I have a customer who bought a used True GDM-35EM s#5313160 which is a coca cola merchandiser cooler. She didn't buy it from coca cola, she bought it from some guy, so it didnt come with a manual. It works fine, but she wants it colder. I looked at it, and it has an Elstat EMS55 Advanced digital thermostat controller.
I'm looking for information on the controller. It has a password, so I called true to ask about factory default settings- they said call coca cola. Coca cola won't give me any information on it, so I decided to come here..
Any coca cola techs or anyone who has a manual to this controller? I've searched online for a manual but can't find one. All I want to know is the factory default password to access the service menu.
