TEMPERATURE CONTROLS: The top Thermostat controls the pool temperature. The
bottom Thermostat controls the spa temperature. If you do not have a spa you can use
the two thermostats as a high and low temperature preset.
THERMOSTAT/OFF SWITCH- POOL/OFF/SPA: The Thermostat/Off Switch determines
which thermostat is active, up for pool, down for spa. You can disable the heater by
placing the selector switch in the center "OFF" position.
GREEN POWER LIGHT: This light indicates that the heater has control power. WARN-
ING: 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. WARNING: If
the optional Time Clock Override is installed, you must shut off the water pumps main
power disconnect as well.
BLUE HEATING LIGHT: This light indicates that the unit is heating and the compressor
is running. The compressor starts after a 5 to 7 minute time delay. NOTE: The water
pump must be running at the same time in order for the heater to run.
AMBER NO WATER FLOW LIGHT: 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 this light 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, (as long as the
thermostat is calling for heat).
RED FAULT LIGHT: This light indicates that the internal safety control system has dis-
abled the heater. If either the high or low refrigerant pressure switch has tripped this
light will come on. NOTE: During cold weather where the air temperature drops
below approximately 45 to 50 degrees (depending on humidity), the low refrig-
erant pressure switch (or defrost control), is designed to disable the heater. In
this "defrost mode" the fan and compressor will shut off. When the defrost
switch resets for whatever reason the fan will restart, then after a 5 to 7 minute
time delay the compressor will attempt to restart. In some case where the air
temperature are in a borderline range, the heater my cycle on & off in an at-
tempt to reset. The heater should be shut off when the air temperature is ex-
pected to drop below the operational range for an extended period. The high
refrigerant pressure switch is designed to shut the compressor and fan off if a heat
buildup occurs for what ever 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.
NOTES: The heater will never run without water running through it from the filter pump.
The heater will not heat faster if you turn the thermostat knob up higher.
