MC3-SC Stepped Controller
Document no.: 140744 version 1.3
Page 10 of 45
2.5.2 Login symbol
This lets you see whether the user is logged in and able to make changes, can switch the controller to
standby or off, etc.
2.5.3 Standby button
This button can be used for switching the controller to standby and then turning it off if desired.
2.5.4 Control data for regulating the compressors
The control data is split into three layers: a pressure component, a calculated temperature
component and a measured temperature component (which requires a suction-side temperature
sensor).
The measured values are always shown in the middle, with the setpoints on the right. These
setpoints are shown in blue. If the defined setpoint is overruled by an external setpoint, the defined
setpoint is shown in a small font with the active setpoint below in a larger font (and in black).
2.5.5 Control data for regulating the condensers
Like the compressor regulation, the control data is split into 3 layers. As an exception, the lowest
layer does allow the measured discharge temperature, the measured outside temperature or both
to be displayed. This depends on the parameters and whether one or both sensors are connected.
