Domestic boiler regulation without huge cabling and outlying sensors

After three changes of pipes or components configuration I finalize it. Main diference against mainly used config is P1 pump in paralel with boiler. It is best fot stable boiler temperature and more linear regulation characteristic of four way regulation valve. It is much more better than pumpe with thermostat (recomended by producer) or cammonly used pumpe on fourway valve low temperature intake to boiler.

A bit surprise was unsymetric system reaction for regulation attempt. Temperature up is quick but go down with output temperature take a time because hot water is mixing with relative hot radiators back water and result is small and slow change.
