5.3.2 Display during operation
During operation, the display shows the system temperatures, maximum values, and calculated values. After showing the start
display, the Solaris R3 controller switches automatically to operation display mode, an operation value is displayed and the
relevant light is illuminated.
•
Pressing the arrow keys permits navigation between the four temperature values (see Table 5-2) and the flow rate value.
•
Pressing the Info key displays the maximum values and the calculated values (see Table 5-3).
The left-hand column of the display shows the following status information :
– "1" in the first line, circulation pump P1 running.
– "2" in the 2nd line, output for booster pump P2 active.
– "B" in the 3rd line, burner inhibit contact active (see Section 5.3.8) or an error status (see Chap. 6.2).
– "H" in the 4th line, manual operation active.
5.3.3 Setup menu
The parameters of the Solaris R3 control unit are displayed and can be changed in this menu.
•
Pressing the OK key once (>2 s) either activates the menu or returns to the operating display. Briefly pressing the key
confirms a choice, opens the next menu item, or displays “Saved” for about 1 second after a value has been changed.
•
In the selected parameter display, pressing the OK key switches over to the parameter changing mode.
The first line of the menu (Image 5-5) shows the active menu item, whilst in the left-hand column a cursor (">") points to the
next lower menu item or to a parameter. From here, you navigate to the respective menu tree by means of the arrow keys: up
(+ key) or down (– key). The adjusted value can be changed accordingly with the arrow keys. Briefly pressing an arrow key
changes the value by one step, and continuous pressing speeds up the change. After changing the required parameter, and moving
down through the entire parameter list, then display returns to the choice menu "Choice 2/2", and from there to the operating
display (see Image 5-5). The control unit starts working with the changed parameter value(s) immediately. The display always
returns to the operating display mode after 10 minutes, provided that no key is pressed during this time.
The measurement or info display that has been accessed remains active as long as no manual adjustments are
made or no event according to Table 6 -2 calls up a different form of display. It is also reactivated after param-
eter changes or switching off and on. If info parameters are displayed, no measuring point indicator lights are
activated.
