Honeywell DT90E Eco Wired Digital Room Thermostat

The Honeywell DT90E Eco wired digital room thermostat has been designed to provide automatic temperature control of gas or oil fired boiler systems, underfloor heating, electric heating and zoning systems. It has an ECO button which gives timed setback or boosts temperatures to reduce energy consumption. This is a TPI (Time Proportional Integral) control programmer, which makes the boiler operate more efficiently and provides close accurate control. The OFF setting can be used for frost or hypothermia protection, assuming the system time control is also switched on. Its Installer Mode allows control to be matched to the system and user requirements, for minimum on or off times or set point controls.
