E. "DIGITAL LOGIC" CONTROL PANEL INFORMATION

POWER button is lit when heater is turned on.

3. MODE SELECT BUTTONS-POOL or SPA: The heater has two thermostat modes for two dif-

ferent 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.

6. OPTIONAL WATER PUMP TIME CLOCK OVERRIDE OPERATION When the T.C.O.

button is set to the ON mode, the Time Clock Override feature is designed to start the water pump

when the pool requires heat. Once the pool is up to the set temperature the heater will stop and

then 5 minuets later the water pump will stop. When this button is set to the OFF mode, the heater

will operate only when the water pump is running during the timed period set on the time clock.

NOTE: The time clock override works best if used during cooler weather conditions where the pool

is losing more than 8 to 10 degrees over night or when the pool is being heated from "dead cold".

NOTE: If the time clock override starts the water pump and the thermostat does not continue to

call for heat for at least 5 minutes, the control will shut the water pump and heater off. Thereafter,

it will not re-attempt to start the water pump for 4 hours. This 4 hour delay can be bypassed by

pressing the T.C.O. button off then back on. NOTE: When the T.C.O. button is activated while in

"spa mode" the water pump will run the entire time you are in spa mode. When you switch back

to pool mode there will be a 5 minute delay before the water pump shuts off.

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 humid-

ity), 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.

LED READOUT:

1. GREEN POWER LIGHT: This light indicates that

the heater has control power. WARNING: This is not

a line power indicator and caution should be used since

more than one power disconnection may be required

to isolate the heater electrically. If the optional Time

Clock Override is installed, you must shut off the water

pumps main power disconnect.
