3.3.4 Domestic hot water eco and preheat modes
• Preheat mode, the hot water heat exchanger is kept pre-heated to reduce the time taken to deliver hot water at the tap.
• Eco mode is an energy saving feature which disables the Preheat function. Eco is enabled by default, during the initial appliance
start up and Eco is displayed.
In the Preheat mode, if there has been no demand for hot water for 24 hours the appliance will save energy by suspending Preheat
until there is a demand for hot water. At this time Preheat mode is re-activated. It is advised to use a twin channel programmer to
time the Preheat function and switch it off when it is not needed.
