realizing you guys were here. Edit: In the interest of helping others decipher this in the future... Here's some info I'm using to come up to speed with these things:
looks like a system with phase-fired controller, pretty much the same like in dimmer-switches for lamps, where U can adjust the brightness. To reduce the heat the phase should be cut off earlier than in the actual state of the heater
