Grand Meyer® MST-10

A simple and reliable electronic temperature controller for underfloor heating control is used in cases where programming is not required. It has a separate power switch and LED indication of underfloor heating operation. It is completed with a temperature sensor (NTC, 10 kOhm), which is installed in the floor between the coils of the heating cable. The length of the sensor wire is 3m. The temperature controller controls the load up to 16A. Available in two colors: white and ivory. The temperature controller is designed for hidden (recessed) mounting in the socket of the mounting box.
