It allows you to set a radius so that when you are outside of that it drops/elevates the temperature to conserve energy

Does the thermostat making a clicking sound when it engages to turn on / off the furnace or airconditioner? My current Honeywell programmable thermostat is completely silent, which is desirable.

Battery Life

Our first set of batteries lasted about 2 months. The last 2 sets lasted about 2 weeks. When the batteries die the thermostat does not work at all and shows offline. This is at our camp and in the extreme cold we have no furnace at all and have to drive there to change the batteries. Does anyone else have this issue?
Asked by: Jaw
If you don't have a C wire, you must attach something like a FYVE 24Volt adapter plug in transformer, any internal battery (if this model truly has one as mentioned in the specs, the cheaper one uses AA, the more expensive one has no battery, but I think this is a typo on this one) or any rechargeable battery will not be charged. The cheaper NEST claims to not need a C wire but that is FALSE, because without one it will badly short cycle furnace on and off. And you can only use 24V adapter with more expensive Nests that have bot Rh and Rc connections. NOTE on some EMERSON Sensi you need to cut RhRc jumper to use C wire adapter

Can you schedule the fan separately? i.e. If the heating and cooling are set to off, the fan can be scheduled to run for 30 minutes every hour.
Asked by: daPieg
Just to follow up with this question, now YES, the updated app now allows you to run the fan for a % of an hour. So, if you set it to 50%, it would run the fan 30 mins every hour. This is a new option on the app, not on the thermostat itself from what I can tell.
