Operating status
The controller's operating status can be called forth by a brief (1s) activation of the
upper button. If a status code exists it will be shown. (Status codes have lower priority
than alarm codes. This means that status codes cannot be seen if there is an active
alarm code.
The individual status codes have the following meanings:
S10 (off ): Regulation stopped by the internal start/ stop.
S20: Emergency cooling is activated because of defect sensor
S42: Heat recovery or heat pump control is active
S43: Higher capacity through displacement of the pressure reference
