2.

Press the

TEST

 

button ( ) for 3 seconds so that [Maintenance mode] appears on the screen ().

 

After a while, [00] appears in the refrigerant address number display area.(at  )

3.

Press the

CHECK

 

button ( ) for 3 seconds to switch to [Maintenance monitor].

 

Note) It is not possible to switch to [Maintenance monitor] during data request in maintenance mode

 

(i.e., while “----” is blinking) since no buttons are operative.

 

[----] appears on the screen () when [Maintenance monitor] is activated.

 

(The display () now allows you to set a request code No.)

6.

Press the

FILTER

button () to perform function setting.

If above setting operations are done correctly, "Request code number" will appear in data display area.() [Example: When the "311" of "Request code number" is set, [311] appears on the screen.()]

[Refererence]

You can check current "request code number" setting by setting the "request code number"(“310” or “320”) and pressing the FILTER button.()

[Example: When the current setting is "Setting No.2(Request code 311)", [311] appears on the screen.()]

7. To return to normal mode, press the ON/OFF button ( ).

10-2. BACK-UP HEATING FUNCTION (CN152)
