Plumbing Pool/Spa Configuration - Hayward Pro Logic PL-P-4-CUL Installation Manual

Pool/Spa system configuration
These systems use a single filter pump and filter. Pool or spa operation is controlled by two 3-way valves (suction and
return). Refer to the diagram below.

Some important notes regarding the Pro Logic control of Standard Pool/Spa systems:
In Pool/Spa Config., select:
1. The Pro Logic can be programmed to accommodate spa spillover, if desired.
2. A conventional heater (gas or heat pump) and solar can be used to heat both the pool and the spa.
3. If the chlorinator cell is plumbed prior to the pool/spa return valve, then both the pool and the spa can be
chlorinated
4. The water sensor should be installed prior to any heater or solar and will display either the pool or the spa
temperature, depending on the current operation of the pool. The temperature will only be displayed when the
filter pump is running.
5. If any water feature or pressure side cleaner boost pumps are used, be sure to enable the "interlock" feature
(see "Configuration Menu" for details) to ensure that the pumps operate only when the filter pump is on and the
system is in the "pool only" operating mode.
6. The plumbing diagram above is intended to be used as a general guideline and is not a complete plumbing
schematic for the pool.
7. The air sensor must be installed if the freeze protection feature is enabled for the filter, valves or aux outputs or
if the chlorinator is enabled.
