Toshiba RAS-10SAVP-E Operation flow and applicable data, etc Description, Heating operation

		Item				Operation flow and applicable data, etc.					Description
2. Indoor fan				<In heating operation>							1) When setting the fan speed to L,
	motor control										L+, M, M+ or H on the remote
											controller, the operation is per-
											formed with the constant speed
		HEAT ON
											shown in Fig. 3 and Table 1.
											2) When setting the fan speed to
		Fan speed setup									AUTO on the remote controller,
							MANUAL
											revolution of the fan motor is
										(Fig. 3)	controlled to the fan speed level
											shown in Fig. 5 according to the set
							Indication			Fan speed	temperature and room temperature.
							L			W8	3) Min air flow rate is controlled by
							L+			(L + M) / 2	temperature of the indoor heat
		AUTO									exchanger (Tc) as shown in Fig. 4.
							M			WA
											4) Cold draft prevention, the fan speed
							M+			(M + H) / 2
											is controlled by temperature of the
