11 Figure 4: Keypad Keypad Imput Keypad inputs The control accepts user inputs via the keypad on the front panel. 1. When changing the mode from "STANDBY" to either "SPA" or "POOL" there may be up to a 10second delay for the blower fan to begin running. The control performs an internal self-test and then verifies that the blower vacuum switch contacts are open before energizing the blower. 2. It is normal for the heater to display a 1- to 2-second delay in responding to any keypad input. 3. It is normal for the heater to display up to a 5-second delay when the keypad is used to reset the control to clear an error code. 4. The control will accept a mode change during lockout after 5 seconds. The control will continue to display the error code and remain in lockout until it is reset. At reset the control will go to the last saved mode. Operation: Set point adjustment: The set point temperature is displayed by pressing the "UP" or "DOWN" buttons while in "POOL" or "SPA" mode. The set point will blink while it is displayed. Further pressing of the "UP" or "DOWN" buttons will adjust the set point temperature up or down as desired. The set point range is between 65°F (18°C) and 104°F (40°C). Fahrenheit versus Celsius: The temperature can be displayed in Fahrenheit or Celsius. TO change the display, use the "MODE" but- ton to place the heater in "STANDBY". Then press and hold the "UP" and "MODE" buttons until the display shows the °F/°C selection. Press the "DOWN" button to toggle between selections. To accept the selection, press the "MODE" button. If the user does not act, the selection will be automatically accepted after 60 seconds. Winterization: In moderate climates, the heater can continue to operate during short-term cold spells. Do not use the heater to maintain the water temperature just above freezing or for freeze protection. Care must be taken to avoid freeze-up in the heater. When it is used during freezing weather, the pump must run continuously. The heater is not warranted against freeze-ups. In regions where freezing temperatures are encountered, all water must be drained from the heater when it is out of service, to prevent damage to the heater and piping. Draining the heat exchanger is recommended as part of the season's shutdown procedures.
