The cassette works with the MrCool® DIY® Quick Connect® line set and the No-Vac® Coupler to increase the length of the line set. Not only does the unit offer quiet operation and multiple operating modes, but it also features the Elevation function that lowers the filter panel for easy air filter maintenance. Purchases of the MrCool® DIY® Series Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

Plus, you can quickly check the temperature of each room in your home from the easy-to-read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The five MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

The MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 Five-Zone Ductless Mini Split Air Conditioner System - 9K + 9K + 12K + 12K + 12K comes with many options, so you can customize your system based on your needs. Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Easily maintain your MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 Five-Zone Ductless Mini Split Air Conditioner Unit with alerts and reminders. Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes. Air filter cleaning alerts are automatic, and you can easily keep the minimal indoor units clean with a dry or damp cloth.

Will 500 5 stars defeat a mistaken rating?
Format: Hardcover
The future of the planet depends on this book and it received one star as a "mistaken novel!!" DO NOT look only at the stars, this seminal, recent, scholarly text, at an amazing price for the content (cf Springer for $300 US), outlines the disasterous imminent global economic and even nuclear consequenses brewing NOW in the Strait. I'm completing my third doctorate on simulating Strait diplomacy and military models, and Adam Liff's recent Cambridge article (open access) is a great preview of this amazing and crucial text-- Bayesian math plus Baha'i consultation are urgently needed to mitigate THE global trigger and planetary flashpoint which is about to destroy the global economy, or... worse.

Illuminating perspective on the evolution of thought of the political leadership in Iran
Iran's Grand Strategy is a well timed overview of the why's of Iran's leadership political outlook and the historical path that has taken them to where they are today. The book was written before this war has erupted between Israel/US and Iran and so discusses the political economy under the leadership of Khomeini and Khamenei, but it gives enough substance to allow the reader to translate this historical perspective into an understanding of the internal dynamics of Iran in this moment, something that is probably largely absent from the political calculus of the US when it made its decision to join Israel's strike The book is a work of political science and the history that has defined it. As such it starts with the Iranian revolution, the background to it, the politics of that day (which was mixing both socialist a-religious political groups with a religious political agenda for which the latter seized power) and how the leadership never really had a popular mandate to rule the country but consolidated power after broad discontent. Iran was subsequently really shaped by its war with Iraq and in many ways was a war of attrition and opportunism to varying degrees through time. Nonetheless this war shaped the leaderships views of how to govern and how to frame their mandate which was as the saviour of the country which would have to sacrifice to endure. Iran was the subject of chemical warfare, for which there were no sanctions. The US was seen to have subsidized Saddam's war initiative which provided ideological substance for considering the US as an enemy. The relationship with Israel is also discussed and how Iran took up the mantle of support for Palestinians as the much of other parts of the Middle East focused on a more narrow self interest. This period was define by the author's term Sacred Defence, where existential survival was the message for enlisting. This is also highlighted as how the regime became more defined by its security needs as determined by the IRGC rather than by the clerics. This phase shift has stuck and the author views much of the religious rationalization of political strategy as founded in security calculations from leadership of the IRGC along with the Ayatollah. This is why much major business is controlled by the IRGC and the Khamenei's son was projected to become the next leader despite hereditary rule as being anathema to an Islamic republic. The author discusses how Iran repurposed itself as an axis of resistance to US hegemony that was founded in its wartime survival mentality. That this largely has not carried over to its population despite it being fundamentally entrenched in much of the IRGC. The various democratic initiatives pursued often backfired as the leadership was voted against in parliamentary elections, though the real influence on politics was minimal given the Ayatolla's dominance. This transition of interest of the population and obstinance of the leadership led to increasing civil unrest and a pick up in protesting in the aftermath of the regional overthrows that took place in Egypt, Libya etc.. These episodes also further highlighted how the nuclear program remained a core asset for preventing external influence given Libya's voluntary decision to cease its nuclear program did Ghaddafi no favors at the time of being overthrown. These highlight the self preservation of Iran's leadship as being independent of the will of the people which is why there is fundamental disillusionment in the country of the future based on the existing political economy. The author spends time on the concept of Forward Defense, a guerilla warfare type mentality of the leadership to fill the power vacuum that emerged with the fall of Saddam. This had other regional reverberations in increased skirmishes with Israel through proxies and some religions fighting in Sunni/Shiite with Saudi and the Houthis as an example. Thus in the pursuit of resistance Iran ignored the externalities to regional players which have forced more isolation on Iran which is stuck in the past in its mindset and increasingly alone. This Forward Defense is part of the reason why settling on nuclear deals and having any mutual grounds for trust with the US has been impossible, with both sides having legitimate reasons for complete absence of trust. As such where we are today though not inevitable was never impossible. Overall this book was written for context of Iran's political calculus with no prediction for the current conflict but it is useful for that goal. I feel more informed for reading it and have a better perspective on why the views are as they are. It is also hard to deny there has been significant pettiness mixed with deep conflicting strategic interests that have led to the frictions on display in the last 20 years. Core interests will be difficult to reconcile, but the pettiness adding further barriers is getting more absurd by the day. Nonetheless if one wants to get some healthy perspective this is a solid book.
