4. Push the mode button to “OFF”.
5. Lastly, plug the prewired connector in the P7 position on the board.
IMPORTANT: The heater will display “OFF” when it is being remotely controlled by the
ECOMMAND 4. Some homeowners see the “OFF” display and, thinking this is a mistake,
change the mode to “POOL” or “SPA” which then disables the remote control by the
ECOMMAND 4. To prevent this: Remove the heater touch pad connector (P5) which will
disable the touchpad.

If “Pool Only” is selected, then the ECOMMAND 4 will switch the pool/spa valves to the
“pool only” position at the start of the programmed pool filtering time period or when the
super-chlorinate function is turned on. This may be desirable on some systems with in-floor
cleaners because it allows the cleaner to operate all the time the pool is being filtered and/or
the super chlorinate is running.
V1=Aux1, V2=Aux2
This menu appears only if the Pool/Spa Setup is “Pool Only” or “Spa Only”. When enabled,
Valve 1 (return) will follow the Aux1 output and Valve 2 (suction) will follow the Aux2 output.
When disabled (default), the return and suction pool/spa valves function normally.
Filter Off Valve Change
This menu appears only if Pool/Spa setup is set to “Pool and Spa - Std”. When enabled
(default), the filter pump will shut off for 35 seconds whenever the Pool/Spa valves are
turning. The pump will NOT shut off when a heater is in Heater Cooldown mode.

Filter Pump
For 2-speed pumps: When a 2-speed pump is configured, one of the AUX relays must also
be configured to control the low speed motor winding on the pump. Refer to the appropriate
sections in the Installation manual for specific information regarding the control logic for 2-
speed and variable speed pump operation.
For the Hayward Tristar variable speed pump: The Filter relay is used to supply input power
to the VSC pump control. The relay will be on when the filter pump output is on. When the
filter pump output is off, the relay will be off. On , off and speed is controlled by commands
sent to the pump.
Lowest Speed
This is the lowest speed that the variable speed pump is allowed to run at. It is used as the
lower limit in the Low Speed Settings Menu. Set lowest speed from 10% (default) to 50%.
