Tekmar RTU 54 Replacement

I have a Tekmar 371 Control System with 054 RTU's in each of the 5 zones. All RTU's are currently set low for summer (12oC). One zone is calling for heat even though room temperature is 20oC plus. I switched the RTU with another zone and that (new) zone immediately called for heat. I assume RTU is the problem. The RTU is Tekmar 054 which I believe is discontinued. Can you advise what a suitable replacement would be.

Many thanks in advance.

Dave

    They did discontinue them for awhile, and then brought them back. I am thinking they tripled the cost though. They are definitely prone to issues.
