(1) The calculation details are available on the package datasheet. The room unit refers to: sensors, thermostats and remote controllers included, or not included, in the kits.
(2) For heat pump space heaters and heat pump combination heaters, the rated heat output P
rated
is equal to the rated caloric load P
designh
, and the rated heat output of the
backup heater P
sup
is equal to the caloric output of the extra backup heating (Tj).
(3) If Cdh is not determined by measurement then the default degradation coefcient is Cdh=0.9.
