Description: Up for sale is a used but tested circuit board for all Dometic self-contained air conditioners, air handlers, Radomes and split systems built in the last 10 years or more. U-board works with the following 8-pin thermostat displays: Passport I/O, Cap Touch, Elite II and Smart Touch. It also works with QHT, SMXII & SMXIR 6-pin Cruisair displays. Board is green and measures 5.25" x 4.25". Buy with confidence as we are marine AC experts and will be sure you have bought the right board. Ask if any questions. We respond quickly. Most of our boards have been removed by our service crew from leaky AC units and tested. Limited stock. 30 day exchange warranty. Due to slight variations, image may not be the exact board you receive but it is guaranteed to work. Contact us for any questions. The board has 3 black jumpers. Remove the JP3 jumper if you are using a 10K remote temperature sensor and not a 3K. The difference between the two sensors is about 50 degrees. Remove the JP1 jumper if you are using this board on an air handler and it does not have a pump or compressor. Remove the JP2 jumper of your unit to activate a low pressure switch. Most AC units only have a high pressure switch. The high pressure switch must be connected for the board to function. No network capabilities. Red light indicates power. On the u-board are three telephone jacks. MA display is for Marine Air 8-pin displays while CA display is for Cruisair 6-pin displays. You can only have one display connected. The third jack is for an external temp sensor. If you have a 4-pin 3K temp sensor, leave the JP5 jumper in place. If you have a 6-pin 10K temp sensor, remove the JP5 jumper.
