Description
Caleffi manual reset minimum pressure switch is a device for interrupting the electrical operation of the heat generator, in this case with a graduated scale (bar) from 0.5 to 1.7.
N.B. This device is not able to prevent pressure increases that may occur even after the pressure switch has been activated. For this reason, it is essential to install other safety devices, as required by regulations, which ensure pressure control below the maximum permitted limit of 5 bar (for example, a safety valve) and maintenance of the fluid temperature below 110°C (for example, via a thermostat).
