The controller of the Danfoss Ally thermostat does not work in binary mode, but recognises intermediate stages. Here are some important details:

- The thermostat uses PID (Proportional-Integral-Derivative) control, which allows for precise temperature control.
- The actuator of the thermostat is electromechanical and moves the spindle linearly, up to 4.5 mm, with a maximum movement of 2 mm on the valve (1 mm/s).
- This allows fine adjustment of the valve opening to achieve the desired room temperature, rather than just switching between fully open or closed.
