Defective Probes
Room Probes
If one or both room probes are defective, the defective probe pilot light turns
on. If both room probes are defective, the display shows the letter "P" when
the parameter selection knob is set to ROOM and the controller
operates according to the minimum ventilation cycle (
"Minimum ventilation cycle", page 24). Otherwise, the display shows the
value of the temperature measured by the remaining room probe and the
controller operates according to this temperature.
To identify the defective probe:
•
Set the selection knob to ROOM . The room
temperature is displayed.
•
Press the push-button. If the probe connected
to terminal # 1 is not defective, the letter "A" is
displayed, alternating with the temperature
measured by probe A. Otherwise, the letter
"A" is displayed, alternating with the letter "P".
•
Press the push-button. If the probe connected to terminal # 2 is not
defective, the letter "b" is displayed, alternating with the temperature mea-
sured by probe B. Otherwise, the letter "b" is displayed, alternating with the
letter "P".
