Electronic programmable thermostatic actuator for installation on thermostatic and thermostatable radiator valves to regulate the ambient temperature.
The instrument acts on the valve itself, partialising the opening based on the difference between the set temperature and the measured one.
The function keys, roller, and LCD display allow direct programming on the instrument.
To further facilitate the operation, the mini programming USB can be used, allowing graphical programming directly on one’s own PC via the software.
