The controller then displays its current version for 2 seconds. LCD Backlight Pressing any key illuminates the LCD for 4 seconds. Night Set Back (NSB) Mode This function is only available if you have set input to nsb (Night Set Back contact). If the contact is triggered, the controller enters NSB Mode (the symbol appears) and uses the NSB setpoints defined at Steps, "NSB Heating Setpnt", "NSB Cooling Setpnt" and "NSB Fan Mode". Press any key to override NSB for the delay defined at Step, NSB Override Delay Minutes. The symbol flashes to indicate that the NSB mode is overridden (during this time the standard setpoints are used). No Occupancy Mode This function is only available if you have set input to OCC (occupancy contact). If the contact is triggered and the minimum occupancy time defined at Step 103, "OCC Minimum Time In Minutes" has elapsed, the controller enters Occupancy Mode (the symbol appears) and uses the OCC setpoints defined at Steps 107, "No OCC Heating Setpnt", 108 "No OCC Cooling Setpnt" and 105, "No OCC Fan Mode". Press the star * button to override no occupancy. Each time you press the star * button, 15 minutes are added to the override up to a maximum defined by Step 104, "No OCC Override Delay Minutes". Press the star * button until 0 is displayed to disable the override. The icon will flash and the remaining override time will be displayed in minutes. www.neptronic.com Page 24
