Pipe/Roof Sensor Faults

The following are error messages caused by pool or roof sensor faults;
FAULT
SENSOR DISCONNECTED
SENSOR SHORT CIRCUIT
ISOLATING
SENSOR FAULTS
REASONS/SOLUTIONS
Power point is faulty; test power point with known working appliance. If the power point
is operational, check the controller with another power point and if there is still no display,
then send the controller for repair.
REASONS/SOLUTIONS
Sensor cable unplugged from controller, cable damaged, bad cable join.
Sensor cable damaged, bad cable join.
Swap the sensor locations; simply put the pipe sensor in the roof socket and the roof sensor
in the pipe socket.
If the fault moves from pipe to roof or vice versa, then you can be certain that there is a
sensor fault. If the fault remains the same then the controller will need repair.
For sensor disconnected or short circuit faults, check for damage to the cable and repair if
required. If no damage can be found, replace the sensor. If the cable runs underground or
inspection is not possible, then cut the sensor from near the end of the cable and strip back
the wires and join them. If the controller reports a short circuit, then the cable is fine and you
may replace the sensor end if re-routing a new cable is not possible.
If the controller reports a short circuit while the cable is unplugged, then the controller
requires repair.
