Daikin EWWD800CJYNN [23/28] Upload from programming key

Upload from programming key

To upload the program using the programming key (cod. 129150106), it is necessary to first upload the program to the

key and then to upload it into one ore more controllers. The same procedure has to be used for both operations, just

selecting the correct position of the key switch:

The procedure is described as follows.

• disconnect the controller from pLAN and set the net address to 0.

• select the right key switch position

• insert the key in the “expansion memory” connection (remove the cover if necessary)

• press “up” and “down” keys at the same time and switch on the controller

• press “enter” key to confirm the operation

• wait until the controller boots up

• turn off the controller

• remove the key

In case no controller with an installed programme is available, the key may be programmed using the same procedure

described for the direct upload from a PC. In this case, with the key inserted in the controller and the key switch in

position 2 (red light), the program will be written on the key instead of on the controller.
