External NTC Temperature Probe, Four-Piece Pack (TS01B04ACC) is an Eelectron product for KNX-based building automation. TS01B04ACC is listed in Eelectron’s technical catalogue as an external temperature probe supplied in a four-piece pack. It is an accessory intended for use with compatible Eelectron devices that provide analogue NTC probe inputs. External sensing allows temperature to be measured at a location separated from the controller or room interface, subject to the cable and sensor specifications of the receiving device. The probe is a passive sensor accessory rather than a KNX bus-powered field device, so it does not have its own KNX physical address, bus-current consumption or ETS application.

The TC28A01KNX documentation separately identifies an NTC probe code TS01B01ACC with a specified range of −50 °C to +60 °C; that code is not identical to the four-piece catalogue code TS01B04ACC. For that reason, this record does not transfer the TS01B01ACC range to TS01B04ACC. Confirm the sensor curve and supported temperature range with Eelectron for the exact pack code before using it in a project. Cable length, lead construction, probe dimensions and ingress protection are not specified in the available catalogue extract and are intentionally left blank.
