Title: Not very efficient
Review: It's a decent thermostat if you like to maintain a constant temperature, but you cannot program a temperature swing. That means your air conditioner and furnace are cycling on and off very often to maintain a one degree zone.The biggest strain on the air conditioner is the compressor starting, and this also is less economical because it takes more power to start. Do you notice your lights dim a little when the air kicks on, well these Honeywells cause it to kick on and off way too much.Also if you have an electronic or glow plug type ignition for your Furnace it's the same thing. This all adds up to increased electric use and premature failure of some equipment.I would prefer to let the temperature of my home vary a couple of degrees then have all that on and off cycling. It seems like excessive and unneeded wear and tear on the components to meThis applies to all Honeywell thermostats according to the support request I submitted to them.
