These are really nice thermostats that not only help save money through things like an “auto away” mode, they also work with the Nest smoke alarms to do cool stuff like shut down the heating if CO or smoke are detected. Anyhow, we ran into a problem that not only had the heating engineer stumped for a while it also resulted in us the heating engineer and I jointly toasting a gen 3 Nest. Good job I still had the Gen 2 as a backup! The issue is that Nest thermostats as do all similar alternatives leach power from the HVAC control lines in order to charge their batteries. My new furnace was one of those.

Replacing an old thermostat

I noticed a problem right away with trying to maintain a comfortable temperature in the rig. It seemed like there were large swings in temperature between the furnace or the AC on and off cycles.

Most of the articles recommended using the Hunter brand Model B, as it was capable of controlling the cooling and heating, plus the fan function.

I was able to find one in a local hardware store.

Apr 22,  · I installed a Honeywell Prestige with a colour hi def display (with our new furnace), and it is a 24 volt DC thermostat, with an onboard rechargaeable non-replaceable battery back up (the circuit board contains its charger).

Hey all, I have a question that I hope some folks who know more than me could help with. I am looking to upgrade to a wifi capable thermostat for a 2nd home. The house is small, near the coast and has a 2ton WaterFurnace Envision series 5 geothermal cube. Since we usually only spend weekends there, and sometimes go long winter stretches without going at all, we usually set the Geothermal at 55 in winter and 76 in summer when we leave, and then bring the system to temperature 2 degrees at a time during the winter as to avoid the back up heat kicking in when we get back.

It would be great to be able to go onto the internet to turn on the AC or heat in advance of arriving, so we do not have to wait for the temperature to come up or down upon arrival. It’s especially bad in winter when it’s 55 and we have to bring it up to 69 2deg at a time. As noted in many of the threads on this site and others, the Nest 2.
