For the life of me I can no longer get my single 4k to reverse since the last firmware update? I did a factory reset and still no joy. If I add a pump 2 (Non existent), connect it to the pump 2 connection, and have it run opposite of pump 1 the pump does run in reverse. So at least I know the pump does still run in reverse. I have tried flipping reverse on/of etc and still nothing. Any ideas or suggestions?
