Nest Temperature Sensor & Safety Temperature

[thedang42]

Hey team-

I want to use a Nest Temperature Sensor to activate my heat when the temperature of the sensor drops below 40 degrees F.

I want this because there is a closet that the heating zone includes with pipes that are prone to freezing.

I DO NOT want the zone to turn on heat based on my Temperature Sensor EXCEPT when it drops below the safety temperature.

Is this possible to set up or is this hopeless? Would it work if I set the entire zone to heat based on the temperature sensor?

Thank you in advance!

Hey thedang42,

Apologies for the late reply. I wanted to follow up and ensure you are good to go. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further. 

Best regards,

Hi Jake-

I am not good to go. As far as I understand, my request is not a feature that is available in Google nest. But this is not a feature that is easy to test and the manual doesn’t really say if it this would work.

I have the same question, does all nest temperature sensor trigger safety temperature if it drop below the setting or only the selected room will trigger the safety temperature?

Unless Nest has made an update or changed something since my original post (which is possible, I haven't checked..), the answer is NO. You cannot use the Nest temp sensor in this way. It only will trigger for the sensor it is set to detect. For what it's worth, I believe (but haven't verified) that the Honeywell smart thermostats can be used in this manner... I hope GOOGLE sees this and makes a worthy update to add this feature! Otherwise, consider the Honeywell

I also have the same question.  I'm installing heat pumps so my boiler will not be heating pipes in my house as often. I would like to know if the sensor can be used for freeze protection turning on my boiler if my sensor sees my safety temp settings.
