Notes:
H:High fan speed; M: Medium fan speed; L: Low fan speed.
1: . Cooling mode (2 and 4-pipe coil): entering air temperature 27°C DB/1 9°C WB, entering/leaving water temperature
7°C /12°C.
2: Heating mode（1）: (2-pipe coil): entering air temperature 20°C DB, entering/leaving water temperature 45/40°C.3: Heating mode（2）: (2-pipe coil): entering air temperature 20°C DB, enter water teperaure/water flow 50°C/*(same
water flow as in standard rating condition in cooling)
4: Sound pressure level is tested in a semi-anechoic test room.
5: The external static pressure test condition is 0 Pa.
