Product Information

DT90E Wired Digital Thermostat The DT90E 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. Energy efficiency is addressed by state of the art control performance qualifying it as a Load Compensator.

The DT90E has an ECO button energy saving feature which gives timed setback or boosts temperatures to reduce energy demand. This is a TPI (Time Proportional Integral) control product as defined in the Building Regulations, which make boilers operate more efficiently and provide close accurate control. The 'OFF' setting can be used for frost or hypothermia protection, assuming the system time control is also switched on.

'Installer Mode' allows control to be matched to the system and user requirements, adapting minimum on or off times, set point controls etc. Two wire, volt free connections are ideal for use with combination boilers or heating zones.
