Seem fine have needed to use much for either heat or cooling since installation. Contractor installed with a new heat pump. Contractor had difficulty with setting up wifi connectivity, but was able to set up once out of contractor mode myself. The jury is still out and may increase my rating later.
Easy to install. Works great. Fit in with my other Honeywell thermostats. Had to contact Honeywell technical Services through the online chat to make an option change in the programming but worked out and was very helpful.
This is my second unit as the first one stopped having a radio signal about weeks after installation. The unit does have apparent issue with wifi reception as even the replacement unit had some initial issues maintaining connectivity. Finally it seems to be working.
