The design constraints were composed by someone with no experience building such a room.  I was told the PLC would only have to monitor the room temperature and relative humidity - the air conditioners would use their internal sensors for temperature, and dehumidifying was assumed to be included.

I remember a saying I was told years ago:  Do you know the best thing about beating your head against a brick wall ?  It feels so good when you stop.  I stopped worrying about the parts of the project that I had no input on or control over.

GlennA, normally we are deploying multiple sensors at different places and average of the sensor values are accounted for decision making. Even most of such devices are equipped with more than one sensor for better accuracy. In such cases these types of failover can be minimized.

You can only hope the feedback to the manufacturer prompted their engineers to make changes, Glann. Not necessarily, though. Let's hope that the move toward social media in design will help the feedback loop reach the design function.

naperlou;  I was puzzled that the two heaters were not balanced, but I wouldn't have found that out if the overheat hadn't tripped.  I contacted the manufacturer several times (e-mail) during the process.  I don't know if it caused them to review their design.

Glenn, that was good work.  It seems that the dehumidfier was not tested properly after it was desiged.  Kind of reminds me of 1960s English sports cars.
