Functional Description
1.4
Simulated Operation Function
RZQ71C7, RZQS71·100C7
When a malfunction on one of the below thermistors occurs, operation will continue while
displaying the applicable alarm on the remote-controller. Fin thermistor malfunction is only
displayed when pressing the "Inspection" button on the remote controller.
· Outside temperature thermistor
· Outdoor heat exchanger thermistor
· Fin thermistor
· Discharge pipe thermistor
· Indoor unit air suction thermistor
· Indoor heat exchanger thermistor (RZQ71C7, RZQS71·100C7)
Note:
Simulated operation will not be conducted in case the below mentioned thermistors are
malfunctioning:
· Suction thermistor
· Indoor heat exchanger thermistor
· Outdoor heat exchanger thermistor
RZQ100~140C7·RZQS125·140C7
In case of a thermistor malfunction, simulated operation is performed in two different ways
as shown below even while the malfunction is detected.
A. Operation continues while the malfunction code is displayed on the remote controller.
Applicable thermistors
· Outside air temperature thermistor
· Heat exchanger distribution pipe thermistor (in cooling operation only)
· Intermediate heat exchanger thermistor (in heating operation only)
· Liquid pipe thermistor
· Indoor suction air thermistor
· Indoor heat exchanger thermistor
B. Operation continues even the malfunction is detected. The remote controller displays
"Inspection/Test Run". Only when the button is pushed, the malfunction code appears.
Applicable thermistors
· Remote controller thermistor
· Radiation fin thermistor
Note:
In case of a thermistor malfunction other than A and B above, a malfunction stop is made and
no simulated operation is carried out.
Applicable thermistors
· Suction pipe thermistor
· Discharge pipe thermistor
· Heat exchanger distribution pipe thermistor (in heating operation only)
· Intermediate heat exchanger thermistor (in cooling operation only)
