the pre-set temperature. When all the zones reach the pre-set temperature, the pump is disabled.

 Operation delay - funkcja pozwala użytkownikowi ustawić czas opóźnienia włączenia pompy po spadku temperatury

poniżej zadanej w którejkolwiek ze stref. Opóźnienie załączenia pompy stosowane jest po to aby siłownik zaworu

zdążył się otworzyć.
