PERFORMANCE CURVES MSH-XV07UV - MSH-XV12UV - MUH-XV07UV - MUH-XV12UV - MSH-XV09UV - MUH-XV09UV - The standard data contained in these specifications apply only to the operation of the air conditioner under normal conditions, since operating conditions vary according to the areas where these units are installed. The following information has been pro- vided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.

MICROPROCESSOR CONTROL MSH-XV07UV - MSH-XV12UV - MUH-XV07UV - MUH-XV12UV - MSH-XV09UV - MUH-XV09UV - WIRELESS REMOTE CONTROLLER Once the operation mode are set, the same operation mode can be repeated by simply turning the OPERATE/STOP button ON. Indoor unit receives the signal with a beep tone.
(4) The initial set temperature is decided by the initial room temperature. Initial set temperature Mode Initial room temperature 26: or more COOL mode of "I FEEL CONTROL" Initial room temperature 25: to 26: minus 2: DRY mode of Initial room temperature 23: to 25: "I FEEL CONTROL"...
Time control When the three conditions as follows have been satisfied for 1 hour and 45 minutes, the compressor stops for 3 minutes. The indoor fan operates at the set speed. a. Compressor has been continuously operating. b. Indoor fan speed is Low or Med.. c.
Page 32
(2) Cold air prevention control 1 When the compressor is not operating, (1) if the temperature of indoor coil thermistor RT12 is 18°C or less, the fan stops. (2) if the temperature of indoor coil thermistor RT12 is more than 18°C, the fan operates at Very Low. 2 When the compressor is operating, (1) if the temperature of RT12 is 22°C or more, the fan operates at set speed.

3. Defrosting Defrosting of outdoor heat exchanger is controlled by DEICER P.C. board, with detection by the defrost thermistor RT61. (1) Starting conditions of defrost When all conditions of a) ~ c) are satisfied, the defrosting operation starts. a) The compressor cumulative operation time exceeds 40 minutes without the defrosting operation working. b) RT61 reads - 3.0°C or less.

8-5. FAN MOTOR CONTROL (1) Rotational frequency feedback control The indoor fan motor is equipped with a rotational frequency sensor, and outputs signal to the microprocessor to feedback the rotational frequency. Comparing the current rotational frequency with the target rotational frequency (High, Med., Low), the microprocessor controls SR141 and adjusts fan motor electric current to make the current rotational frequency close to the target rotational frequency.

(5) Dew prevention During COOL or DRY operation at Vane Angle 4 or 5 when the cumulative operation time of compressor exceeds 1 hour, the vane angle automatically changes to Angle 1 for dew prevention. (6) SWING MODE ( By selecting SWING mode with the VANE CONTROL button, the horizontal vane swings vertically. The remote controller displays “...

How to set the remote controller exclusively for particular indoor unit After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the remote controller for the indoor unit. The indoor unit will only accepts the signal from the remote controller that has been assigned to the indoor unit once they are set.
