accessed. The first parameter of the selected menu is displayed on the screen.
N
- Press
key to access the next parameter and key to return to the previous one.
P
- Pressing
, key, the controller returns to the LEVEL 1 MENUS.
Level 3 Values
- To DISPLAY the CURRENT VALUE of any parameter, select the required one and press
Once it is displayed, you can CHANGE VALUE, pressing
- Press SET key to ACCEPT THE NEW. The programming returns to LEVEL 2 PARAMETERS.
P
- Pressing
, key, the controller returns to the LEVEL 2 PARAMETERS.
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.
