I had a new Grandfos UPS3 pump fitted today, and am trying to set it up. I want it on 2nd setting, but having problems. The green light is on setting 1 and there is a yellow light on setting 2. If I press the arrow the green light stays on 1 and I then have yellow lights on settings 2 and 3. If I press the arrow again I just get a green light one 1. Press it again and I'm back to green light on 1 and yellow on 2. Anyone got any suggestions how I can get green light on 2
