Re: CHV-TSTAT force "extended" run times?

You may be on to something there...

I know I haven't changed the TStat setup since before I last updated the firmware, and I remember at the time thinking that the anticipators weren't having any/much affect. And the anticipators were set for what I "thought" would do what I wanted based on the manual (e.g. backwards from what reality appears to be) -- I'm using a "normal" single stage system (burner/forced air heat and ac). On the 2nd floor (Kitchen/Living) where the TStat is, there really isn't a "less bad" location for either the stat or an RTS, but I would like to get an RTS on the 3rd floor (Master Bed) anyway so I might force myself to do that while I'm doing some other work over the summer -- if any of this "free time" I hear speak of surfaces. I haven't seen the OD temp behave as you describe using an RSS for OD... Before that, I originally had a RTS that did all sorts of weird things toward the end of its life including at one point reporting the OD temp oscillating between something like +126F and -200F until you entered and exited setup, but that clearly wasn't a firmware issue.

I found the heat and cool anticipators did not work on the older firmware levels. But when I switched to v2.061, they started working. I seem to recall however that they worked in reverse of what the manual said. But I have a dual fuel system so that issue may only be unique to that mode. If the thermostat is in a bad location, you could use a remote temperature sensor. Even if you mount the sensor real close to the thermostat, you will probably observe an improvement. The big problem with the internal sensor is the inside of the TSTAT runs so hot that it messes up the internal temperature sensor. Depending on how the air current changes when the blower turns on, it can cause the thermostat to either short cycle or run too long. The internal sensor is mounted near the bottom of the thermostat. A downward draft will cause the internal sensor to heat up while an upward draft will cause the internal sensor to cool down. The big issue I have with v2.061 is occasionally the outdoor temperature sensor intermittently jumps up about 50 degrees and stays there until you reboot the thermostat or run the internal sensor calibration test. A different sensor behaves the same way and the problem started when I updated the firmware. Just downgrade firmware and waiting to see if the problem recurs.
