VMB1TSW - Temperature sensor for use with vmb1tc(w), white

You can accurately monitor the temperature in any room where you install this sensor module. Use it to directly control the heater or in combination with our temperature controller VMB1TC (black version) / VMB1TCW (white version) which lets you group rooms and use weekly programs. It doesn't make a difference whether you use a centralized heating system or local heaters.

Compatible with Bticino® frames : Living®, Light® & Light-Tech®

Q. Using VMB1TS without the VMB1TC controller module
A. If you wish to set a weekly program for your VMB1TS sensors without using a VMB1TC controller, you can use push buttons and program steps on input modules instead (eg. on a VMBGPOD glass controller module).

Q. How does the "central heating" channel work?
A. The "central heating" channel is pressed when the sensor is in day or comfort mode.
