Mermaid M5 Cool Only Marine Air Conditioner – 5,200 BTU’s – 208/230V 

With a cooling capacity of 450 cubic feet, this unit is designed to cool up to a 26′ cruiser or a 28′ sailboat.

The Mermaid 5,200 BTU marine air conditioner has the smallest footprint on the market and only weighs 31.5 pounds. It is the ultimate in climate control. Don’t mistake that compact size for impaired function, however; the Mermaid unit packs the perfect punch of cool, comfortable air to keep your cabin temperate. Thanks to the expertise of Mermaid’s engineering and manufacturing team, even the electrical box on this unit only weighs 4.7 pounds.

The Mermaid 5,200 BTU marine air conditioner also has rotatable blowers and tapers into a V shape to make odd angle discharge installations a breeze. 4″ ducting and recommend a minimum of 2, 4″ round supply grills with this installation. This unit will run off of the new Honda EO1000i 1,000 watt portable generator while in cool mode. Another option Mermaid recommends is to use a Statpower pure sine wave 1,800 watt inverter and 450 amp hours of battery power and you can anchor out for the night.

Digital Control/Thermostat Options (Included w/Unit) – Select Programmable or Non-Programmable

Programmable Thermostat

Mermaid’s standard Digital Programmable Thermostat. Designed to be used with any Mermaid unit.

Programmable features allow for weekday and weekend setting for those boater’s who care to use the unit for dehumidification or simply climate control while not on board. The thermostat is also accompanied with 20 feet of four-wire thermostat cable and installation instructions.

Dimensions: 4 1/2″ length x 1 1/4″ width x 3 1/4″ height

Non-Programmable Thermostat

As an alternative to the standard Digital Programmable Thermostat, Mermaid offers a simple Non-Programmable Thermostat that can be mounted vertically or horizontally. It is ideal for applications where programming features will not be necessary.

Simply set the fan to AUTO (comes on with the unit) or ON (continuous duty), and set your desired temperature – and that’s it! The thermostat will now maintain that set temperature until you turn it off or change the temperature. Again, this item is ideal for folks looking for a simple controller and a slimmer wall mount design. This can be a FREE alternative to your Programmable Thermostat upon purchase of any Mermaid Air System.

Dimensions: 4 5/8″ length x 7/8″ width x 3 1/4″ height
