Honeywell T4 Wired Thermostat Wall Mount

The Honeywell T4 Programmable Thermostat (reference T4H110A1022) is a modern and efficient solution for temperature control in domestic and light commercial environments. Designed to provide automatic time and temperature control, this programmable thermostat allows precise adjustment of the indoor environment, optimising comfort and energy savings.

Main features:

• Flexible programming: The Honeywell T4 offers 7-day weekly programming or 5/2-day programming, allowing temperature control to be adapted to the user's lifestyle. This is ideal for both homes and small offices where heating or cooling schedules vary throughout the week. Additionally, it includes a pre-configured programme for quick and easy installation.

• Versatile compatibility: This thermostat is compatible with on/off systems of 24-230V, including gas boilers, combi boilers, and heat pumps. This wide compatibility makes it a suitable option for various applications, allowing efficient control of HVAC systems.

• Easy installation: The Honeywell T4 is designed for easy installation with a 3-step process: connect the wiring, power up and test the system, and configure the thermostat. Additionally, its improved wall plate offers extra space for easier wiring, reducing time and complications during the installation process.

Advanced functions:

• Optimised start and stop functions: The thermostat incorporates smart functions that learn how the room heats up, automatically adjusting the start and stop times of heating to maintain an optimal temperature and minimise energy consumption. Additionally, it features a delayed start that allows the user to adjust the heating times according to their needs.

• Frost protection: The frost protection mode ensures that the system activates automatically if the ambient temperature drops below a certain threshold, thus protecting pipes and preventing damage caused by extremely low temperatures.

• Absence mode: The thermostat includes an absence mode, which allows setting a specific temperature during days when the premises are unoccupied, contributing to energy savings without compromising comfort when returning home or to the office.

• Temporary programme override: If it is necessary to adjust the temperature outside the pre-configured schedule, the Honeywell T4 allows a temporary override of the programme for a period of 1 or 2 hours, returning to the normal schedule after that time.

Design and ease of use:

• Extra-large LCD screen: The thermostat features a large LCD screen that makes it easy to read key information, such as ambient temperature, scheduled times, and operating status. The backlight is optional and has an extended light period to facilitate visibility even in low light conditions.

• Heat demand indicator: The heat demand icon on the screen allows easy verification of whether the system is operating, which is especially useful during start-up tests or when you want to check if the system is activated.

• Automatic time change: The Honeywell T4 automatically adjusts the clock during summer and winter time changes, ensuring that the system is always correctly configured without the need for manual intervention.

• Memory function: In case of battery replacement, the thermostat does not lose its programming thanks to its memory function, ensuring system continuity without the need for reconfiguration.

Technical specifications:

• Power supply: Operates with 2 alkaline batteries (included), and features a low power indicator that alerts when battery replacement is needed.
• Operating modes: The thermostat allows operation in manual or automatic mode, offering flexibility for the user to switch between programmed control and manual adjustments as needed.
• System compatibility: Works with boilers and heating systems of 24-230 V, making it suitable for a wide range of domestic or light commercial installations.
