Some important notes regarding the control of Dual Equipment Pool/Spa with separate heaters:
1. When the system is configured for Dual Equipment:
a. The pool filter can be a one, two or variable speed pump.
b. The spa filter can be a one, two or variable speed pump.
2. The water sensor should be installed on the pool loop prior to the heater and will display the
pool temperature whenever the “Pool Filter” pump is running.
3. The dual equipment spa sensor should be installed on the spa loop prior to the heater and will
display the spa temperature whenever the “Spa Filter” pump is running.
4. The OmniPL can be programmed to accommodate spillover if desired. Note that spillover
operation will be automatically suspended whenever the spa filter pump is turned on.
5. The chlorinator cell must be installed in the pool plumbing. If spillover is enabled, then the
OmniPL can chlorinate both the pool and spa (during spillover operation). If not using spillover,
the OmniPL can control an AquaRite (purchased separately) for chlorination of both bodies of
water.
6. 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 “Pool Filter” pump is on.
7. The plumbing diagram above is intended to be used as a general guideline and is not a com-
plete plumbing schematic for the pool.
“Dual Equipment - Shared Heaters” for Pool/Spa Configuration
These systems have 2 complete sets of equipment (filter pump, filter) and shared heaters. Refer to
the diagram below:
Notes regarding the control of Dual Equipment Pool/Spa systems with shared heaters:
In the Pool/Spa Config., select:
1. When the system is configured for Dual Equipment:
a. The pool filter can be a one, two or variable speed pump.
