Jostudly, I need to press the temperature up and down buttons twice to get the read out on the remote to react to the change. However, after the first press, it responds to each subsequent increase or decrease with one press of the buttons. The key is to hear the beep on the unit, telling you the change has been received from the remote by the system.
My units, one identical to yours and one different, each delay before a change in settings too. The system needs time to react to the signaled changes. As long as your unit reacts to the change in settings within a few minutes, I think it is behaving normally -- like mine do, anyway. For example, on the very coldest winter nights -- -15C -- the unit sometimes goes into defrost mode in responding to an increase in temperature command from the remote. After a couple of minutes the heat is back, and the temperature rises as I have commanded.
Hope that helps. I think an analogy might be steering a boat rather than driving a car. The car steering response is obvious and immediate but the boat needs patience from the handler.
