Warmup’s 3iE is a fully interactive thermostat with touch technology and energy monitoring for radiant heating that learns from the user’s programming changes and temperature selections. It allows users to view graphs of their recorded energy consumption against costs. The 3iE is user-friendly with an intuitive menu, simple words, can be set in several languages and comes in eight colors — black, silver, white, cream, blue, green, purple and pink.

 The thermostat can be used as a floor-temperature sensor, an air-temperature sensor or both. It automatically adjusts to changing external conditions to give optimal start-up times so there is no wasted energy. The Active Energy Management feature prompts users to choose the best and most efficient temperature in each room to save up to 10% on energy bills.
