Description
The new DT92 family of wireless digital room thermostats is a range of market leading products designed to provide comfort with economy in modern heating systems. Comprising a battery-powered room thermostat and a mains switching relay box, DT92 features robust 2-way RF communications between the units. This allows signal strength testing to help the installation process.The RF link between both units is already set (prebound) at the factory, so the product is ready for
immediate installation. Energy efficiency is addressed by state-of-the-art TPI control performance and an ECO button energy saving feature. Applications include control of gas or oil-fired boiler systems, underfloor heating, electric heating and zoning systems. With a modern fresh look that complements any style of décor, and a range of valued features for users and
installers alike, DT92 sets the standard for simple environmentally-friendly wireless room thermostats.
