odd control

Al Letellier

A company I consult for has called me to check into an odd control they found today, and I need some information.
Do any of you guys recognize the following: SteamController ZG-57 ????? Only info I have to date. Will be going to site first of the week and would like to go in with any possible info. No manuf. info on unit. Controls or monitors outdoor temp, condensate temp, etc.
Any info would be greatly appreciated.

Control

Based on the model# it sounds like a Honeywell/Centra control. I didn't realize they made controls for STEAM boilers but I wouldn't be shocked.

There controls were usually black rectangle shaped plastic boxes with a clear plastic cover.


hope this helps

Thanks for the info. I thought that it might be a Honeywell from what little I knew about them. Saw one a long time ago. Will know for sure next week when I see it.
