Coefficient of performance threshold: If the coefficient of
S
performance of the heat pump is higher than the coefficient of
performance threshold, the heat pump takes priority. Otherwise
only the boiler back-up is enabled. The heat pump coefficient of
performance depends on the outdoor temperature and the heating
water set point temperature.
