Honeywell TH4110U2005/U T4 Pro Programmable Thermostat

I replaced a very old (55 years) analog thermostat with this new system. I wanted a modern digital controller for forced air heating and cooling, programable, but without the need to connect to Wi-Fi, and compatible with older wiring that does not include a C wire (hence the need for batteries). Installation was straightforward. There are a host of settings that can be reviewed and changed, if need be, but the defaults work fine, or at least they did for me. There are YouTube videos to help, and the one detail question that I had about my specific wiring setup was answered with a quick phone call. It is understandable that the manufacturer would prefer a professional install, but they do everything they can to help the DIY homeowner if that is your preference. Recommended, works great.

Lo utilizo para climatizar un departamento en la playa, en un aire acondicionado de 5 toneladas !

Instalarlo es un costo no recuperable. Si no funciona.La garantía se pierde si no lo instala un técnico.Agradecería a Amazon. Instrucciones. Salio DE ONT, CA, al ver la información del embarque viajo por todo USA. en un débil sobre.

My plumber had given me the information for this brand but the non programmable version and I got this one, which is programmable for him with the same model numbers. He thought it was perfect and will update what he uses as a result. I have a 104 year old house with a gas furnace that runs a steam radiator heating system. This is all that’s needed and the programming is like the older version I had that wore out after 10ish years. Looks better, reads room temps properly and when winter comes should be fine. If not I will update, otherwise highly recommend for easy install over older version.
