ECONAVI TEST OPERATION
Preparation: Refer to the manuals of the indoor unit and turn
on the main power switch in advance.
Human detection cannot be made for approx.
90 seconds when switched on the power
because the human detection sensor is set in
initial setup.
1. Press three buttons.
Keep pressing the
, and buttons
simultaneously for more than 4 seconds.
The “Maintenance func” menu appears on the screen.
2.
Select “0. ECONAVI info.” from the menu command.
By pressing the / buttons, select
“0. ECONAVI info.” and press the button.
3.
Select “Error found” from the menu command.
By pressing the / buttons, select “Error
found” and press the
button.
4.
Check the sensor status shows “Normal”.
(By pressing the / buttons, the status of
each indoor unit can be scrolled on the screen.)
The sensor status of all indoor units are displayed.
• “Normal”: The sensor on the panel for cassette
(ECONAVI type) works normally.
• “Preparing”: The sensor on the panel for cassette
(ECONAVI type) is set in initial setup.
Confirm that “Normal” appears within 90 seconds.
• “Unsupported”: Indoor units not available for ECONAVI
function.
The test run procedure described above is over. If any
display appears other than “Normal” or “Preparing” even
though the ECONAVI panel is connected, follow the Step 5
below.
* “1-1”, “1-2” mean indoor unit No. If the indoor unit is without
ECONAVI panel, “Not connected” appears.
* “Sensor 1” means optional ECONAVI sensor
(CZ-CENSC1). If not connected, “Not connected” appears
besides “Sensor 1” on the screen.
5.
If the sensor status shows other than “Normal”,
“Preparing”,
If the sensor status shows “Error” or “Not connected”
although the panel for cassette (ECONAVI type) is
connected, the following symptom may have occurred.
Specify the applicable indoor unit and check the sensor.
“Error”: The sensor may possibly be damaged.
”Not connected”: The wiring between the indoor unit and
sensor may possibly be disconnected.
* The specified indoor unit can be confirmed by the flap
operation.
Confirmation method:
1
Finish the maintenance function.
Press the
button to show the maintenance
function display and then press the
button.
2
Operate the flap.
By pressing the
button, select the applicable
“Indoor Unit No.” in the list of “2. FLAP” and then
make flap setting. The indoor unit which responds to
the flap setting becomes available.
When the indoor unit is specified, turn off the main
power switch and disconnect the connector of sensor
wiring from the PCB. Then reconnect it. Turn on the
main power switch and repeat the Steps 1 to 4 described
above. Confirm the display shows “Error found”. If the
display shows “Error” or “Not connected” on the screen
again, it is necessary to replace the panel for cassette
(ECONAVI type) with a new one.
This is an example of the combination systems which extract optional output signal by the service wire and relay (field supply).
When actuating the external device interlock, use the thermostat signal.

distance of 2 m or less from the PCB.
The external output signal from the air conditioner is supplied for the purpose of controlling the external devices. If the air
conditioner does not operate, take measures that the movement of external connecting devices can transfer to the safety
zone in advance.
The external output signal from the air conditioner is turned off when the blackout occurs. If any special considerations are
needed in case of blackout, provide an external circuit.
Use the thermostat signal.
