Compatible HVAC Systems
The Honeywell TH4110U2005 can be configured for a variety of single-stage HVAC applications, including:
- Gas forced-air furnaces
- High-efficiency gas furnaces
- Oil forced-air systems
- Electric forced-air systems
- Hot-water fan coil systems
- Air-to-air heat pumps
- Geothermal heat pumps
- 1 Heat / 1 Cool conventional systems
- 1 Heat / 1 Cool heat pump systems
Always verify system wiring and equipment requirements before replacing an existing thermostat.
Flexible Programmable Scheduling
The T4 Pro can be configured for:
- 7-day programming
- 5-2 programming
- 5-1-1 programming
- Non-programmable operation
The thermostat supports four daily schedule periods so heating and cooling temperatures can be adjusted around occupancy and daily routines.
Adaptive Intelligent Recovery
The T4 Pro uses Adaptive Intelligent Recovery to learn how long the HVAC system takes to reach the programmed temperature.
Instead of beginning heating or cooling at the scheduled time, the thermostat can start the system earlier so the desired temperature is reached by the scheduled time.
Honeywell UWP Mounting System
The TH4110U2005 uses Honeywell's UWP Universal Wall Plate mounting system, making installation and future thermostat replacement easier across compatible Honeywell Home T-Series controls.
Is the TH4110U2005 Discontinued?
Yes. Resideo currently lists the TH4110U2005/U as no longer available for purchase through Resideo.
Existing inventory may still be available from distributors.
What Replaces the TH4110U2005?
Resideo currently lists the following direct replacement options for TH4110U2005/U:
- TH2110U4004/U – FocusPRO P200 Programmable Thermostat
- TH2110WF4008/U – FocusPRO S200 Smart Thermostat
Always compare system stages, wiring, power requirements and thermostat features before replacing an existing control.
Is the TH4110U2005 Wi-Fi Compatible?
No. The TH4110U2005 is not a Wi-Fi thermostat.
It is a traditional programmable digital thermostat with local push-button controls.
Is the TH4110U2005 a 24V Thermostat?
Yes. The TH4110U2005 is designed for low-voltage HVAC systems and operates from 20–30 VAC, commonly referred to as 24V thermostat power.
What Is the Difference Between TH4110U2005 and TH4210U2002?
The TH4110U2005 supports up to 1 Heat / 1 Cool for conventional or heat-pump systems.
The TH4210U2002 supports up to 2 Heat / 1 Cool for heat-pump applications, while also supporting 1 Heat / 1 Cool conventional systems.
Make sure the thermostat has enough heating and cooling stages for your equipment before substituting one model for another.
