Switch, and All Double-Function Air Switch Controllers.

(Also see Appendix Item “B”)

3.3 Remote Flow Switch / Automatic Thermostat Switching [FS2]:

(Also see Appendix Item “C”)

A. Follow the steps 1a. through 1d. above to enter the service menu. Once [dEL] is

displayed, press the Pool / Spa key twice to display [FS2].

B. With the [FS2] (Remote Flow Switch / Automatic Thermostat Switching ) code

message displayed, use the Up

⇑ or Down ⇓ arrow key to select either (0) to

disable Remote Flow Switch / Automatic Thermostat Switching, or (1) enable
Remote Flow Switch / Automatic Thermostat Switching.

C. Refer to the additional instruction, entitled: Installing A Remote Flow Switch For

Automatic Thermostat Switching.

4. Water Sensor calibration [tSC]…

If it is believed the displayed temperature does not match the actual water temperature in the
pool or spa, follow the steps below to verify and adjust the control if necessary. Be certain to
use a reliable thermometer for maximum accuracy:

A. With 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 temperatures are the same or within 1

° F, no

calibration is necessary. If the temperatures differ 2 to 3

° F, calibration is necessary…

Follow the instructions below.

C. Follow the steps “1A.” through “1D.” above to enter the service menu. Once [dEL] is

displayed, press the Pool / Spa key three times to display [tSC] (Water Temperature
Calibration). Using either the Up

⇑ or Down ⇓ arrow keys, calibrate the water

temperature sensor by increasing or decreasing the numeric value displayed to match the
water temperature reading measured on your thermometer. The control can be adjusted
to + 10

° or - 10° from the nominal displayed temperature. However, offset cal librations

greater than 3

° should be avoided…Such large offsets generally indicate problems with

the method of water temperature measurement, a water sensor not properly inserted in
well, or other equipment issues. Do NOT attempt to mask such issues through offset
calibration.

D. Once the corrected temperature is displayed, pressing the Pool / Spa Key will save the

newly displayed water temperature value, and will step to the controller to the next
service menu parameter: [dSC] , Defrost Sensor Calibration.

5. Defrost Sensor Calibration [dSC]…

In the event the Defrost Sensor requires calibration, the following steps must be followed
closely to insure optimal defrost control:

A. Turn the heater off;
