35 NOTE : Coil frost prevention during COOL mode of “I FEEL CONTROL” There are two types of controls in coil frost prevention. ① T emperature control <MSH-07/09/12> When the indoor coil thermistor RT12 reads 4°C or below for 5 minutes, the coil frost prevention mode starts.
36 — HEA T mode of “I FEEL CONTROL” — 1. Indoor fan speed control (1) Followings are the fan speed in AUTO. Set temperature minus room temperature: 2 degrees or more ·············.
37 NOTE 1 :When the outdoor fan is OFF in heating, defrosting of outdoor heat exchanger is not detected by the defrost thermis- tor RT61. NOTE 2 :When connected to MXZ-32NV - outdoor unit,the MSH-07/0.
38 NOTE1 ● When the indoor coil thermistor reads above 18°C, indoor fan operates at VLo for 30 seconds. ● When the indoor coil thermistor reads 18°C or less, the indoor fan stops. NOTE2: Refer to the Service Manual OB185 when MSH-07/09/12NV - , MSH-07/09/12/18NV - , and MSH-18NV - are connected with MXZ-32NV - as multi system units.
39 8-2. COOL ( ) OPERA TION (1) Press OPERA TE/ST OP button. OPERA TION INDICA TOR of the indoor unit turns on with a beep tone. (2) Select COOL mode. (3) Set the TEMPERA TURES button.
40 SLEEP 8-6. AUT O V ANE OPERA TION (1) V ane motor drive MSH-N series is equipped with a stepping motor for the vane. The rotating direction, speed, and angle of the motor are controlled by pulse signals (approx. 12V) transmitted from indoor microprocessor .
41 (3) Positioning The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle. The positioning is decided as follows. (a) When the OPERA TE/ST OP button is pressed. (POWER ON/OFF) (b) When the vane control is changed from AUTO to MANUAL.
42 8-8. TIMER OPERA TION 1. How to set the timer (1) Press OPERA TE/ST OP button to start the air conditioner . (2) Check that the current time is set correctly .
43 8-9. EMERGENCY -TEST OPERA TION When the remote controller is missing, has failed or the batteries run down, press the EMERGENCY OPERA TION switch on the front of the indoor unit. The unit will start and the OPERA TION INDICA TOR lamp will light. The first 30 minutes of operation will be the test run operation.
44 9 SER VICE FUNCTIONS 1. COMPULSOR Y DEFROSTING MODE FOR SERVICE By short circuit of the connector JP607 and R853 on the outdoor deicer P .C. board, defrosting mode can be accomplished regardless of the defrost interval restriction. See Page 56 and 59.
