Daily and weekly chrono-thermostat for Heating / Cooling, equipped with the powerful ARM Cortex-M3 processor, a breakthrough in technology and 32-bit architecture, allowing block programming

Combines advanced technology, with an innovative memory accelerator, that generates high performance and low energy consumption

Advanced management of the processes of activation / deactivation of the boiler that provide a considerable greater savings and efficiency, up to 30% savings compared to other thermostats on the market

PASS security function that locks the keyboard, prevents tampering and access by unauthorized personnel

By means of the fuzzy-logic algorithm, it makes a prediction of the heating needs in the house, so that it anticipates according to the temperatures detected outside with respect to the existing ones inside. With this it manages to generate greater savings and comfort to the users of the house. It does not matter what type of heating is used, since the algorithm itself, together with the technology of this chronothermostat, learns so that it becomes more accurate with each cycle. The greatest savings are achieved in underfloor heating installations due to its high inertia, but it can be applied to any heating or air conditioning system

The fuzzy-logic system can be operated with or without an external probe, with an external probe it is much more precise
