The Intelligent Delayed Start is an energy saving
feature which automatically reduces the warm up
time for the heating system.
As the weather becomes milder, Intelligent Start will
delay the heating start times so that the fuel is not
wasted bringing the room up to temperature earlier
than necessary.
