BX-TE is the innovative push-button interface equipped with an external temperature probe to perform thermostat functions.

This is a digital temperature sensor with a thermostat function, complete with a 4-input KNX push-button interface that converts a traditional push-button panel into a KNX source. Regarding the push button interface functions it has all the features of the BX-4XIO model, moreover, it adds the necessary features to control the thermostat.
The device is developed without a display unit or local buttons, therefore, setpoint temperature adjustment and visualization can be exclusively carried out via a Blumotix supervision system like a touch panel or a common smartphone on which is installed the dedicated application.
The BX-TE is equipped with a highly sophisticated digital solid state temperature probe, able to carry out accurate measurements, from -55 °C to 125 °C with 0.5 °C of resolution, and not requiring any calibration procedure.
The temperature probe is extremely compact and can be fitted to the rear of the hole plugs of standard devices suitable for measuring towards the inside of a room.
