PID autotuning can be started at a close setpoint for quick autotuning. The low voltage output of this model from a controller rated at 40 amps SSR is well above the 25 amp electric oven (both elements) and 220 volts well under power, but later stuck with a maximum starting current of 25 amps on heating and stopped not on also over 400d F. There was no short circuit and the controller works, it was 220 VAC and hang. Not so good in a dueling oven that can reach over 900 degrees Fahrenheit.
