The Logic and Logic Code Combi ES ranges provide weather compensation
when fi tted with an outdoor sensor (which is available as an optional accessory).
Weather compensation works by measuring the temperature outside the home
and adjusting the temperature (or fl ow) of the radiators inside.
If the weather is particularly cold outside, the outdoor sensor will
communicate with the boiler intelligently to increase the radiator
temperature. This process also works in reverse, as the outdoor
temperature increases, the fl ow to the radiators too will decrease.
This process allows the system to operate more effi ciently by only
heating to the minimum temperature necessary and also preventing
spikes in heating activity.
