We have re-designed our control box to include a protected circuit board to ensure it is moisture and vibration protected.  It is smaller in size than the standard control box previously provided and will have four mounting locations with rubber feet to prevent any disturbance while underway.  The display panel will work on a “phone cord” concept.  The Mermaid unit will still have the 4 foot “pig-tail” harness for ease of installation and remote mounting the electrical control box.  The standard thermostat cable length is 15 feet.  Longer is available upon request.

Older Mermaid units and other marine air conditioning products CANupgrade to this new model thermostat within minutes.  Removal of the prior electrical box, reversing valve coil (on Cool/Reverse Cycle Heat units) and thermostat will be the only required modifications!  Call for details at anytime.

The price below is for the new digital control panel to provided upon a newly purchased air conditioning unit.   For your convenience, all electrical connections inside the electrical control box have been completed.  Simply connect 110v or 220v power and the pump to the control box and you are all set!  As mentioned above, Conversion Kits are available to convert ANY self contained marine air conditioning unit.
