SYMPTOM

CAUSE and REMEDY

Lo is
continually
displayed

−

Temperature is below minimum
(13.5°F or -10.0°C).

Hi is
continually
displayed

−

Temperature is above maximum
(105.0°F or 41°C).

−

Probe is short circuited.

Fan(s) or
heater not
operating

−

Verify whether the fan LED is on. If
LED is on yet fan or heater is not
operating, verify wiring, fan and fuse.
Refer Figure 6 for fuse location. If fuse
is blown, replace with fuse of same
type.

Stage 5 Fan
or Heater is
operating
erratically

−

Verify that the software setting switch
located at the rear of the faceplate is
properly set.

−

Verify the minimum rating (10mA at
230V or 20mA at 230V.

Display is
blank

−

Verify that the line voltage selector
switch is properly set.

−

Verify that the 10 pin flat cable
between the main board and the
faceplate board is connected.

F2 displayed
for relative
humidity

−

Humidity is below minimum (30%).

−

Probe is disconnected or defective.
