Chapter 6 Display and encoder
All setting and configuration is done using the display and encoder.
The menu information on the display is organised in a tree fashion. Using the encoder you
can move between menus, set values etc.
In any of the configuration menus, a press on the encoder will activate change mode. You
can then rotate the encoder button to move between choices or set values. A second pressing
of the button will accept the choice.
The menu system is divided into two levels: The Basic level and the 10-second level which
contains all the configuration menus.
The Basic level
The Basic level comprises three sets of menu displays, the Base Display, the I/O Displays
and the Setpoint Display.
Base Display
This is an example of the Base Display, the display that is normally shown when there is no
operator activity.
The upper line shows which control mode has been configured, in this case control mode 1,
Temperature control. The bottom line shows the actual value of the main input parameter.
There are bar-graphs showing the current output levels. In control mode 1 there are symbols
showing how the outputs have been configured (Heating, Cooling, Damper or Change-over).
I/O
When the Base Display is shown, by twisting the knob counter clockwise until the text I/O is
displayed and then klicking on it, you can gain access to a menu where you can look at the
values and states of all inputs and outputs.
To exit this menu again, klick on the knob and then twist the knob clockwise and you will be
returned to the Base display.
Setpoint
When in the Base Display, a press on the encoder button gives direct access to the Setpoint
menu.
See chapter 7 Setpoint.
