Just had a WB combi installed and went for their Wave controller, a feature of which is weather compensation.
Enabled weather compensation during the day yesterday when the temp setting was 14C. Actual inside temp was 19C, and outside was 11C.
I understand (well, perhaps that's over-stating it a bit) that it works by monitoring the water flow temp vs outside temp, but was a bit bemused that the combi's pump runs all the time, with the boiler firing so infrequently that it's basically circulating cold water.
Is that how it's supposed to work - will the pump run 24/7 with weather comp enabled? Seems a bit of a waste of 'leccy.
