Mermaid Manufacturing Flush Mount Controller – FX-1 Digital Comfort Control
he Mermaid Manufacturing FX-1 Flush Mount Controller includes a protected circuit board to ensure protection against moisture and vibrations. Improved fan speed control – variable speed control. It is smaller than the control box and has four mounting locations with rubber feet to prevent any discomfort while on the go.
The display panel works on a “phone cord” concept. The Mermaid units still have the 4 foot “pig-tail” harness for ease of installation and remote mounting of the electrical control box. The standard thermostat cable length is 15 feet. Longer is available upon request.

Have an older unit? No problem! Older Mermaid units and other marine air conditioning products CAN upgrade to this new model thermostat within minutes. Removal of the prior electrical box, reversing valve coil (on Cool/Reverse Cycle Heat units) and thermostat are the only required modifications – and Mermaid can help walk you through it.
