Quickly is there a way to drive a heater element without the PID? Just manual control petentiometer or something?
Look up "pulse width modulator" or "PWM".
You can build one for just a few dollars and it will let you dial the effective power up and down with the twist of a knob.
You still need an SSR (PWM controls the SSR).
