I share this, but as I am not back in TV yet, I do not have all of the facts. I will post what I find upon my return.
I had one installed this spring before leaving, I tested it before I left verifying the AC did not come on at 82, but did at 86 when humidity rose. This is my fourth summer I have left the same home unoccupied in TV. In the past three I set the thermostat to 82 degrees, no dehumidistat.
This summer I set the thermostat to 82 and the dehumidistat to 60%. The way it is installed the temp must be 82 AND the humidity must be above 60% for AC to come on.
I did not see any significant savings this summer. My home watch person verified the house was at 86 when they were there and the AC was off, so I am perplexed to say the least.
Either something not right, or the humidity has been high enough that it is almost always > 60% when the temp > 82.
