Temperature sensor Sensor type for S3, S4 and S5. Normally a Pt 1000 sen-
type sor with great signal accuracy is used. But you can al-
so use a sensor with another signal accuracy. That
could e.g. be a PTC sensor (1000 ohm at 25 °C). All the
mounted sensors S3-S5 must be of the same type.
Sensor point 1 - The temperature value for the user-defined tempera-
Temp. ture sensor in the reference point.
Sensor point 1 - The resistance value in kohm for the user-defined
kohm temperature sensor in the reference point.
Sensor point 1 - The resistance value in ohm for the user-defined tem-
ohm perature sensor in the reference point.
Sensor point 2 - The temperature value for the user-defined tempera-
Temp. ture sensor in the reference point.
Sensor point 2 - The resistance value in kohm for the user-defined
kohm temperature sensor in the reference point.
Sensor point 2 - The resistance value in ohm for the user-defined tem-
ohm perature sensor in the reference point.
Sensor point 3 - The temperature value for the user-defined tempera-
Temp. ture sensor in the reference point.
Sensor point 3 - The resistance value in kohm for the user-defined
kohm temperature sensor in the reference point.
Sensor point 3 - The resistance value in ohm for the user-defined tem-
ohm perature sensor in the reference point.
Defrost method Select method of defrost
Defrost stop meth- Here you define whether a defrost cycle is to be stop-
od ped by time or by a temperature sensor
Defrost stop limit A When the selected defrost stop sensor reaches the set
limit, the defrost cycle is terminated
Food type When changing the food type the controller will auto-
matically adapt temperature setpoints and alarm lim-
its according to the selected food type. Please be
aware that the setting will revert to "None" after hav-
ing been changed.
Food temp. sensor Select the temperature to be used for the food tem-
perature representation
Network address Network address of the controller
