2. Plumbing 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.

The ECOMMAND 4 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 (only when optional external chlorination is used). 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. 4
