Return
Air
EGO
Overheat
1. Drying heating closes when alarm rings,
and it is automatically reset after faults are
removed.
2. The part is detected after being electrified,
and error occurs when the return air EGO
overheat input signal proves to be effective
and delays for 2 secs.
Check whether the setting of [regenerative EGO
overheat] and that of
“
normally open
”
and
“
normally close
”
of overheat signal are correct or
not.

timed cooling
”
when alarm rings, and it is
manually reset after faults are removed.
2. Error occurs when the rotor can
’
t be
detected in the [rotor monitoring time] and the
valid time of its input signal exceeds 10 secs.
Set the parameters according to the rotor
conditions: time for the rotor to run a cycle [rotor
monitoring time], and set aside a certain volume.
If you want to disable this alarm, you can set the

”
or reset by re-powering on.
Regenerative
Probe
Error
1. Regenerative heating closes when alarm
rings, and it is automatically reset after faults
are removed.

and error occurs when there is something
wrong with the probe.
Examine the wire and check whether the probe
matches with the controller.
Drying Probe Error
1. Drying heating closes when alarm rings,

Return Air Probe Error
1. Drying heating closes when alarm rings,
and it is automatically reset after faults are
removed.
2. The part is detected after being electrified,
and error occurs when there is something
wrong with the probe.
Examine the wire and check whether the probe
