Defective probes:
If a defective probe is detected, the defective probe pilot light turns on. The
room temperature shown on the display will then be the average value of
all temperatures measured by the probes remaining in proper condition and
the controller will operate according to this temperature.
To determine which probe is defective:
Set the parameter selection knob
to ROOM TEMPERATURE. The
room temperature appears on the
display.
Press the push-button. If the
probe connected to terminal #1
(supplied with the controller) is
not defective, the word "PR1" and
the temperature measured by the
probe will alternately appear on
the display. If the probe connected to terminal #1 (supplied with
the controller) is defective, the word "PR1" and the letter "P" will
alternately appear on the display.
For each additional probe connected to the controller:
Press the push-button once again. If the probe is not defective,
the word "PR#" (# is the number of the terminal to which the
probe is connected) and the temperature measured by the probe
will alternately appear on the display. If the probe is defective, the
word "PR#" and the letter "P" will alternately appear on the
display.
