Nest thermostat and "Safety Temperatures"

[hyankov]

So, Nest is marketed to have "Safety Temperatures" protective measures in place. I quote:

"Safety Temperatures can protect your home during extremely cold or hot weather. They can help ensure that your pipes won’t freeze or your home won’t overheat even if your thermostat is set to Off. Safety Temperatures are great to help prevent your home from going above or below certain temperatures by turning on heating or cooling when the set limits are reached."

I don't think this is exactly correct, or at least what "Off" means could be really misleading. I believe "Off" means the device is functional, but "turned off" (which is not turning it off really, it just makes it look turned off to the user). If the device is "off" due to the battery being drained, I don't think this functionality would kick-in, would it? Likewise, if the Nest thermostat fails (due to algorithm or whatever other bug) to ask the furnace to heat up, would the Safety Min Temperature still be honored, at least?

I guess I am trying to find out how reliable is this redundancy safety feature, because I think it has a very limited use case actually.

Hi hyankov,

Just one quick final check in here since activity has slowed down. We haven't heard from you in a while so we'll be locking this thread if there is no update after 24 hours. If you have any new questions, updates or just a discussion topic, feel free to start a new thread in the Community.
