Taylor Pool Heat Pump owner manual To Enter The Service Mode, c. WATER SENSOR CALIBRATION

Another mode exists which permits the service technician to modify the calibration of the sensors as well as different control parameters.

TO ENTER THE SERVICE MODE:

To access the service mode hold the [SET] key for 3 seconds. The set mode LED will come on to indicate the set mode. Now hold both the [^] and the [v] key simultaneously for 3 seconds. The service mode LED will come on to indicate the service mode. In the service mode, unlike the set mode, the control does not return automatically to the normal mode 8 seconds after the last key was touched. To exit the service mode you must step through the parameters until you come to the setpoint adjustment mode ( see i. on page 9 ). The first parameter is the water sensor calibration.

c. WATER SENSOR CALIBRATION:

The digital display will show [CXX]. «C» represents the water sensor calibration mode. «XX» is the actual water temperature in °F. If water sensor calibration is necessary, measure the water temperature with a precise digital thermometer and adjust the digital display to show the same value using the [^] and the [v] key. To view or step to the next parameter (defrost sensor calibration), touch the [SET] key.

d. DEFROST SENSOR CALIBRATION:

The digital display will show [cXX]. «c» represents the defrost sensor calibration mode. «XX» is the actual defrost temperature in °F. If defrost sensor calibration is necessary, measure the temperature of the defrost sensor, installed on the side of the evaporator, with a precise digital thermometer and adjust the digital display to show the same value using the [^] and the [v] key. To view or step to the next parameter (defrost cut-in temperature), touch the [SET] key.

e. DEFROST CUT-IN TEMPERATURE ADJUSTMENT:

The digital display will show [LXX]. «L» represents the defrost cut-in temperature adjustment mode. The defrost cut- in temperature is the temperature of the evaporator at which the defrost sequence is initiated. «XX» is the defrost cut-in temperature in °F. This adjustment is factory set at 30 °F. If it is necessary to change this adjustment, adjust the digital display to show the desired value using the [^] and the [v] key. The range of this adjustment is from 10 °F to 60 °F. To view or step to the next parameter (defrost cut-out temperature), touch the [SET] key.

f.DEFROST CUT-OUT TEMPERATURE ADJUSTMENT:

The digital display will show [HXX]. «H» represents the defrost cut-out temperature adjustment mode. The defrost cut-out temperature is the temperature of the evaporator at which the defrost sequence is terminated. «XX» is the defrost cut-out temperature in °F. This adjustment is factory set at 48 °F. If it is necessary to change this adjustment, adjust the digital display to show the desired value using the [^] and the [v] key. The range of this adjustment is from 10 °F to 60 °F. To view or step to the next parameter (deadband adjustment), touch the [SET] key.

g. DEADBAND OR TEMPERATURE DIFFERENTIAL ADJUSTMENT:

The digital display will show [bXX]. «b» represents the deadband adjustment mode. The deadband is the differential between the cut-in and cut-out water temperatures. «XX» is the differential in °F, This adjustment is factory set at ±0.4 °F ([b0.4] on the display). If it is necessary to change this adjustment, adjust the digital display to show the desired value using the [^] and the [v] key. The range of this adjustment is from ± 0.1 °F to ± 1.0 °F. To view or step to the next parameter (compressor defrost delay-off time adjustment), touch the [SET] key.

h. COMPRESSOR DEFROST DELAY-OFF TIME ADJUSTMENT:

The digital display will show [dX.X]. «d» represents the compressor defrost delay-off time adjustment. The compressor defrost delay-off time adjustment is the time that the compressor continues to operate after the defrost temperature falls below the defrost cut-in temperature (ie. 30 °F) «X.X» is the delay time expressed in hours and fractions of hours. This adjustment is factory set at 1.0 hour ([d1.0] on the display). If it is necessary to change this adjustment, adjust the digital display to show the desired value using the [^] and the [v] key. The range of this adjustment is from 0.1 hours to 1.5 hours. To view or step to the next parameter or to exit the service mode (setpoint

adjustment), touch the [SET] key.

i. TO CHANGE THE SETPOINT TEMPERATURE OR TO EXIT THE SERVICE MODE:

Touch the [^] key to increase the setpoint or the [v] key to decrease the setpoint. The adjustment range is from 70 °F to 105 °F (21 °C to 41 °C in the °C mode). You have 8 seconds from the time that the last key was touched to make the adjustment. After 8 seconds the set mode LED will go off and the control will exit the service mode and return to the normal mode.
