• Select only one function per input, e.g. condenser sensor or ambient light sensor.
• Make sure that the accessory you select has a matching connector to the input, e.g. a sensor for input "S2" must have "S2" connector.
• Condenser sensor or light sensor are optional and can be omitted.
• Defrost sensor is mandatory when electrical heater is used for defrost. For natural defrost it can be omitted.
