BF451, digital thermostat.

BF451 is a digital wall thermostat equipped with alphanumeric backlit display with two lines to facilitate the displaying of all the settings and simplify programming. The device is equipped with double hysteresis and can be used for heating or cooling control (for the control of both we recommend the BF454 model). The maximum and minimum temperatures are registered by the last turning-on or by the last deletion.

The message displayed on the first line can be personalised by the user, a useful function if more devices are installed.
