Correction..."IS there a set position that the Three position toggle switches should be set....". Thanks

We just moved into a new house, and our pool has an "attached" spa, which overflows into the pool when working properly. I am having trouble with the actuator settings working properly when the pool goes between the spa and pool modes. I there a set position that the three position toggle switches should be set on the back of each actator (I think there is one on intake valves and one on output valves). I have played around with them in different positions (up, middle and down), but I can't get it right. The spa either doesn't heat up or fully drains and it is driving me crazy!....any help would be much appreciated. Thanks.
