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 ( refer to

defective, the letter "b" is displayed, alternating with the temperature mea-
sured by probe B. Otherwise, the letter "b" is displayed, alternating with the
