What if the device could detect the onset of equipment failures?
Possibly relay the information to your home PC; indicating if the
machine is healthy or not--and whether it's likely to fail in the
middle of winter given the conditions you have now?

With the correct programming and sensors all of that is possible!

Plus you could have a report of the actual BTU/hr output of the condenser.
Of course, the report would be relevant only if both coils and the blower
wheel blades were clean!

Indoor and outdoor blower CFM could be program monitored as well.
The hot gas discharge line temperature should be monitored and a high temp
bi-metal cut off switch installed.
Stretch, Paul, Jake, and others know the possibilities in these areas. -
