Just built a Heatermeter 4.3. Everything seems to work well with the exception of the servo. It does not move smoothly when opening/closing. Instead, it seems to stutter. It will open/close to the desired percentage, it just does not do so smoothly. Additionally, if the Heatermeter while in manual mode, the servo will get a very short/small burst. It won't move, but I can hear it "tick". Any suggestions???
