Toshiba RAS-M10EKCVP-E, RAS-M13EKCVP-E Heating operation Heat pump model, Basic fan control

Item		Operation flow and applicable data, etc.							Description
2. Indoor fan	<In heating operation> (Heat pump model)								1) When setting the fan speed to
motor control									L, L+, M, M+ or H on the remote
									controller, the operation is
		HEAT ON
									performed with the constant
									speed shown in Fig. 3 and Table 1.
									2) When setting the fan speed to
	Fan speed setup				MANUAL				AUTO on the remote controller,
								(Fig. 3)	revolution of the fan motor is
									controlled to the fan speed level
									shown in Fig. 5 according to the
					Indication			Fan speed
									set temperature and room
					L			W8	temperature.
									3) Min air flow rate is controlled by
