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 calorific load P
designh
,
and the rated heat output of the backup heater P
sup
is equal to the calorific output of the extra backup heating (Tj).
(3)
If Cdh is not
determined by measurement then the default degradation coefficient is Cdh=0.9.
