KYROS Water Heaters

KYROS, advanced functionality

The KYROS second generation range includes advanced functionality. These new functions are accessible through the easy to use visual menu, with corresponding icons for each separate function.

A KYROS sanitary water heater, is your best option for safe efficient hot water, offering the same high Quality of all Rointe products and the Low Consumption due to the Fuzzy Logic Energy Control Technology.

Fuzzy Logic Energy Control

Low Consumption Technology allows optimising the water heater’s power consumption, making it possible to reach a non-consumption coefficient of 81% of nominal power.

Water heating progress function

Thanks to this function you will be able to see the increase in water temperature by percentage, until it reaches the temperature previously set on the control panel.

Anti-Legionaires’ disease protection

This function activates the water heater periodically, raising the temperature to 60ºC for one hour to to ensure that the bacteria causing this disease is never in the water.

Product functionality accessible via visual menus

These menus have been designed using identifiable icons for easy recognition, improving accessibility and facilitating access to all functions.

User Mode

This new function allows restricting the radiator’s temperature ranges, avoiding incorrect use that would increase consumption and thus increase your bill at the end of the month.

Infrared Communication

Easily programmable 24 hours, 7 days a week via the AIR Control remote or infrared BASIC Control.

Fuzzy Logic Energy Control –

the latest advance in energy savings technology

Fuzzy Logic Energy Control is the Low Consumption technology developed by the R&D department of Rointe and applied to the KYROS water heaters. The use of Fuzzy Logic Energy Control technology was tested by independent laboratories, and proven to save up to 81% in comparison to water heaters with no thermostat.
