Menu survey

Function
The menus from either column 1 or column 2 are shown
Normal display
During regulation the actual level of superheating is displayed.
(If you would like to see the expansion valve's actual opening degree, press the bottom button for
approx. one second.)
During control with an analogue signal the opening degree is displayed.

Miscellaneous
Controller's address
If the valve's opening degree should be controlled with an external signal, the signal is defined as:
0: no signal
1: 0-20 mA
2: 4-20 mA
3: 0-10 V
4: 1-5 V
Manual control of outputs:
OFF: no manual control
1: Manual control with "o45" enabled
2: Simulate Alarm off : connection between 24 and 25
3: Simulate Alarm on : connection between 24 and 26
Working range for pressure transmitter – min. value
Working range for pressure transmitter – max. value

Manual control of the valve's opening degree. The function can only be operated if o18 has been set to
"1".
This function is only for manual operation. It must not be used for as a regulation function.
Selection of control mode:
1=Normal
2 = With inner loop (S media temperature less T0)
Application mode. Menus blanked out so only the shaded menus are seen. See the two columns to the
right.
1: Controlling a valve with an analogue signal
2: Superheat regulation
Service
Analog input (21-22)
Read status of input DI (20-21)
Temperature at S2 sensor
Superheat
Superheat reference
Read valve's opening degree
Read evaporating pressure
Read evaporating temperature
Temperature at S4 sensor
Configuration settings (n03, n37, n38, n39, n40, o03, o30, o56 and o61) available only when regulation is stopped (r12=off ).
Factory settings are indicated for standard unit (see code number, page 1). Other code number have customised settings.
