Non‑Programmable Thermostat, 1 Heat / 1 Cool
The FocusPR N100 TH1110U4000 gives you simple, reliable temperature control for single‑stage furnaces, A/C units, or heat pumps without auxiliary heat. A big, easy‑to‑read screen, quick‑mount UWP® wall plate, and Resideo Pro App setup make life easier for both installers and homeowners.
System Compatibility
The FocusPRO N100 gives simple, dependable temperature control for single‑stage 24‑volt systems. It suits:
Conventional 1H/1C gas, oil, or electric furnaces with central A/C
Heat‑pump 1H/1C systems that do not use auxiliary heat
Dual‑fuel and wired‑outdoor‑sensor features apply only to the 3H/2C N100 models, not to the TH1110U4000.
Key Features & Benefits
Large Back‑Lit Display with Clear Font
Temperatures and settings are easy to see from far away and in the dark. Back‑light can stay on when the unit is hard‑wired.
UWP Universal Wall Plate
One screw pattern fits most Honeywell/Resideo models, so change‑outs are fast and tidy.
Set‑Point Range Down to 32 °F (0 °C)
Handy for garages or vacation homes that need a low “freeze‑protect” setting.
Filter‑Change Reminders
Programmable alerts help homeowners keep the system running efficiently.
Fan Lockout After Cooling Call
Optional setting lets the compressor shut off a few seconds before the blower to squeeze out extra coil cooling.
Battery or C‑Wire Power
Runs on two AA batteries when a common wire isn’t available. Uses hard‑wire power if it is.
