2. Time Delay [dEL]:
A. With the [dEL] (4 minute time delay) code message displayed use the [UP] or [DOWN]
arrow key to select either “1” to allow the time delay to remain active or “0” to deactivate the
time delay. Not pressing any buttons for 15 seconds will allow the controller to save the
selection and return to the normal operating mode. Pressing the {POOL/SPA] key will also
save the selection and step to the next menu parameter: [JAO] (External Controller
Interface).
B. CAUTION!!!: The time delay should only be deactivated for service convenience and must
be reactivated prior to placing the heat pump back is service. Failure to reset the time delay
feature could result in permanent damage to the heat pump compressor.

4. Water Sensor Calibration [tSC]:
If it is believed the displayed pool or spa water temperature does not match the actual
temperature, follow the steps below to verify and adjust the controller as necessary. Be certain
to use an accurate thermometer:
A. With the circulating pump in operation, and water moving through the heater, use a reliable
thermometer to measure the temperature of the pool or spa water. Be sure to measure the
water temperature away from returns. The object is to accurately determine the temperature
of the water entering the heater.
B. Once you have measured the water temperature, compare the result to the heater’s
displayed water temperature. If the water temperatures are the same or within 1 o F, no
calibration is necessary. If the temperatures differ by 2 to 3 o F, calibration is necessary.
Perform calibration procedure as follows:
3. Configuring for External Controllers [JAO] or [FS2]:
A. Configuring for External Controllers Using [JAO] Selection:
1) Follow the steps 1, A through 1, D to enter the service menu. Once [dEL] is displayed,
press the [POOL/SPA] key until the display shows [JAO].
2) With the [JAO] (External Controller Interface) code message displayed, use the [UP] or
[DOWN] arrow keys to select either “0” to disable the External Controller Interface, “2” to
connect a thermostat type controller (2-wire connection). Apply [FS2] configuration to
connect a thermostat selector type controller (3-wire connection); see “3. B,” below. Do
NOT use [JAO] “3.”
B. Configuring Remote Flow Switch / Automatic Thermostat Switching Using [FS2] Selection:
1) Follow the steps 1, A through 1, D to enter the service menu. Once [dEL] is displayed,
press the [POOL/SPA] key until the display shows [FS2].
2) With the [FS2] (Remote Flow Switch / Automatic Thermostat Switching) code message
displayed, use the [UP] or [DOWN] arrows to select either “0” to disable Remote Flow
Switch / Automatic Thermostat Switching, “1” to enable Remote Flow Switch / Automatic
Thermostat Switching.
