COMMUNICATION
After a start up, the fi rst screen contains the main information about the CLIMATIC‘s software.
The DS is organised in 3 menus:
• (1000): alarms history,
• (2000): user menus for maintenance people,
• (3000): expert menus for agreed Lennox authorized Service company (restricted area with password).
To access to alarms history, press the “ALARM” key when you are in the main menu (0000). The CLIMATIC saves up to the last 32
alarms. An active alarm is signaled by the symbol “*” whereas an alarm inactive is symbolized by the “=”.
