Eurovent energy class
FCEER/FCCOP
Connection diameter
Eurovent conditions: Entering air temperature = 27°C db/19°C wb – entering/leaving water temperature = 7°C/12°C, high fan speed.
Eurovent conditions: Entering air temperature = 20°C, entering water temperature = 50°C, same water flow rate as in cooling mode.
Based on a hypothetical acoustic attenuation for the room and the air distribution system of -9 dB(A).
This unit complies with all applicable standards for EC marking (for further details see Declaration of Conformity). Except the unit size 42N_S65 which is not CE labeled due to fan
efficiency regulation 327/2011 but is fully compliant with Machinery (2006/42/EC) and Electromagnetic Compatibility (2004/108/EC) directives.
