Memory Card
The memory card is used to create a backup
copy of your controller’s configuration. The
card is also useful to transfer the configura-
tion of one controller to another controller of
the same type.
The switch at the bottom of the card is used
to lock or to unlock the card ( = locked,
= unlocked).
Turn off power each time you open the
controller’s enclosure. This prevents
accidental exposure to areas of high
voltage.
TO TRANSFER A CONFIGURATION:
1. Open the latch and lift the controller's
cover.
2. If you are about to copy the controller's
configuration on the memory card, make sure
the card's switch is at the unlocked position.
3. Insert the card in the connector located
on the electric board inside the controller.
Refer to the illustration above to position the
memory card correctly.
4. If internal switch #12 is at
the OFF position, simply switch
it to the ON position; if internal
switch #12 is already at the ON
position: switch it back to OFF
and then ON again.
5. Close the controller's enclosure.
6. The transfer menu should be displayed on
screen. Use the adjustment buttons to select
whether you want to transfer the memory
card's content into the controller (
"COPY"
"to" "CTRL"
)
or if you wish to transfer the
controller's content into the memory card
(
"COPY" "to" "CARD
") .

7. Once you have chosen the proper type of
transfer, press and hold the Other Functions
button for 5 seconds. The controller will au-
tomatically return to the
ROOM TEMP
menu
once the transfer is completed. If the transfer
is incorrect, the letters
"COPY"
and
"Error"
will flash on screen. In this case, press the
up or down adjustment button to exit the
error menu and then refer to the table below
to see possible error causes.
8. Once the transfer is over, open the con-
troller's cover, and remove the memory card
from the connector. Close the controller's
enclosure afterwards.
9. Lock the card switch ( ) if required.
