I have gone around on this issue for three years since I installed a Gen 3 Nest. No one including Nest Pro or the support group can answer the question. The only solution I have seen is get an Ecobee. They allow the setting change. My system is radiant and forced hot air. Roughly 30 minutes after heat 1 starts, 2 comes on no matter what the variant is. Very annoying and I don't want to disconnect 2 for times when it's needed. Oh well....just something they can't do.
Hello Jake, it looked like from the nest documentation that Heat Stage 2 could be adjusted by a Nest Pro with the correct code. After chasing this down for years (that’s right!) nest says it can’t be done. The algorithm is too smart I guess. Too bad. I’ll give it fall of this year and then probably change out to Ecobee. They allow this function to be user altered. I just want heat 2 to come ONLY of the temp difference is greater than 4 degrees and ignore how long it’s on.
That the company tells us we cannot have control over stage 1 separate from stage 2 is unacceptable. I have a 2 stage system to save money and therefore energy. I could go on, but I will let this moment pass. I am sorry I bought this thermostat. It will go back into the box and removed from my wall. If the supplier takes it back, fine. If not, one quick hammer blow and into the wastebasket it will go.
