View Full Version : Hussmann Protocols

Does anyone out there know where I can buy controllers and boards for Protocol rack systems. I've been on the phone with Hussmann for the past week and they cannot help me at all. I'm looking for the 818-0500 controller and the 818- 0505 control boards. Any leads would be appreciated.

Looks like these are rebadged Carel pCO2 controllers, perhaps Carel can help.
