5. AUTO RESTART FUNCTION

MSH-07NV - E2 MSH-12NV - E2 MSH-18NV - E3

MSH-09NV - E2 MSH-24NV - E2

When the indoor unit is controlled with the remote controller, the operation mode, set temperature, and the fan speed are memorized by the indoor electronic control P.C.board. The “AUTO RESTART FUNCTION” sets to work the moment power has restored after power failure.Then, the unit will restart automatically. However if the unit is operated in “I FEELCON- TROL.” mode before power failure, the operation is not memorized. In “I FEELCONTROL.” mode, the operation is decided by the initial room temperature.

How to set “AUTO RESTART FUNCTION” 1Turn off the main power for the unit.

2Removed the electronic control P.C. board and the display P.C.board. (See page 60 and 62.)

3Cut the RESISTOR JR07 (MSH-07/09/12) or JR06(MSH-18/24) on the indoor electronic control P.C.board.

Operation

1If the main power (220/240V AC) has been cut, the operation settings remain.

2After the power is restored, the unit restarts automatically according to the memory.(However, it takes at least 3 minutes for the compressor to start running.)

Note:

The operation settings are memorized when 10 seconds have passed after the remote controller was operated.

If main power is cut while AUTO START/STOP timer is active ,the timer setting is cancelled when auto restart function works.

If the unit has been off with the remote controller before power failure, the auto restart function does not works as the power button of the remote controller is off.

To prevent breaker off due to the rush of startting current, systematize other home appliance not to turn on at the same time.

When more than one air conditioners are connected under the same power system,compressor starting current as large as that for all the compressors used flows at a time as soon as the units restart automatically.

Therefore, the specific counter-measures are required to prevent main voltage drop or the rush of starting current after power failure by providing the system to allow the units to start in regular succession.

MSH-07NV, MSH-09NV, MSH-24NV, MSH-12NV, MSH-18NV specifications

Mitsubishi Electronics has long been recognized for its innovative heating and cooling solutions, particularly in the HVAC industry. Among its notable offerings are the MSH-18NV, MSH-12NV, MSH-24NV, MSH-09NV, and MSH-07NV models, which showcase advanced features and technologies to enhance indoor climate comfort.

One of the standout characteristics of these models is their energy efficiency. Each unit is equipped with an inverter technology that optimizes power consumption by adjusting the compressor's speed according to the cooling or heating requirement. This not only leads to considerable energy savings but also reduces operational costs for users. The units have received high seasonal energy efficiency ratings, making them an environmentally friendly choice.

The MSH series incorporates advanced filtration systems designed to improve indoor air quality. These systems capture dust, pollen, and other allergens, ensuring that the air circulated in residential or commercial spaces remains clean and healthy. Some models feature a dual-layer filter that further enhances dust and odor removal, providing a more comfortable environment for occupants.

In terms of design, the MSH series is sleek and modern, allowing seamless integration into various interiors. The compact size of these units means they can fit into tighter spaces without compromising performance or aesthetics. Moreover, the whisper-quiet operation is another appealing feature, as it ensures minimal noise disruption during cooling or heating periods.

The control mechanisms of the MSH models are user-friendly and versatile. They come equipped with an intuitive remote control, allowing users to easily adjust temperature settings and modes from across the room. Additionally, some models offer smart connectivity features, enabling integration with smart home systems for added convenience and control via mobile devices.

Durability is another key aspect of Mitsubishi's MSH series. They are constructed with high-quality materials designed to withstand various environmental conditions, ensuring longevity and reliable performance. The outdoor units are particularly resilient, featuring weather-resistant components that allow them to operate effectively even in extreme temperatures.

In conclusion, Mitsubishi Electronics' MSH-18NV, MSH-12NV, MSH-24NV, MSH-09NV, and MSH-07NV models represent a blend of energy efficiency, advanced air filtration, user-friendly controls, and durable construction. These units reflect Mitsubishi's commitment to providing high-quality heating and cooling solutions that cater to a wide range of residential and commercial needs while ensuring comfort and convenience for users.
