There are three 'channels' of weather compensation. Their function is to supress a zone from going into demand, based on two temperature thresholds. Lets consider two scenarios:
- a warm morning
- a warm evening
Then in first case you have rising temperatures and in the second falling. So, for the morning case the user can define a temperature threshold for a rising condition, say 10 degrees: if the outside temperature is 10 degrees or above and rising then a zone using that weather compensation would not call for demand. Therefore on a morning that was getting warmer, zones would either not demand at all, or cease demand as temperature rises.
For the evening its the opposite way round, where zones can be held off until the outside temperature drops. We have different channels of weather compensation so you can apply them to different parts of the home.
