These displays appear only if the controller option is enabled.
The loop display modes are interactive, in that the setpoint, the Auto/Manual mode and the Manual
Output value can be edited from the user interface. Full configuration is carried out in the Loop setup
menus and a fuller description of control loops is to be found as
Appendix B to this manual.
Figure 1.4.7 depicts a single loop display and the dual loop display. The up and down arrow keys are used
as normal to scroll through Loop1, Loop2 and Dual loop pages.
