Wireless Replacement T4R Programmable Thermostat

The Honeywell T4R replacement chronothermostat (ref. T4H700RF2055) is the perfect solution for those looking to improve temperature management in their heating systems. This wireless model is designed for installations already using the T4R range, providing efficient and programmable temperature control for gas boilers, combi boilers, and heat pumps. Only the thermostat is supplied, without support, receivers, or other accessories, making it the ideal replacement for existing systems.

Flexible programming tailored to your needs

The Honeywell T4R allows for customizable programming to fit your daily routines. It offers two programming options:

• 7 days: to have a different schedule for each day of the week.
• 5/2 days: to differentiate between weekdays and the weekend.

Additionally, this chronothermostat includes a factory pre-configured program, so you can start using it immediately if you don't want to set one up from scratch. For each day, you can adjust between four and six independent time periods, allowing you to control the temperature according to your comfort needs at different times of the day.

Compatibility and ease of installation

The T4R is compatible with 24-230V on/off devices, such as gas boilers, combi boilers, and heat pumps, making it versatile for various applications. Installation is quick and easy, thanks to a three-step process: wiring, powering on, and testing. The improved wall plate with more space for wiring further simplifies installation.

Advanced comfort and energy efficiency features

This chronothermostat is not only easy to use but also includes advanced features that maximize comfort and energy efficiency:

• Optimal stop, start, and delayed start functions: The thermostat learns how your home heats up and automatically adjusts the on and off times to maintain the desired temperature without wasting energy.

• Adjustable frost protection: This feature protects your heating system on the coldest days, maintaining a minimum temperature to prevent freezing damage.

• Absence mode: Ideal for when you're away for a few days, it allows you to set a lower maintenance temperature for the duration you choose.

• Temporary override: If you need to change the temperature temporarily, you can do so with the temporary override option, either until the next set point or for periods of 1 or 2 hours.

Intuitive display and controls

The T4R chronothermostat is designed to be easy to use for all family members. Its extra-large LCD screen clearly displays information such as the current temperature, active programs, and current time. It also features optional backlighting, making it easy to use in low-light conditions. The function buttons are simple and intuitive, allowing smooth navigation through the setup menus, accessible via a specific button.

Among the visual indicators, the heat demand icon is especially useful during start-up tests, as it easily shows when the system is operating.

Additional features for greater convenience

• Automatic summer/winter time change: The T4R automatically adjusts the clock according to the time of year, eliminating the need for manual changes and ensuring you always have the correct time set.
