Dual Equipment" Pool/Spa - Shared Heaters - Hayward Pro Logic® Installation Manual

5. The chlorinator cell must be installed in the pool plumbing. If spillover is enabled, then the Pro Logic can
chlorinate both the pool and spa (during spillover operation). Otherwise, the Pro Logic will only chlorinate
the pool and the spa sanitization will have to be handled manually.
6. 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 "Pool
Filter" pump is on and the system is in the "pool only" operating mode.
7. The plumbing diagram on page 9 is intended to be used as a general guideline and is not a complete
plumbing schematic for the pool.
8. When using the wireless spa-side remote control (AQL2-SS-RF), the "POOL" button will position the
valves for Pool mode and the "SPA" button will position the valves for Spillover mode.

Some important notes regarding the Pro Logic control of Dual Equipment Pool/Spa systems with shared heaters:
In the Pool/Spa Config., select:
1. When dual equipment is selected:
a. The "filter" pump automatically is renamed "Pool Filter" and can not be changed. The pool filter
can be a one, two or variable pump.
b. The "Aux1" output is automatically renamed "Spa Filter", its function is set to "Timeclock" and the
Interlock feature is forced to "Disabled". None of these can be changed. The spa filter can be a
one, two or variable pump.
c. The Valve3 configuration menu is disabled.
d. The heater(s) will be dedicated to the spa whenever the spa filter is on and the spa temperature
setting is not off.
2. The water sensor should be installed on the pool loop prior to the heater(s) 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(s) and will display
the spa temperature whenever the "Spa Filter" pump is running.
