If you are looking for a reliable and easy-to-use thermostat that can help you save energy and money, you might want to consider the Honeywell TH4110U2005/U T4 Pro Programmable Thermostat. This thermostat is designed to work with most low voltage systems, including gas, oil, electric, heat pump, and hydronic systems. It allows you to choose from four different programming options: 7-day, 5-2, 5-1-1, or non-programmable. You can also adjust the temperature settings manually or use the automatic changeover feature to switch between heating and cooling modes. In this review, we will take a closer look at the features, benefits, and drawbacks of the Honeywell TH4110U2005/U T4 Pro Programmable Thermostat.

Features of the Honeywell TH4110U2005/U T4 Pro Programmable Thermostat

  • Large backlit display: The thermostat has a 5.44 sq. in. display that shows the current and set temperatures, the time, the system and fan status, and the battery level. The display is backlit with a blue color that makes it easy to read in any lighting condition.
  • Flexible programming: The thermostat offers four programming options to suit your lifestyle and preferences. You can choose to program the thermostat for 7 days, 5-2 days (weekdays and weekends), 5-1-1 days (weekdays, Saturday, and Sunday), or non-programmable. You can also set up to four temperature periods per day, or use the temporary or permanent hold feature to override the programmed settings.
  • Easy installation and setup: The thermostat comes with a UWP mounting system that simplifies the installation process. You can use the existing wires from your old thermostat or follow the wiring instructions in the user manual. The thermostat also has a built-in level indicator to ensure accurate mounting. Once installed, you can use the setup wizard to configure the thermostat for your system type, heating and cooling stages, fan control, and other settings.
  • Compatible with most low voltage systems: The thermostat works with most 24-volt systems, including single-stage and multi-stage heating and cooling, heat pump with or without auxiliary heat, and hydronic (hot water or steam) heating. It also supports up to two heat and two cool stages for conventional systems, and up to three heat and two cool stages for heat pump systems. The thermostat has a terminal block that accepts up to 12 wires and can accommodate various wiring configurations.
  • System and fan switching: The thermostat has a system switch that lets you select the operating mode: heat, cool, off, or auto. The auto mode automatically switches between heating and cooling based on the indoor and outdoor temperatures. The thermostat also has a fan switch that lets you choose the fan mode: on, auto, or circ. The on mode runs the fan continuously, the auto mode runs the fan only when the system is on, and the circ mode runs the fan periodically to improve air circulation.
  • Programmable fan: The thermostat allows you to program the fan operation for each temperature period. You can set the fan to run on, auto, or circ for each period, or use the same fan setting for all periods. This feature gives you more control over the indoor air quality and comfort.
  • Automatic changeover: The thermostat has an automatic changeover feature that switches between heating and cooling modes to maintain the desired temperature range. You can set the minimum and maximum temperatures for the changeover, or use the default settings of 3°F above and below the set temperature. The thermostat also has a compressor protection feature that prevents short cycling and damage to the system.
  • Battery powered: The thermostat uses two AA batteries to power the display and the settings. The batteries can last up to one year, depending on the usage and the quality of the batteries. The thermostat also has a low battery indicator that flashes when the batteries need to be replaced. You can also use a common wire (C wire) to provide constant power to the thermostat, if available.

Benefits of the Honeywell TH4110U2005/U T4 Pro Programmable Thermostat

  • Energy and cost savings: The thermostat can help you save energy and money by allowing you to program the temperature settings according to your schedule and preferences. You can lower the temperature when you are away or asleep, and raise it when you are at home or awake. According to the U.S. Department of Energy, you can save up to 10% on your heating and cooling costs by adjusting the temperature by 7-10°F for 8 hours a day.
  • Comfort and convenience: The thermostat can provide you with comfort and convenience by maintaining the optimal temperature and humidity level for your home. You can also use the automatic changeover feature to avoid manually switching between heating and cooling modes. The thermostat also has a large and clear display that shows the relevant information at a glance. You can also use the temporary or permanent hold feature to override the programmed settings if needed.
  • Reliability and durability: The thermostat is made by Honeywell, a trusted brand in the HVAC industry. The thermostat is designed to work with most low voltage systems and has a terminal block that can accommodate various wiring configurations. The thermostat also has a compressor protection feature that prevents short cycling and damage to the system. The thermostat is backed by a 5-year limited warranty from the manufacturer.

Drawbacks of the Honeywell TH4110U2005/U T4 Pro Programmable Thermostat

  • No Wi-Fi capability: The thermostat does not have Wi-Fi capability, which means you cannot control it remotely from your smartphone, tablet, or computer. You also cannot integrate it with other smart devices or platforms, such as Amazon Alexa, Google Assistant, or Apple HomeKit. If you want a Wi-Fi enabled thermostat, you might want to consider the Honeywell Home T9 Smart Thermostat or the Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat.
  • No learning or geofencing features: The thermostat does not have learning or geofencing features, which means you have to program it manually or use the preset schedules. The thermostat does not learn your habits or preferences, nor does it adjust the temperature based on your location or presence. If you want a thermostat that can learn from your behavior and automatically adjust the temperature, you might want to consider the Google Nest Learning Thermostat or the ecobee SmartThermostat with Voice Control.
  • No humidity control: The thermostat does not have humidity control, which means you cannot set the desired humidity level for your home. The thermostat also does not display the indoor or outdoor humidity level on the screen. If you want a thermostat that can control and monitor the humidity level, you might want to consider the Honeywell Home TH8321WF1001 Wi-Fi VisionPRO 8000 Thermostat or the Emerson Sensi Touch Wi-Fi Smart Thermostat with Touchscreen Color Display.

Conclusion

The Honeywell TH4110U2005/U T4 Pro Programmable Thermostat is a simple and reliable thermostat that can work with most low voltage systems. It offers flexible programming options, easy installation and setup, system and fan switching, programmable fan, automatic changeover, and battery power.
