My point which, I probably made poorly, is that the closed loop, ground source system setup properly should require less adjustment and maintenence that a comparable air source system.
Clearly any system can benifit from enhanced control and monitoring. No telling how many megawatts are wasted in this country because of dirty air filters or clogged evaporators on forced air systems. Variable speed blowers provide a means for a dehumidification cycle but few systems are being installed with the humidistat required to utilise this feature.
I could go on but the point being that there is nothing specific to the geothermal cycle that requires the consumer to be conversive in ladder logic to enjoy the benifits of these type systems. They are little different in their maintenence demands than the refrigerator purring away in the kitchen.
Multi-zoned, multi-staged or mixed systems are by their nature more complex be it geothermal, air source or a boiler system. The system designer and installing contractor are the keys.
