FAQ
What are the main components of the Mitsubishi ductless indoor and outdoor units?
An air conditioner works by transferring the heat from the indoor air to the outside and transferring the coldness from the outdoor air to the inside.
Transferring the actual air would be highly inefficient, so air conditioners utilize a refrigerant along with components such as a compressor and expansion valve to get the maximum performance out of temperature differences between the inside and outside.
More information on how the refrigeration cycle works can be found at the following Wikipedia entries: Air conditioners and vapour-compression refrigeration cycle
What are the main functions of the Mitsubishi remote control buttons?
A heat pump is an air conditioner that simply reverses the flow of refrigerant between the outdoor and indoor units. Please note that all heat pumps are also air conditioners. When heating is called, the heat from the outdoor air is absorbed by the outdoor unit, then more heat is added by the compressor then pumped into the indoor unit.
After being ejected into the room, the colder refrigerant is pumped through an expansion valve causing the refrigerant to become very cold. That is why some heat pumps can still heat homes when it’s -25°C outside!
More information can be found at the Wikipedia heat pump entry.
What is Econo Cool operation on Mitsubishi ductless systems?
Econo Cool is an excellent energy saver for maintaining the desired indoor temperature once it has already been established. The indoor unit increases the desired temperature by 4°F (2.2°C) but constantly changes the indoor air flow speed. By adjusting the air flow speeds, one feels cooler than one would feel if the air flow speed was constant.
What is Powerful Mode operation on Mitsubishi ductless systems?
Powerful mode operation allows rapid cooling or heating to the desired indoor temperature. The internal setting temperatures will shift for 20 minutes to achieve the desired temperature quickly. After 15 minutes, powerful mode settings will revert to the previous settings. The indoor fan speed increases to “powerful-high” mode which is a faster speed than regular high mode.
When can the AUTO START/STOP timer be used?
The AUTO START/STOP timer is convenient for starting or stopping the unit whenever desired. Such as half hour before one comes home from work, before one goes to bed, etc. The AUTO START/STOP timer works only up to 24-hours in advance and the correct time must be set on the remote control in order to work correctly.
What if the main household power is turned off, such as during a black-out?
The operating mode, the set temperature and the fan speed are memorized by the indoor unit’s AUTO RESTART FUNCTION. The unit will restart immediately once power is restored to the unit. However if the AUTO START/STOP timer is active before the power failure, than the timer is cancelled once power is restored. If the unit is OFF before the power failure, than the unit will remain off once power is restored.
