Heagstat 5-1-1 Day Programmable Thermostat for Home, up to 2 Heat/ 2 Cool, DIY Install - C-Wire Not Required

Replaces this really old HVAC control panel with this one and it works perfectly. I wish the temp was in Celcius instead of of Fahrenheit but apart from that it works perfectly.

Not only is this good value for the money, but it is very capable since it supports two stage cooling and two stage heating. You can select between electric and gas heating and make other "technician" adjustments, but all the defaults worked for me. Installing the backplate was very easy for me since the mounting holes were identical to the Honeywell thermostat this one replaced. The unit comes in a nice little box with mounting hardware, and install and operating manuals and little stickers to apply to your wiring so that you know which wire goes to where. I didn't use the stickers (I took a good picture of the old wiring instead showing the B, R, C, etc. symbols), but it's a nice reminder to pay attention to which color wires go where since you have no idea how the wires were really wired down at the furnace, unless you look there too. I like that this unit has a hard button for cool/heat/off, much better than having to go into menus to change over. That little flip down lid at the bottom holds the two optional AAA batteries that saves settings during power outages. Nice that the batteries are easy to access.

Great and worked as expected

Performs it's function as anticipated

My old two heat stage Honeywell thermostat no longer always energized the heat, must have been a problem with the relay contacts. Looked for a replacement 2 stage thermostat and found this one. Although it is not the latest WI-FI enabled, it does what is needed. It is programmable for MON-FRi, and SAT and SUN. The nice thing is that there are adjustments for temperature calibration, cycle rate, and more. (The Honeywell was known for short cycling). There is no info in the book as to when the second stage heat is called on, but it seems like if you are more than a degree below the set-point the second stage is enabled, when the second stage is called for the number +1 appears above the heat symbol. Another nice thing is that it is powered from the heater but also has battery back-up, not like my old Honeywell that did not have battery backup, so with a loss of power I needed to reset the time. I did inquire to HEAGSTAT as to when the second stage was activated, as at one point it seemed like it was always calling for two stage heat. Their reply was disappointing, basically saying to hire an electrician. I would have liked an explanation of how the second stage is energized and info that when it was energized the +1 would appear. The manual also shows a +2, who knows what that is for as there is no info in the booklet. The thermostat so far seems like a great deal for the money, works well and has many adjustments, and is for two stage heat and cooling. I give it five stars, although the customer support was disappointing and a bit insulting.
