Mr Cool DIY Mini Split System is made for easy installation for the DIYer in you. To install this single zone mini split system all you need is a few hours and some regular tools. Nothing special is required. With 18000 BTUs, this system will cool a space that is about 550 - 800 sq. ft. or in terms of actual dimensions, that is a room that measures about 20' x 25' up to about 29' x 28'. The MRCOOL 3rd Generation Enhanced DIY mini splits now includes the new SmartController WiFi control module that features an easier setup process, improved functionality, and works with Amazon Alexa and Google Assistant, as well as access for control anywhere you have a connection. It can be used with Android or Apple smart phones or tablets.

The MRCOOL Smart Controller offers many features:
  • Global Control - Control your MRCOOL air conditioner or heat pump via your smartphone from anywhere in the world
  • Weekly Scheduling - 7 day scheduling functionality helps you schedule your air comfort per your preferred settings and time
  • Filter Maintenance Reminder
  • Geo Fencing - Automatically turn your system on before you arrive and switch off automatically after you have left
  • Usage Statistics - Keep track of your usage to control your costs helping you save energy, and money!
  • Timeline of Actions - See who is using the AC and their settings
The whole system ships in two packages. The indoor unit ships with all the required hardware needed for installation including a wall template and mounting plate, wall sleeve (to send the piping and line set through your wall), a remote, SmartController and the line sets. The quick connect line is 25' and is fully charged with R410A refrigerant. Because they are charged and sealed prior to shipping, assuming they are installed correctly, there should be no air in the lines when you turn your unit on! DIY line sets and DIY Couplers are available to extend the 25' included line set to accommodate your installation needs. Line sets are available in 16 and 25 foot lengths with 1/4" x 1/2" connections. When adding additional length, you will also need the corresponding Coupler which includes the required communication wire. Couplers are available with 50 or 75 feet of wire to accommodate your new line length. You will need to disconnect the original 25' wire and replace with the new wire. 
 
The outdoor unit features variable speed DC inverter compressor technology to help cut your energy costs without losing any benefits. It operates in the cooling mode down to 5°F. This makes it an ideal solution for use in computer server rooms, greenhouse and other areas that need to be kept cool year round. It will also operate in the heating mode down to 5°F as well. Gold Fin finish will help your condenser resist corrosion for years. The system features auto restart in the event of a power failure. Once power is restored, you system will be up and running with no assistance from you! 
 
Other features include:
  • Low Ambient Cooling to 5°F - perfect for server rooms, greenhouses or other applications that require cooling year round.
  • Sleep Mode -  automatically adjusts the temperature to maximize comfort during night time sleep. When in COOL mode, the unit will increase the temperature by 2°F after 1 hour, and will increase an additional 2°F after another hour. When in HEAT mode, the unit will decrease the temperature by 2°F after 1 hour, and will decrease an additional 2°F after another hour. After 7 hours operating in SLEEP mode, the system will switch off automatically.
  • Auto Cool
  • Auto Restart
  • Louver Memory - horizontal louver will automatically move to the same position it was last set to.
  • Auto mode feature - In the Auto mode, the system can logically choose the mode of Cooling or Heating by sensing the difference between the actual ambient room temperature and the setting temperature on the remote control.
  • Leakage Detection - if your system detects low coolant, an alarm will sound to alert you and to help prevent damage to your system
  • Gold Fin Condenser - Protection to resist long term corrosion
  • LED Controls
  • Variable 4 Speed Control
  • Fan Only Option
  • Follow Me Feature - by pressing the 'follow me' button and keeping the remote close to you, you tell the air conditioner to set the temperature from wherever the remote happens to be, this counteracts the tendency for the air conditioner to stop cooling or heating because the air around the unit has reached its set temperature
  • Dehumidifying operation - In DRY mode, the system will reduce the humidity of the air in the room for increased comfort. The system will automatically cycle between cooling and fan only modes to dehumidify the air.
  • Temperature Range - the temperature can be set within a range of 62F - 86F in 1°F increments

This system uses 230 Volts and has average Cooling Operating Costs around $119/year and average heating operating costs about $381/year (as provided by AHRI).
