Auto-start Activation

The auto-start function is an automated routine to start the unit and subsequently equalize the CO
system. After starting, the system controller regulates the defined temperature setpoint. Simultaneously, the humi-
dity is built up. Once temperature and humidity have reached a constant value, the CO
automatically equalized to these values and CO
reached.
NOTE – Using the routine:
In order for the specified accuracy of the CO
always be used to start the unit if the adjustment of the temperature setpoint involves a change of more than 1 °C
or if the unit is being restarted after having been shut down for a longer period of time. In any case, the auto-start
routine should be run at least quarterly as part of normal cleaning and maintenance work.
As a rule, the routine requires 5 to 7 hours. Where the ambient temperature is low or the unit is cold, the routine
may take up to 10 hours. If the glass door is opened while the routine is running or if the unit is separated from the
mains power, the routine is interrupted. It will restart once either the door is closed or the mains power supply is
reestablished.
