IMPORTANT SAFETY INSTRUCTIONS
When using this electrical equipment, basic safety precautions should always be followed, including the following:
•READ AND FOLLOW ALL INSTRUCTIONS
• |
! |
WARNING: Disconnect all AC power during installation. |
• |
! |
WARNING: Water in excess of 100 degrees Fahrenheit may be |
|
|
hazardous to your health. |
• |
! |
WARNING: To reduce the risk of injury, do not permit children to |
|
|
use this product unless they are closely supervised at all times. |
•A green colored terminal marked “Earth Ground” is located inside the wiring compartment. To reduce the risk of electric shock, this terminal must be connected to the grounding means provided in the electric supply service panel with a continuous copper wire equivalent in size to the circuit conductors supplying the equipment.
•A wire connector is provided on this unit to connect a minimum 8 AWG (8.4 mm2) solid copper conductor between this unit and any metal equipment, metal enclosures of electrical equipment, metal water pipe, or conduit within 5 feet (1.5m) of the unit, to connect the equipment assembly or spa to a circuit protected by a ground-fault circuit-interrupter.
•One bonding lug for US models (two for Canadian models) is provided on the external surface. To reduce the risk of electric shock, connect the local common bonding grid in the area of the swimming pool, spa, or hot tub to these terminals with an insulated or bare copper conductor not smaller than 8 AWG US / 6 AWG Canada.
•All field installed metal components such as rails, ladders, drains, or other similar hardware within 3 meters of the pool, spa or hot tub shall be bonded to the equipment grounding bus with copper conductors not smaller than 8AWG US / 6 AWG Canada.

1. Mounting the Equipment
ECOMMAND 4 Control Center
The ECOMMAND 4 is contained in a raintight enclosure that is suitable for outdoor mounting. The control must be mounted a minimum of 5 ft. (2 meters) horizontal distance from the pool/spa (or more, if local codes require). The Control Center is designed to mount vertically on a flat surface with the knockouts facing downward. Because the enclosure also acts as a heat sink (disperses heat from inside the box), it is important not to block the four sides of the control. Do not mount the ECOMMAND 4 inside a panel or tightly enclosed area.
When selecting a location, note that the standard cables supplied with the temperature sensors, and valve actuators (if applicable) are all 15 ft. (5m) long.
Temperature Sensors
Three sensors are included with the ECOMMAND 4. Awater sensor and an air sensor must be installed at all times for proper operation. Asolar sensor is required if the solar function is enabled.
Water Sensor
This sensor is used to measure the pool/spa temperature and is installed in the filtration plumbing after the filter but before either the solar or conventionally fueled heaters—refer to the plumbing overview diagram.
1.Drill a 3/8” (10mm) diameter hole in the PVC piping and remove all chips and burrs.
2.Insert sensor until O-ring collar sits flush on the hole.
3.Position hose clamp over the sensor and gently tighten until O-ring makes an adequate seal. Do not overtighten.
4.For maximum temperature accuracy, cover the sensor and 3” (6cm) of pipe on either side with insulation and white paint.
Air Sensor
Mount the air sensor outdoors. ! IMPORTANT: Mount the air sensor out of direct sunlight.
Solar Sensor
For solar applications, mount the sensor near the solar collector array so that it is exposed to the same sunlight as the collectors. Use additional cable (20AWG) if necessary.
Optional AQL2-SS-RF Remote Control (included with HPC-4-RC, HPC-4-
ACT-RC)
The ECOMMAND 4 is compatible withAQL2-SS-RF wireless remote control only. TheAQL2-SS-RF is a waterproof portable remote control that is designed to be used in and around the pool/spa area. The AQL2-SS-RF floats and can be left in the water for easy access. AsingleAQL2-BASE-RF Base Station must be installed on the ECOMMAND 4 in order to use this remote control. The maximum distance between the wireless remote and the base station on the ECOMMAND 4 main control unit is 400 feet (120m) line of sight or 200 feet (60m) through walls, etc. If in doubt about the distance, test operation before installing the remote.All wireless models require the user to run the “TeachWireless” routine in the Settings Menu. This information can be found in the ECOMMAND 4 Operation Manual.
2
Optional Base Station (included with HPC-4-RC, HPC-4-ACT-RC)
The AQL2-BASE-RF optional base station must be installed if theAQL2-SS-RF is used. To install the base station, remove the knockout on the upper left side of the ECOMMAND 4 main control unit, insert the base station, and then tighten the nut from the inside. Also refer to the Base Station manual and the diagram on page 13.
Optional Valve Actuators (included with HPC-4-ACT, HPC-4-ACT-RC)
For optional actuators used with the ECOMMAND 4—note that the internal cams in the actuator may also have to be adjusted depending on the way the actuator is mounted on the valve and the desired valve action.

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.

The ECOMMAND 4 Control Center requires both high and low voltage connections. Low voltage connections will be made to actuators, sensors, remote keypad, etc. High voltage connections will be made to pumps, lights, etc., as well as providing direct input power to the Control Center. Always:
-Ensure that Power is disconnected prior to doing any wiring -Follow all local and NEC (CEC if applicable) codes
-Use copper conductors only
Main Service (Power to the Circuit Breaker Subpanel)
The ECOMMAND 4 circuit breaker subpanel is rated for 100A service. Run properly rated conductors (L1, L2, N, and ground) from the primary house electrical panel to the main power connections on the ECOMMAND 4 circuit breaker base. The connection at the main house panel should be to a 240VAC circuit breaker rated at 100A maximum.
Grounding and Bonding
Connect a ground wire from the primary electrical panel to the ECOMMAND 4 ground bus bar. Also ground each piece of high voltage (120 or 240VAC) equipment that is connected to the ECOMMAND 4 control relays or circuit breakers. The ECOMMAND 4 should also be connected to the pool bonding system by an 8AWG (6AWG for Canada) wire. A lug for bonding (2 for Canada) is provided on the outside/bottom of the ECOMMAND 4 enclosure.
5
Circuit Breaker Installation and Wiring
Circuit breakers are to be supplied by the installer. Refer to the circuit breaker chart below for a list of suitable circuit breakers that can be used. Follow the code and the circuit breaker manufacturer’s rating requirements regarding the size and temperature rating for wiring. Note that some pool equipment may be required to be connected to ground fault circuit breakers—check local and NEC (CEC) codes.

General Purpose Outlet
If desired, a duplex receptacle with weatherproof cover (supplied by installer) may be installed in the knockouts on the lower right side of the ECOMMAND 4 enclosure. Per code, the receptacle should be a GFCI type. Alternatively, connect a standard receptacle to a GFCB.
ECOMMAND 4 Control Power
The ECOMMAND 4 requires 120VAC, 2A power to operate the control logic circuits. This power should be connected to a circuit breaker rated at 125% of the intended load or the next higher size available.
