Danfoss AK-CH 650 User Manual

100 Capacity controller RS8ER302 © Danfoss 2016-02 AK-CH 650
Display of brine temperature and condensing pressure
One to four separate displays can be connected to the controller.
Connection is accomplished by means of wires with plug con-
nections. The display may be placed in a control box front, for
example.
When a display is connected, it will show the value for what is indi-
cated in the conguration:
fx.
- compressors regulation sensor
- P0
- P0 bar (abs)
- S3
- S4
- Ss
- Sd
- Condensors regulation sensor
- Pc
- Pc bar (abs)
- S7
When a display with control buttons is chosen, a simple operation
via a menu system can be performed in addition to the display of
brine temperature and condensing pressure.
