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 ECOMMAND 4 control of Standard Pool/Spa systems:
In Pool/Spa Config., select:
Pool/Spa Setup
Pool and Spa
1. 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.

Valve3 Pump Speed
This is the speed of the pump when the Valve3 output is on. The choices are the Settings
Menu speed and a speed that is unique to the Valve3 output only. The default selection is
“Settings Menu”. This is the speed of the pump that has been selected in the Settings Menu
for normal filter operation. If an alternate speed is desired when the Valve3 output is on, push
“+” or “-” and select from “Lowest” to “Highest” in 5% increments.
All Timeclocks
7-day
Move to previous/next configuration menu
Toggle between 7-day (default) and Weekend/Weekday time options
This selection affects ALL of the timeclock logic in the ECOMMAND 4. If “7-day” is
selected, each timeclock will have one set of turn-on/turn-off settings that operate every day
of the week. If “Weekend/Weekdays” option is selected then the user can enter one set of
turn-on/turn-off times for the weekend (fixed as Saturday/Sunday) and another set of turn-
on/turn-off times for weekdays (Monday through Friday).
