Our Expert's Opinion
"The T3 is the preferred choice for heating professionals!"Honeywell T3 Wired Programmable Thermostat T3H110A0066
Designed to perform across a wide range of applications (from social housing to new‑build developments and large‑scale installations) the T3 Series thermostats have become a trusted favourite among heating professionals. They’re quick to install, fully compatible with multiple boiler types and system configurations, and their intuitive programming makes them just as appealing to end users.
The T3 Series features a large, easy‑to‑read screen with clear icons, displaying temperature and date/time at a glance. It supports both 7 day and 5/2‑day scheduling and comes with a ready made programme to simplify setup. Users can choose up to four time periods per day and easily copy settings across the week, with the option of 12 hour or 24 hour clock formats. A backlit display enhances visibility, while built in memory ensures all programmes are retained indefinitely. The thermostat also includes restore schedule and factory‑reset functions for quick adjustments when needed.
Engineered for broad compatibility, the T3 works with 24–230V on/off and OpenTherm appliances, including gas boilers, combi boilers and heat pumps. Temperature readings can be offset to suit the thermostat’s mounting position, and adjustable minimum on time and cycle rate settings help ensure smooth operation with a wide variety of boilers. For installations in public or shared spaces, the thermostat can be locked to prevent tampering, and upper and lower temperature limits can be set to avoid extreme or unsafe adjustments.
