7.2 Function
“intermediate agitating” in cooling mode [P22]
The MRF-
M2 has a function that enables manual ‘intermediate agitating’ in cooling
mode during the agitator break. This can be done is different ways.
Regardless of the chosen option the corresponding LED always indicates when the
agitator is operating.
The function is defined in the ‘Cooling parameter 2’ level via the parameter [P22].
Parameter [P22] is set to 0:
“Intermediate stirring” is not possible.
Parameter [P22] is set to 1
(standard):
"Intermediate agitating SHORT or LONG" can be switched on via the regulator's foil
keyboard. In this case:
Briefly press the "AGITATOR" button in cooling mode:
"Sho" appears in the display. If the
button is released now, a ‘short intermediate
agitating’ is triggered. [Duration = c23]
If the “AGITATOR” key is held down for a longer period of time:
The display changes from "Sho" to "Lon". A "long intermediate agitating" is trig-
gered. [Duration = c24]
Parameter [P22] is set to 2:
Function: Continuous agitating ON / OFF
Press the ‘agitator’ key: the agitator is switched ON.
Press the ‘agitator’ key again: the agitator is switched OFF again.
7.3 Emergency cooling in the event of a sensor fault
In the event of a defective temperature sensor, the fault code appears on the display
only during cooling mode:
- F56 = Broken sensor
- F57 = Sensor short circuit
- F58 = Sensor range exceeded
Switch on emergency cooling:
Requirement:
- in parameter [P4] a timer must be set,
- one of the above error messages must flash on the display.
Press the COOLING button for at least 4 seconds:
Compressor and agitator are switched on for the time set [P4]
"not" appears in the display alternating with the remaining running time in minutes.
The timer can be ended prematurely at any time with the OFF button.
