Electromagnetic environment - guidance
RF emissions
according CISPR 11
Group 1
The Ultimate Comfort uses RF energy only for its internal function. Therefor, its
RF emissions are very low and are not likely to cause any interference in
nearby electronic equipment.
RF emissions
according CISPR 11
Class B
The Ultimate Comfort system is suitable for use in all establishments, inclu-
ding domestic establishments and those directly connected to the public low-
voltage power supply network that supplies buildings used for domestic
purposes.
Harmonic emissions
according IEC 61000-3-2
Class A
Voltage fluctuations/flicker emissions
according IEC 61000-3-3
