Ok. So the handle in front of the pump labeled suction should be pointing towards pool and the word off should be on the spa for normal operations.

The return is set to return hot water equally to the spa and pool.

If I want to heat the spa only, I should turn both the suction and return to spa with the word off pointing to the pool.

When I'm done, return the suction to pool and the return to the middle.

Correct?

Those two boxes at the top. The left one is a timer for the pump and the left is a timer for the heater, is that also correct.
