This thing is awesome!!
Installed in my 40 foot camper. Installation was a breeze and this thing puts out some serious air! It’s extremely quiet, you can’t even hear it run. Very impressed especially for the price. Highly recommend!!

I loved my other Costway mini split so much that I bought a second one. The first one I use in my living room and the second one is in my dining room. They work amazing and the cost is better than any other brand I have looked at. Ian planning on buying more for my bedrooms.

Q:
what size of line is used with a 18000btu unit, I will need a 25ft line set, 3/8 5/8 1/2 ?
A:
For the 18000 BTU unit, the recommended copper pipe sizes are 1/4" and 1/2". Please ensure that these sizes are used. Additionally, extending the pipes will require the addition of extra refrigerant.

Still Confused?
Q:
Can you set a daily schedule and setpoints? If not can the unit be connected to a thermostat that can? Also is there a way to keep eco mode on or does it always leave eco mode after 8hrs?
A:
The unit features a 0-24 hour timer that allows you to set a daily schedule and customize the operation times. However, it cannot be connected to an external thermostat for separate temperature control. Regarding the ECO mode, it does not have a memory function to keep it activated continuously. The ECO mode will automatically exit after 8 hours of operation, requiring you to re-enable it if needed.

It operates by cycling the compressor on and off to maintain a desired humidity level while minimizing temperature changes.

A:
The temperature adjustment range for heating is between 16°C to 32°C (approximately 60°F to 90°F) .
