NTC Temperature Probe (TS01A01ACC) is an Eelectron product for KNX-based building automation. TS01A01ACC is an Eelectron NTC temperature probe accessory identified by the TC28A01KNX technical documentation as a supported sensor for its configurable analogue inputs. It is intended to provide a remote temperature measurement where the controller is configured for NTC probe operation rather than dry-contact input. The manufacturer specifies a measurement range of −20 °C to +100 °C for this probe code. It is a passive sensor accessory and does not operate as a standalone KNX bus device; it must be connected to a compatible Eelectron input configured for the matching NTC characteristic.

For the TC28A01KNX, the manufacturer specifies a maximum connecting-cable length of 30 m using twisted cable for NTC probe inputs. Correct sensor selection and ETS configuration are important because Eelectron lists multiple probe variants with different temperature ranges. Do not substitute another probe code solely because its connector appears similar. The probe itself has no KNX medium, KNX bus-current consumption, relay outputs or independent ETS application. The product code is retained as supplied in the model list; pack quantity, physical dimensions, lead length and ingress-protection rating are not published in the controller datasheet and are therefore left unspecified here.
