Has the digital age created a replacement for the l8124a Honeywell Operating controller for a efm 520. Do folk use other controllers ?

My kaa-4 came from the factory with a Hydrolevel 3250 plus digital triple aquastat. Has worked perfectly since day one and is very easy to set and adjust. It can also act as a LWCO when using an electrowell
