8. Fuzzy Logic Energy Control technology
Fuzzy Logic Energy Control is a technology developed by Rointe to improve the energy management
required to maintain a stable temperature, analyzing its variations with an accuracy of ±0.25 ºC and
sending micro electrons to the heating element that transfer the heat to the atmosphere in the most
efficient way. When the
icon on the display panel is replaced with the
icon, then the Fuzzy
Logic Energy Control technology has been activated and is working.
9. Guidance
•
When a hot tap is turned on there may be a short surge of water. This is quite normal with unvented
systems and does not mean there is a fault.
•
When you first fill a basin the water may sometimes appear milky. This is due to very tiny air
bubbles in the water which will clear very quickly.
•
If water is seen dripping through the tundish at any time switch off the electricity supply immediately
and call the installer or the Rointe Technical Service department on 0203 321 5929.
10. Servicing and maintenance
•
Servicing and maintenance must only be carried out by a competent unvented hot water product
installer or by Rointe authorised personnel, at least once per year.
•
Before any work whatsoever is carried out on the installation, it MUST first be isolated from the
mains electricity supply.
•
Only use spare parts authorised by Rointe. The use of other parts will invalidate the warranty.
