Honeywell Home TH2110U4004 Programmable Thermostat 1H 1C

Product Description

The HONEYWELL HOME TH2110U4004 is a programmable thermostat designed for single-stage heating and cooling systems, including heat pump applications. It features a large display with clear font for easy reading and programming in residential and light commercial settings. The thermostat supports both hardwired and battery power methods and includes auto changeover between heating and cooling modes. Push-button controls keep operation straightforward for homeowners while simplifying setup for the installing technician. It operates across a temperature range of 32 degrees F to 120 degrees F and handles relative humidity from 5 to 90 percent, non-condensing. HVAC technicians install this unit as part of a standard low-voltage thermostat replacement or new system commissioning.

The TH2110U4004 suits residential and light commercial single-stage heat pump and conventional forced-air systems with 1 heat and 1 cool stage. It supports multiple programming schedules including 5-1-1 day, 5-2 day, 7 day, and non-programmable modes, giving installers flexibility to match the schedule to the occupant's needs. The UWP wall plate design is compatible with standard wall plate footprints, reducing patchwork and simplifying changeouts. The snap-on private label option makes this unit suitable for contractors who badge thermostats under their own service brand.

Verify that system voltage and wiring configuration are compatible before powering up. Follow the thermostat wiring diagram included with the unit and confirm changeover mode is set correctly for the system type before commissioning.
