    Samsung mini split

    I have a samsung mini split model AJ020JCJ2CH. It is all wired and installed and ran a test run. Everything ran for twelve minutes like it is suppose to. I realized I didn't get a remote control thermostat with it. I have my two F1 and F1 wires going to outdoor and indoor unit. Now when I turn everything on it times out in 2 minutes saying communication error. Which I understand because there is nothing telling it to turn on. Can I find 24 volts and hard wire a thermostat to the wall to run this unit or do I have to order a remote control for it. If you have to have that why in the world do they not include that in package. All my voltage is correct for outdoor unit and indoor unit. Thanks

    That model number looks to be an outdoor unit - what’s the indoor unit model number?

    AJ009JNNDCH/AA is the indoor unit. It sits on ceiling grid and blows air down.

    You need a remote, but you shouldn’t get a communication error. Something’s not installed right.

    What wire is used for communication?
    No, can’t wire in a 24V thermostat.
    You can install a wired wall controller or remote.
