Information About 3ie Thermostat For Tile & Stone Floors

The Warmup 3iE? is also the first programmable thermostat to come with Active Energy Management?, which can save you up to 10% on your energy bills by actively prompting you to test lower energy consumption levels.

The new 3iE? programmable thermostat strikes the perfect balance between functionality and aesthetics.

Proportional Adaptive Regulation

The 3IE analyses the past performances of each cycle and, based on results, it optimises the commands sent to the heating system. This regulation minimises temperature variations and maximises comfort.

Conventional Regulation with Anticipation

Simple regulation which sends On/Off commands to the heating system according to a pre-selected temperature variation. The thermostat control algorithm includes an anticipation function which reduces the discrepancy between the thermostat reading and the temperature at the centre of the room.
