What to do if Low Water Lockout
Occurs with New Sensor
1. Turn off power to the control.
2. Remove sensor from well and disconnect green
sensor wire.
Leave the main sensor cable
connected to the control.
3. Being careful not to allow the sensor or the green
wire to touch anywhere in the terminal area of the
control, restore power to the control. Within 30
seconds the AquaSmart control should enter into
Lockout Water Low.
LOCKOUT
WATER LOW
4. Use the 1,000 Ohm resistor attached to this
instruction sheet. Place one resistor lead on the
metal pin of the sensor, the second resistor lead
should be on a metal portion of the connector for
the green wire coming from the sensor (see pictures
below). Hold the resistor in place with fingers.
Within 30 seconds the Lockout Low Water fault on
the display should clear.
If the Lockout Low Water
clears, the sensor is operating properly.
Other Possible Causes:
•
Poor connections in the LWCO circuit wiring
•
Deposit build up on the well or boiler vessel
•
Conductivity issues with the water.
5. Recheck the continuity of the LWCO circuit following
the procedure on the previous page.
6. If the sensor is good and the LWCO connection
wiring is good, drain water from the boiler, remove
the well and check for deposit build up on the well.
Clean if necessary and reinstall the well. Refill the
boiler. Check for proper operation of the LWCO
circuit.
7. If the sensor, LWCO connection wiring and well are
good, attempting to measure the resistance through
the water may provide some indication of the
conductivity of the water in the system. Remove the
sensor from the well. Place one of the ohm meter
probes on the metal tube inside the well and place
the second probe on the metal of the boiler vessel.
•
100K ohms or above - water not in contact with
well, deposit build up in boiler vessel
•
5K-100K ohms - intermittent operation could
occur
•
5K ohms or below - LWCO should operate
These are rough guidelines only.
