Without a big long explanation I was trying to get some info, but I see more info is required.
There is something wrong with our Mermaid
12000 btu HVAC unit on our sail boat. A 36' Islander Freeport.
If the unit tries to come back on before 6 min it blows a breaker. We are thinking too much pressure in the compressor. After 6 min it runs fine.
We have installed (my wife and I, after much research and a big learning curve) two EasyStart™ 364
's. With great success!!
We have two Mermaid units a 12000 btu and a 5200 btu.
So now we have a good understanding of the Mermaid wiring.
We have purchased a new electrical box for the 12000 btu unit but it did not change anything.
We have had a several HVAC technicians come and check the unit out and have said it runs great but they are not able to address the "start back up 6 min problem". We have contacted Mermaid support several times but they have no answer either.
This or a similar product would solve the 6 min start up problem.
Our EasyStart™ 364
's have a 5 min delay built in but sadly that is 1 min short.
Add another twist:
If we control the 12000 btu uit with the FX-1 Digital Comfort Control Thermostat
which controls the unit for the first two minutes the unit works fine. We manulate the temperature so the unit comes on and off within two min.
We have replaced the breaker.
Checked all connections.
So there you have it, at least what I can think of now.
We are in Puerto Vallarta, Mexico.
