The T3R Thermostat communicates wirelessly to the Receiver Box which is wired to the boiler. If the Thermostat loses wireless communication or becomes faulty, the boiler can be switched on or off manually using the button on the Receiver Box. 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. 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.

Users can temporarily override the temperature set point and the current date and time are displayed on the screen 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. Replace with 2 new 1.5V LR6 AA Alkaline batteries only – which should last approximately 2 years depending on Thermostat usewill flash when battery power has become critically low – you should change them immediately to make sure there is no disruption to your heating system. Your Thermostat comes with the following default schedule. Follow the next steps to adjust heating schedule. 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 Start learns how long it takes your home to reach a set temperature and then turns the heating on a bit earlier to achieve that temperature at the programmed time. OFF position has an integral frost protection setting at minimum 5 C so that pipes in the house will never freeze

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. 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 T3 has been designed from top to bottom to satisfy the needs of installers; specifiers; property owners and end users. will flash on the Thermostat when the wireless signal is lost – The Receiver Box LED will flash RED.

Over 100 years experience 

Delayed Start saves energy by slightly delaying the start of heating depending on the difference between the set temperature and the room temperature. Press the +or- buttons to adjust the set temperature. This temperature is set until manually changed again. For users, the T3 is the ideal choice for homes that require high levels of automatic control that provide significant energy efficiency for a wide range of boilers and systems.
