ALARMS MENU: DISPLAY OF THE ALARM STATUS
Signaling an alarm: external air temperature probe
Alarms menu
If an alarm is being signaled, you can reach the specific menu directly by touching the screen. Otherwise you must select the Alarms
item in the menu selection page and press OK. If the control is interlocked to several units (master/slave mode), you must select the
unit you want to monitor (see Status menu), otherwise you direct access to the detail alarms page.
If the control detects an abnormal status, the latter is indicated in the main control screen by a specific flashing icon and a red writing
at the top of the screen (Call service o DirtyFilters). If the alarm is detected when the screen is in stand-by mode, the display flashes at
about 10-second intervals. Alarms on pressure sensors are available for machines with cop/cav kits only.
