- In the desired menu of LEVEL 1 MENUS,
press
key. LEVEL 2 PARAMETERS
programming is accessed. The first para-
meter of the selected menu is displayed
on the screen.
- Press
key to access the next parame-
ter and
key to return to the previous
one.
- Pressing
key, the controller returns to
the LEVEL 1 MENUS
REMARK: If no key is pressed for 25 seconds in either of the previous steps, the controller
will automatically return to the CURRENT TEMPERATURE display status without modifying
any of the parameters values.
