Some important notes regarding standard Pool/Spa systems:
1. The OmniPL 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 “in-
terlock” feature (see CONFIGURATION for details) to ensure that the pumps operate only when
the filter pump is on.
6. The plumbing diagram above is intended to be used as a general guideline and is not a com-
plete plumbing schematic for the pool.
7. The air sensor must be installed if the freeze protection feature is enabled for the filter, valves,
chlorinator, other pool functions.
“Dual Equipment - Separate Heaters” for Pool/Spa Configuration
These systems have 2 complete sets of equipment (filter pump, filter, heater)—1 set for the pool and
the other set for the spa. Refer to the diagram below:
