I have a building with CSI controls. There are two Package Rooftop Units (20tons) that are continuously short cycling big time. The are controlled by a CSI MR88R micro regulator controller. Nothing is labeled and I have no idea what the unit is supposed to be controlling to.
Internet searches turn up very little since CSI was aquired by TAC. Does anyone have the software or manuals to these controllers. I would love to rip them out but the whole building is controlled by CSI controllers. The is a main board in the back of the building where the LAN communication lands on. (Model#7790).
Any help would be appreciated!
