Hi all, I am trying to come up with some sort of "change over" unit for a Comms room.
I have two seperate wall mount mitsubishi split systems both serving the same small area. There is only a need to run 1 unit at one time to cool the area, the second just there for back up (critical Comms equipment). Idealy I want to alternate them on a weekly basis, and have the second come in when the temp rises above the set point in high temperatures or if the current unit goes into fault.
I am aware the par 31 is capable of managing this, but these units are 8 years old and the software is not compatable.
I think mitsu supply a stand alone panel that will do all this and more, but it's very expensive. So I'm hoping there is an alternate solution.
