Operational settings of the refrigeration controller TAR 1309 (standard)
Changes to the settings of the refrigeration controller should only be performed by a
refrigeration specialist.
Depending on the unit type - normal cooling (GEKN) or deep-freezing (GEKT) -, the
controller is set with the parameter described below. Should you need to adjust these
settings, please observe the specified permitted operation parameters P05 and P06 for room
temperatures. Non-observance will lead to the loss of any warranty claims for the
refrigeration unit.

1) It is important to ensure that the evaporator does not ice up during operation.
The defrost times are to be set according to need and the corresponding requirements.
2)
Entry of the alarm temperature in °C. This does not automatically adjust to the set-point for room temperature (P03).
