High probe signal* -- 0 4000 counts
Systems using tap or softened water control water levels
electronically using a three-rod probe. The controller initiates the
following events when the probes are in contact with water:
High probe: Fill valve closes
Mid probe: Fill valve opens
Low probe: Low water cut-off
The display indicates the probe is in contact with water by indicating
“Water” or “No water.”
The high, mid, and low probe signal counts, displayed on the Status
screen, indicate:
<800 = Probe is properly reading water
800-1200 = Faulty water probe (causes a “Faulty water probe”
alarm) 1200-1600 = Probe requires maintenance (causes a “Clean
probes” message)
>1600 = Probe is dry
