The Delta™ Room Controller is a Native BACnet™ Application Controller that communicates             LCD
on an RS-485 LAN using the BACnet™ MS/TP protocol.
                                                                                                    Large font 4-digit alpha numeric
The controller is housed within a stylized wall mounted housing and includes programmable           display (for time or objects values)
LCD and keypad functions, and supports the Delta BACstat™.                                          Small font 4-digit alpha numeric
                                                                                                     display (for time or units display)
Strategies are written in GCL, rather than reside in fixed algorithms.
                                                                                                    12-digit alpha numeric display
