F. "DIGITAL LOGIC" CONTROL PANEL INFORMATION
The heater has two thermostat modes for two different desired temperature settings, one for
pool mode and one for spa mode. If you do not have a spa, use the pool mode only. If you
have a spa/pool combination, you have options available to automate pool and spa heating
functions.
4. THERMOSTAT BUTTONS: Pressing the + button will raise the set temperature. Pressing
the - button will lower the set temperature. When either button is pressed the LED display
will begin to flash. The flashing numbers indicate the thermostat setting.
5. GREEN HEATING LIGHT: This light indicates that the unit is heating and the compressor
is running. The compressor starts after a 3 to 5 minute time delay. NOTE: The water pump
must be running in order for the heater to run.
LED STATUS CODE READOUTS:
LF This light indicates there is no water flow through the heater. The heater is designed to shut
off when the water pump is not pumping water through the heater. If LF is on while the water
pump is running, the water pump may not be supplying enough flow for the heater to operate
properly.
DF This readout indicates that the internal defrost safety control has disabled the heater. During cold
weather where the air temperature drops below approximately 45 to 50 degrees (depending on
humidity), the defrost sensor is designed to disable the compressor only. When the air temperature
has increased to the operational range the compressor will come on and start heating again.
HP This readout out indicates high refrigerant pressure. The high refrigerant pressure switch is
designed to shut the compressor and fan off if a heat buildup occurs for whatever reason. Typically
the high refrigerant pressure switch will trip if the water flow through the heater is restricted. It
may also trip if the air flow is restricted through the heater. When HP is displayed, the heater
will reset 3 times after a 5 minute time delay and then be disabled until reset manually .
To reset, turn the unit off then back on.
