START UP & SETTING OPERATING CONTROLS LEVEL-1 (Owner) ACCESS NOTE: Covered within this section are features and settings typically accessed first by the installer, and then remaining accessible by the end user (owner). These features reside at the Level-1 access point within the microprocessor. (Please see page-11 for information concerning Level-2, service-related access.) 1. Applying Power to The Controller: A.
5. Changing The Pool Temperature Set Point: A. Using the Pool / Spa key, select the POOL temperature set point. The pool set point indicator light will confirm your selection by lighting. B. The pool temperature set point range is adjustable from 60°F. to 95° F (104 °F in latest models). using the Up ⇑ or Down ⇓ arrow keys. The desired temperature can be selected by briefly depressing the arrow keys, or by holding them down to scroll the temperature up or down. 6.
5) With [ELC] displayed, use the Up or Down arrow keys to select a lock code number. The factory set lock code is “17”. Not depressing any buttons for 15seconds will allow the control 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 [CFO] (Call Flex Options); 6) Once the ULC option has been enabled, depressing any key will display [000] (prompting the entry of the correct lock code number).
10. Fan Speed Control… This option is not applicable to any current models. If option present, factory default setting of “80” MUST remain. Controllers Version .06 or newer will not contain a FAN option. LEVEL-1 DISPLAY CODES Menu Codes Description Function [FLO] No water flow Displayed Code Message: Appears whenever the circulating detected pump is off, or when the heater is not receiving correct water flow.
WARNING !!!! Dealer & Service Center Use Only SERVICE & SET UP FEATURES LEVEL-2 ACCESS (Includes Configuration for External Controllers) 1. Entering Service Menu: A. To enter the service menu level, depress and hold both the Up ⇑ and Down ⇓ arrow keys simultaneously until the code message [CF1] (Celsius Fahrenheit Selection) is displayed. (NOTE: If [000] displays, User Lock Code is enabled, and the ULC pass code must be entered before proceeding.
WARNING !!!! Dealer & Service Center Use Only 3.2: Configuring for External Controllers not Equipped with an “OFF” Position 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.
WARNING !!!! Dealer & Service Center Use Only B. Remove the unit 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 sensing bulb, or, in some models, the defrost sensor will be connected to the suction line independent of the TXV bulb; C. Carefully remove the insulation from around the sensor area; D.
WARNING !!!! Dealer & Service Center Use Only 7. Changing Service Lock Code & “Backdoor” Entry… A. Changing the Code… The factory default Service Lock Code is “50”. Service personnel are strongly advised to retain the factory default setting. However, should unauthorized access to the Level-2 (Service) menu be suspected, it may be useful to select a code other than “50”.
WARNING !!!! Dealer & Service Center Use Only 8) [DEL] will display (At this point you have entered the service menu, and servicelevel programming will be possible.); 9) Push Pool/Spa pad until [LOC] appears on readout for the second time; 10) Push the up arrow,…The current, correct lock code will display. Using the up or down arrow, the code can now be changed back to back to the factory default: “50”, or the code may be set to any number ranging [000] to [999].

Dealer & Service Center Use Only LEVEL-2 FAULT CODES Message Error Description [dPO] Defrost Sensor Open Water Temperature [PO] Sensor Open [dPC] Defrost sensor shorted Water temperature [PC] sensor shorted Refrigerant system [LP] low pressure switch open Refrigerant system [HP] high pressure switch open [FLO] Low or no water flow detected Heater in defrost [FS] mode [CSE] Control system error Possible Cause Cut or loose sensor wiring Cut or loose sensor wiring Short circuit in defrost senso
WARNING !!!! Dealer & Service Center Use Only APPENDIX Connecting to, and Configuring Microprocessor for, External Control: • A: Jandy and Pentair/Compool Brand External Controllers Equipped with an “OFF” Position • B: External Controllers NOT Equipped with OFF Setting • C: Remote Flow Switch Connection • D: Call/Flex Option 18
WARNING !!!! Dealer & Service Center Use Only Connecting Specific Jandy Or Pentair/Compool Controllers (See application table within) Appendix- A Instructions For Connecting Specific Jandy Or Pentair/Compool Controllers To AquaCal’s HP7 Microprocessor The microprocessor terminal block, labeled X,Y,Z, is located on the low-voltage portion of the MICROPROCESSOR POWER BOARD. (See figure 1, below.) Figure-1 Controllers Suitable for this Application: Jandy and Compool controllers have similar features.
WARNING !!!! Dealer & Service Center Use Only Warning ! MAKE CERTAIN POWER SUPPLY TO HEATPUMP and CONTROLLER IS DISCONNECTED PRIOR TO CONTINIUING. FAILURE TO DISCONNECT ELECTRICAL POWER MAY RESULT IN SERIOUS INJURY OR DEATH. 1. String 18/2 cable from the controller to the heat pump. 2. Locate the MICROPROCESSOR POWER BOARD inside the heat pumps electric box. (See figure 1) 3.
WARNING !!!! Dealer & Service Center Use Only Warning ! MAKE CERTAIN POWER SUPPLY TO HEATPUMP and CONTROLLER IS DISCONNECTED PRIOR TO CONTINIUING.
