This light indicates that the heater has control power.
WARNING: This is not a supply line power indicator and caution should be used since
more than one power disconnection may be required to isolate the heater electrically.
WARNING: If the optional Time Clock Override is installed, you must shut off the
water pumps main power disconnect as well to eliminate all power to the heater.
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 at the same time in order for the heater to run.
LED READOUTS:
When the unit has power, the LED will display the current water temperature. When
pressing the thermostat buttons the flashing readout will indicate the set temperature.
The following are LED code readouts for the internal sefety controls that regulate
the unit for various reasons.
LF = LOW WATER FLOW
This light indicates there is no water flow through the heater. The heater is
designed to shut off whenever 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. During normal
operation the heater turns off and on with the water pump. LF will be displayed
whenever the water pump is off.
DF = DEFROST MODE
This readout indicates that the internal defrost safety control has disabled the
heater. During cold weather where the air temperature drops below approxi-
mately 45 to 50 degrees (depending on humidity), the low refrigerant pressure
switch (or defrost control) is designed to disable the compressor only. Once
the unit is in defrost mode the compressor will shut off for 1 hour while the fan
continues to help deice and warm the air coil. After 1 hour the unit will attempt
to restart. If the air temperature has increased to the operational range the
compressor will continue to run, otherwise the compressor will return to the defrost
mode for another 1 hour delay cycle.
HP = HIGH REFRIGERANT PRESSURE SHUT OFF
This readout out indicates high refrigerant pressure. The high refrigerant pres-
sure 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. The only way to reset the unit after HP is
displayed is to shut the unit off then back on with the heater button.
TIME DELAYS:
30 second compressor delay when switching pool/spa modes.
5 minute compressor delay when T.C.O. enables in pool mode.
5 minute T.C.O. off delay when: switching from spa to pool mode, when temperature
is reached in pool mode, or if LF (low water flow) is displayed on LED.
If water pump loses prime there will be a 3 minute compressor delay.
