Probe damage alarm
A temperature probe is damaged
or disconnected.
Replace or reconnect the
temperature probe. The control
should recover automatically.
If another probe is available, the
control uses it. If probe averaging
is on, the defective probe is
excluded from the average. For
more information, read
Configuring temperature probes
on page 31.
pdeu
Probe deviation alarm
The difference in measured
temperatures between averaged
probes is greater than 18°F (10°C).
Check the temperature probes.
Check to see if a cooling or
heating element has failed.
Check the alarm setting. For
more information, read
Programming alarm settings
on page 58.

Actuator jam alarm
The third digit shows which
actuator (1 or 2) the alarm is
for.
The control is attempting to open
or close an inlet or other element
operated by an actuator, and has
not received the correct response
from the positioning motor.
Check the element controlled by
the actuator to see if it is
mechanically stuck.
Check feedback wires for
damage or improper installation.
For more information, read
Determining correct actuator
feedback wiring
on page 82.
Recalibrate the actuator. For
more information, read
Calibrating actuators on page
35.
err1
Error 1 - Growth curve error
The temperature set points for the
growth curve are increasing or
overlapping.
Temperature set points must
decrease as the curve steps
increase.
Change the temperature set
points so that they decrease. For
more information, read
Programming the growth
curve
on page 43.
err2
Error 2 - Actuator error
The temperature set points for one
of the actuators are overlapping.
The differential for step 1 must be
lower than the set point for step 2,
and so on.
Check the actuator settings and
make sure they do not overlap.
For more information, read
Programming actuators on
page 49.
err3
Error 3 - SAVER error
The PEC+SAVER is not in place
when trying to save or restore
settings
Make sure the PEC+SAVER is
inserted correctly and then try
again.
