Our Expert's Opinion
"The chosen brand by installers!"Honeywell DT4 Wired Room Thermostat On/Off DT40WT20
The DT4 Room Thermostats combine a slim, modern design with straightforward, user friendly functionality. They can be installed as standalone controls or integrated into a wider home comfort setup, including systems such as the HCC100 underfloor multi zone controller. Designed for versatility, the DT4 range works seamlessly with hybrid and low carbon energy solutions, including heat pumps, zoning systems and underfloor heating or cooling. They’re equally suitable for conventional and combi boilers, as well as newly installed heating systems.
The display uses an energy efficient LED that remains clear and easy to read, switching off when not in use to reduce power consumption. Built in boost and eco modes allow users to temporarily raise or lower the room temperature for a set period, helping to save energy and reduce running costs while maintaining comfort.
