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

press the [POOL/SPA] key until the display shows [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 controller can be adjusted to +10

o

F to –10

from the nominal displayed temperature. However, offset calibrations greater than 3

o

F

should be avoided… Such large offsets generally indicated problems with the method of
water temperature measurement, a water sensor not properly inserted into the well, or other
equipment issues. Do NOT attempt to mask such issues through offset calibration.

D. Once the corrected temperature is displayed, Not pressing depressing 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 [dSC], (Defrost Sensor Calibration).

In the event the defrost Sensor requires calibration, the following steps must be followed closely
to ensure optimal defrost control.

A. Turn the heater off at the main circuit panel.

B. Remove the unit’s front panel to gain access to the defrost sensor. The defrost sensor will

be found strapped to the suction line in combination with the TXV bulb on heat only models,
or on the evaporator’s suction heater independent from the TXV bulb for heat and cool
models.

C. Carefully remove the insulation from around the sensor area.

D. Using a highly accurate, surface-mount thermometer, attach the thermometer probe to  the

suction line immediately adjacent to the Defrost Sensor. After the thermometer probe is
securely attached to the suction line, reinstall the insulation foam around the sensor.

E. With the foam insulation and the front reinstalled, restart the unit, allowing it to run for 10-

minutes… The suction line temperature should have stabilized at this point… Note the
suction line temperature as measured by the thermometer probe.

F. Follow previous steps “1a.” through “1d.,” to enter the service menu. Once [dEL] is

displayed, press the [POOL/SPA] key until the display shows [dSC] (Defrost Sensor
Calibration). With the service menu parameter [dSC] displayed pressing either the [UP] or
[DOWN] arrow key once will display the current temperature value of the defrost sensor.

G. Compare the controller’s displayed defrost sensor temperature with the reading on the

thermometer. If the 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. The controller can be adjusted

to +10

o

F to –10

o

F from the nominal displayed temperature. However, offset calibrations

greater than 3

o

F should be avoided… Such large offsets generally indicated problems with

the method of suction line temperature measurement, a defrost sensor not properly
attached to the suction line, or other equipment issues. Do NOT attempt to mask such
issues through offset calibration.
