B&B Electronics DELTA Temperature Controller DTB Series - Manual (Page 4)

3
6 Operation
There are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets into the operation mode.
Press the
key to switch to regulation mode. If the key is pressed for more than 3 seconds, controller will switch to the initial setting
mode. Pressing the key while in the regulation mode or initial setting mode, forces the controller to return to the operation mode.
PV/SV: Sets the temperature set point and displays the temperature process value. Use keys to set the temperature set point.
Setting method: While in any function mode, press the key to select the desired function and use the keys to change settings.
Press key to save the changes.
The next flow chart shows how to switch for settings and internal functions:
