(1) Seasonal efciency calculation is detailed in package che - room units are available as option and includes: thermostat and room sensors, room unit controller wether
they are, or not, integrated in kits.
(2) For heat pump space heaters and heat pump combination heaters, the rated heat output P
rated
is equal to the design load for heating P
designh
, and the rated heat output
of the supplementary heater P
sup
is equal to the supplementary capacity for heating sup(Tj).
