The MMC controller allows the connection of an external DS18B20 sensor. The external sensor is connected
to the contacts marked as R, B, Y. Contact R is power supply, contact B is GND and Y is contact for signal. In
the advanced setting, under the symbol 7 (SEN), set the value 1, to switch to temperature measurement using
an external sensor. If you want to measure again with the internal sensor, change the value back to 0.
When the device is off, the thermostat automatically turns on the device when the room temperature drops
below 5 °C. If the temperature rises above 7 °C, the thermostat automatically switches the unit off. This
function can be deactivated in the advanced setting, under symbol 6 (LTP), by changing the set value to 0.
In advanced settings, it is possible to calibrate the temperature, below the symbol 1 (ADJ). The values can be
adjusted in the range from -5 d 5 °C.
