Temperature Sensor
The system is constantly verifying that the reading of the temperature probe is within limits. If the actual spa water
temperature greatly differs from that displayed by the spaside control or if 32
°
F is constantly displayed, this indicates
a problem with the water temperature sensor.
Note that the temperature of the water should be over 35
°
F to perform the following steps.
Press a key after each step to reset the system.
Power can remain On.
·
Verify that the temperature sensor is
properly connected to the printed circuit
board.
·
Disconnect the sensor connector and
try and clean the connector pins. A
small coating of film can cause a bad
connection. Also inspect for bent pins.
·
Reconnect the sensor.
·
If the display is still unchanged on the
spaside control, replace the sensor with
a spare and place the probe in the spa
water.
·
If this solved the problem, replace the
sensor. Replace the printed circuit
board if the problem has not been
corrected.

High Limit Sensor / Over Heat
If 3 flashing dots appear on the spaside control and the LED error indicator on the printed circuit board
is
illuminated,
there is either a problem with the high limit temperature sensor or an over heat condition has occurred. This will
happen whenever the water temperature read by the high limit temperature sensor exceeds 115
°
F.
Power to the system must be turned off then on to reset the system.
Power can remain On.
If the reading is
below 115
°
F:
·
With an accurate thermometer measure
the temperature of the water.
·
Check to see if the heater housing is
hot.
·
If the heater housing is hot, check for an
obstructive flow of water (closed valves or
dirty filter).
·
If after clearing any obstructions the
error still appears on the display and the
LED error indicator is still illuminated on the
printed circuit board, replace the printed
circuit board.
