LENNOX 7500 ComfortSense LCD Programmable Thermostat 17G74 CS7500

Note: Photo 4, the display looks like it has some bubbles in it, because I put the original protective plastic that it came with back on the display, the display is perfect underneath. This was used from spring 2022 till January 2024. My wife paid $600 for this installed on the recommendation of the A/C tech. Bought it for the programmable features. We liked it! Now we had our compressor die on our 12 year old system. So we got a new system & a new controller came with it (practical the same just bigger.)
