The T3 programmable thermostat

Developed to provide intuitive heating time and temperature control, featuring a wealth of functionalities designed to make it the preferred choice for a diverse range of installations.

Designed for compatibility.

T3 programmable thermostats are designed to work with on/off and OpenTherm® compatible heating and cooling appliances, such as boilers, heat pumps and district heating systems. Featuring both wired and wireless versions, they're designed to suit a variety of homes, and for a multitude of system applications.

Cost effective simple installation

The T3 series aims to make your everyday life easier. Fast commissioning saves a lot of time and energy, especially in mass installations. The wireless version comes with an easy-to-install, easy-to-commission boiler control module. For the wired version, simply install the wall-mounting frame, connect the wires, and it's ready to go.

Programmable, adjustable, customisable

Resideo understands that life is unpredictable. So opt for a pre-set 7-day program and easily change the temperature setting when plans change. You can easily select the pre-programmed 7 day and 5/2 day scheduling with up to 4 time schedules.

Compatible with heat pumps

Added parameters now means the T3 programmable thermostat works with heat pumps - giving your customers an easy to use, reliable option for their low carbon system.
