Tmax problem with one room only

[lucky13]

All was fine last night but this morning my employee called me with this issue. Tmax 3A in the room displayed 91 and was buzzing. Manager Pro was not buzzing and that room displayed 2 dashes. I told her to cycle power to the 3A in the room and then do the same to the Manager Pro. 3A now displays zero but that room is still not picked up by the Manager. All other rooms are fine. What is most like at fault here, the 3A, the cables going from room to room, or something else? I know eventually everything needs to be checked but where should I logically begin to find the problem the quickest? The unit it is connected to is Sun Capsule Perfect 10. Thanks in advance for any suggestions.

Try setting the address to that room then recycle power to the manager. If it still does not recognize it then replace the comm chip.

Thanks Brian, I think that might do it. My employee discovered that she can set time on it manually so somehow it has lost the settings I have programmed in. Do you think that can happen when the power goes out? We did have a power outage during the night last night. Thanks again.
