    Today while waiting on the system check I scrolled through the sensor readout.
    Delta-T showed 5*
    Water temp showed 32*
    Outside air temp was 80* same for box temp.
    @reeferwrencher is the delta-t sensor on the way out?
    Unit is cooling fine down to 40* in 10min. Delta-t shows -22
     
    reeferwrencher Thanks this.

    The delta t is the difference between supply and return air which at -22 is very good.The water temp reading 32 in an 80 ambient air is strange though, what s it reading now after running for a while?

    Water temp was 176* after 10min.
    I didn’t know that delta-t was temp differential.
    I had a sensor go bad last summer inside the trailer. I forgot the name of it,but it was diagnosed by being a huge difference between it and the other sensors.

    Yeah they should read close when the unit has sat empty and not running for a while maybe a bit of variance.The water temp is normal at 176 when running,sounds like you,re good to go.
