I have one of those most new plus honestly current smart control units in my cabin for my central heating plus a/c unit unit.
I have had this smart control unit almost 6 months or so now.
And the other morning I observed a major issue with the smart control unit. The timer that you program for it go on plus off at a particular time was off by about 10 minutes. This was a problem plus not normal. I knew at this point I had to do one of 2 things. The first would be to just split my losses plus go out to buy a brand current smart control unit. The other would be to call the local heating plus a/c supplier to send out a certified heat plus a/c specialist to service the timer plus programmer of the smart control unit that goes with my central heating plus a/c unit unit. I decided to call the local heating plus a/c supplier first to see how much they would charge to come out plus try to service whatever was going on with my smart control unit. And after them quoting the price I had just offered up plus decided that it would be way cheaper to just go out to the store plus buy a brand current smart control unit plus then bring it cabin plus reinstall it myself. This would save me hundreds of dollars compared to what the local heating plus a/c supplier wanted to come out plus service my smart control unit’s programmer. It just was not worth it.
