Installation Process
The installation of the TH4110U2005 thermostat involves several key steps, beginning with powering off the system. The UWP mounting system is used, followed by wiring the thermostat, and optional cover plate installation. Proper mounting is crucial.
Preparing for Installation⁚ Power Off and UWP Mounting
Before commencing the installation of your Honeywell TH4110U2005 thermostat, it is paramount to ensure your safety by turning off the power to your heating and cooling system at the breaker box or switch. This crucial step prevents any risk of electrical shock during the wiring process. Once the power is off, locate the Universal Wall Plate (UWP) included with your thermostat. Open the packaging carefully to access the UWP. Next, position the UWP on the wall where you intend to mount the thermostat, ensuring it is level. Use a pencil to mark the positions for the screw holes. Drill holes at the marked locations, and then gently tap the supplied wall anchors into the holes if necessary for a secure fit. The UWP is the foundation for your thermostat, so a proper, level mounting is essential for a successful installation.
Wiring Conventional Systems
When wiring the Honeywell TH4110U2005 for conventional heating and cooling systems, carefully follow the wiring diagram provided in the installation manual. The thermostat’s UWP has clearly labeled terminals for various wires. Typically, you’ll find terminals for R (power), W (heat), Y (cooling), and G (fan). Connect each corresponding wire from your existing system to the appropriate terminal on the UWP. Ensure each connection is secure and that no bare wire is exposed. If your system requires a common wire (C-wire), and you don’t have one, consider using a wire saver module like the THP9045A. This module, purchased separately, enables the use of a common wire using only four wires in a heat/cool system. Double-check all wiring against the manual’s diagram before proceeding. Incorrect wiring can lead to malfunctions or damage.
Optional Cover Plate Installation
The Honeywell TH4110U2005 thermostat offers an optional cover plate for situations where the existing wall has markings or holes that need to be concealed. This cover plate is installed after the UWP (Universal Wall Plate) is mounted. To install the cover plate, align it with the UWP on the wall. Ensure that the cover plate is level and fits securely over the UWP. Typically, the cover plate snaps into place or is secured with screws, depending on the specific model and its design. Refer to the installation manual for detailed instructions on how to attach the cover plate properly. This cover plate not only hides imperfections but also provides a clean, finished look to the installed thermostat. Make sure that the cover plate does not interfere with the thermostat’s operation.
Mounting the Thermostat
After the Universal Wall Plate (UWP) and optional cover plate are securely installed, the next step is to mount the Honeywell TH4110U2005 thermostat itself. Carefully align the thermostat with the UWP, ensuring that all pins and connectors are properly aligned. Gently press the thermostat onto the UWP until it clicks or snaps into place, indicating a secure fit. If screws are required, use the provided screws and tighten them carefully, avoiding over-tightening. Double-check that the thermostat is firmly attached and does not wobble. Once mounted, the thermostat should be level and flush against the wall. Before proceeding further, make sure the thermostat is properly attached to the wall. This ensures that the thermostat functions optimally and provides accurate temperature readings. The final mounting step completes the physical installation process.
Thermostat Settings and Operation
This section covers accessing the Installer Setup (ISU) for customized configurations. Understanding the thermostat’s deadband, which dictates when heating or cooling activates, is crucial for efficient operation and comfort settings.
Accessing the Installer Setup (ISU)
To access the Installer Setup (ISU) on your Honeywell TH4110U2005 thermostat, a specific button combination must be used. Begin by pressing and holding both the ‘Menu’ and the ‘up arrow’ buttons simultaneously for approximately five seconds. This action will initiate the advanced menu, granting access to the ISU. Once the advanced menu is displayed, navigate using the ‘Select’ button. This will allow you to step through the various options within the ISU. The installer setup menu allows for configuration of various system settings. These settings are essential for optimal performance and may include settings related to system type, fan operation, and other parameters. Refer to the installation guide for a detailed list of all configurable options within the ISU, as well as specific instructions for each setting. Proper configuration of the ISU ensures that your thermostat operates accurately with your heating and cooling system.
Understanding the Thermostat’s Deadband
The deadband in your Honeywell TH4110U2005 thermostat refers to a temperature range where neither heating nor cooling is activated. This feature prevents frequent cycling of your system, contributing to both energy savings and enhanced equipment lifespan. For instance, if your set temperature is 20°C and the deadband is 2°C, the heating system will only activate when the room temperature drops below 18°C. Conversely, the cooling system will only engage if the temperature rises above 22°C. The thermostat remains inactive within this 2°C range. This deadband is crucial for maintaining a consistent temperature without constant adjustments. Understanding the deadband will help you optimize your comfort and energy consumption, and can lead to more efficient system operation, as the thermostat allows the room temperature to fluctuate slightly before initiating a change in the HVAC system. Consult the thermostat’s manual for specific details on adjusting the deadband settings, if applicable.

Additional Information
The TH4110U2005 supports common wire usage and can utilize a wire saver module for systems lacking a C-wire. Optimal placement is in a frequently used room, away from direct sunlight and exterior walls, about 1.5 meters above the floor.
Common Wire Usage and Wire Saver Module
The Honeywell TH4110U2005 thermostat, while designed for straightforward installation, may encounter situations where a common wire, also known as a C-wire, is required for consistent power. In many older homes, or systems with only four wires running to the thermostat, a C-wire might be absent. This can lead to the thermostat drawing power from other components, potentially causing operational issues or inconsistent performance. To address this, Honeywell offers the THP9045A wire saver module, an optional accessory specifically designed for heat/cool systems needing a C-wire but lacking a fifth wire at the thermostat location. This module allows the sharing of an existing wire for both power and control signals, effectively adding a C-wire without the need to run new wiring. The THP9045A module is installed at the furnace or air handler and connected as described in its own instructions. By utilizing the wire saver module, users can ensure reliable power delivery to the TH4110U2005, maintaining optimal thermostat functionality and avoiding potential problems associated with inadequate power.
Best Location for Thermostat Placement
Selecting the right location for your Honeywell TH4110U2005 thermostat is crucial for ensuring accurate temperature readings and efficient operation of your heating and cooling system. The ideal spot is generally in a central living area, such as the living room or kitchen, where you spend a significant amount of time. Avoid placing the thermostat near heat sources like direct sunlight, lamps, or appliances, as these can cause inaccurate temperature readings. Similarly, do not install it on an exterior wall, as this may lead to temperature fluctuations and affect the thermostat’s ability to maintain a consistent environment. A height of about one and a half meters (approximately 5 feet) above the floor is recommended for optimal air circulation. It should be placed away from drafts, doorways, and windows to ensure the thermostat measures ambient room temperature. Proper placement of the thermostat contributes to better overall comfort and can also help you save on energy costs by optimizing heating and cooling cycles.
