Honeywell Home T3C110AEU T3 Wired 7-Day Programmable Thermostat, White

Product Information

The T3 has been designed from top to bottom to satisfy the needs of installers; specifiers; property owners and end users. The installation sequence is intuitive and provides the installer with pre-programmed schedules; cycle rate option for different boiler types. All models have a maintenance alert. OFF position has an integral frost protection setting at minimum 5 C so that pipes in the house will never freeze Installers benefit from an installation process that pairs an easy to install receiver boxwith a thermostat that is easy to set up and hand over to the end user. This shortens installation time.

Optimum Stop saves energy by switching off a little bit earlier than the programmed time. If your home is up to temperature, you will not notice the effect on the temperature, but you should see a difference in your fuel bill.

Your Thermostat has optimization functions that aim to save energy while maintaining suitable comfort levels. The Thermostat displays during the optimization period if set. By default optimization is disabled, see instructions on the installation guide on how to activate it. Heat Demand: Room temperature is below setpoint – indicating there is a demand for heating (boiler activity might occur). The boiler cycles on and off as it controls the temperature, and sometimes the icon will be displayed when the boiler has cycled off. Installers benefit from an installation process that pairs a simple to install wall plate with a thermostat that is easy to set up and hand over to the end user. This shortens installation time.

Users can temporarily override the temperature set point and the current date and time are displayed on the screen Press and hold the Left & Right buttons for 5 seconds. The display will show the icon and (depending on the installer setting) the Thermostat will have limited or no keypad functionality.For specifiers, installers and users, the T3 series offers additional functionality that ensures that users of the controls can be restricted from using the controls incorrectly The Thermostat is powered by 2 x AA batteries, although a battery icon is not shown on the display during normal use. Wireless technology makes upgrading easier and the installation time shorter with less wiring involved. Repeat these steps to make adjustments to the remaining periods and days – or press to save changes and return to the home screen. will flash on the Thermostat when the wireless signal is lost – The Receiver Box LED will flash RED.

Save energy by switching the heating off when not required – e.g. during warmer summer months, or when doors and windows are open for extended periods of time. If the temperature drops to 5°C the heating will come on to prevent the heating pipes freezing. The thermostats in the T3 range are compatible with a wide range of boilers and systems including 24–230V on/off such as gas & oil boilers, combi-boilers and heat pumps.T3 thermostats cannot control electric heating. The T3 provides a whole host of energy efficiency measures. A full suite of Optimisation features (Optimum start, Stop and Delayed Start) plus adaptive ‘fuzzy logic’ protocols provide full control of the boiler. The T3 Series of programmable thermostats provide sophisticated automatic control of domestic heating systems. They have been developed to provide intuitive heating time and temperature control with a wealth of features that will make the T3 the first choice in a wide variety of installations, including social housing, new construction and mass installation situations. Delayed Start saves energy by slightly delaying the start of heating depending on the difference between the set temperature and the room temperature.

Your Thermostat comes with the following default schedule. Follow the next steps to adjust heating schedule. will flash when battery power has become critically low – you should change them immediately to make sure there is no disruption to your heating system.
