My Johnson A419abc-2c Temp Controller on my Portage&Main owb is no longer working correctly, it's been in use for 10 years now. Apparently this model is longer available. Is there a replacement available for the A419abc-2c? I see the model A421abc-02 is available, would this be the replacement for the older version?
Currently my boiler is shut down until i get a new temp controller.
