Looking at the on-line 360 view of your model it appears the remote display/control is on the cabinet directly across from the entry door, next to an electrical outlet. It should have a round button and 3 rectangular buttons with a LED display. It should look similar to what is on the inverter. This should be correct if the on-line info is correct.
