I am using the circuit on this site http://wingzero.ath.cx/index.php?page=electronic-thermostat and I have 2 questions
1. The relay keeps switching on/off fast at the point when the preset temperature is reached until it stabilizes
2. I am using to control a heating coil (60W) which inserted inside an aluminum tube, is it ok to fix the sensor directly on the tube?
