1. Verify that probe wires and quick
disconnect are secure in control.
2. Check probe resistance to table
below. If 0 resistance is present
check wiring insulation. If infinite
resistance is present check for breaks
in wiring (meter will likely read
overload or very high in the mega-
ohm range).
3. Ensure that probes are wired per the
wiring diagram provided.
4. Replace probe if other remedies fail,
or if probe resistance deviates from
"Error! Reference source not
found." Error! Reference source
not found.
1. Remedy abnormal operating
conditions. The control is rated to
operate in a range of 14 to 122° F (-10
to 50° C) and less than 90%RH non-
condensing.
2. Replace control if problem persists.
