7.4.11 Switching the cooling unit on and off in ME
(only with Control Center 3)
At the position which is furthest to the left of the temperature set point regulator is the switch to turn
the cooling unit on and off. Locking the switch in and then out again, switches the unit on. Feedback
is shown on the display. When AC blinks there, it means that the cooling unit has been contacted by
the Control Center. If AC is shown, but it's not blinking, then the cooling unit is switched on. To switch
the cooling unit off, lock the switch in and out once again. If no feedback is registered from the cooling
unit within the first 60 seconds, then the corresponding Control Center output will be deactivated. A
special error message will not appear.
When the motor is switched off, the cooling unit will be automatically out of operation.
