Abstract:
The autonomous energy saving device (2) enabling the control of a water heater (1) connected to a power grid comprising a phase P, a neutral N and a protective conductor T operating on a permanent power supply or during rate periods using a switch or timer, said energy saving device (2) comprises inputs E1, E2, E3 and the outputs S1, S2, S3 and between inputs E1 and E2 and the outputs S1 and S2 at least one primary circuit board (7) comprising at least one electronic component (3, 4) and a control algorithm to remove or reduce the heating times of the water heater (1) without changing the technical characteristics of the water heater, and in order to adapt its operation to the needs of the user.
Abstract:
A thermal tripping device for fire protection installations in which an alarm, valve or other appliance is operated by release of a spring biased rod having at one end an eye normally held between two oppositely facing and overlapping hooked or nose shaped parts each formed on an end of two superimposed plate-like arms mounted at their other ends on a common pivot. Each arm has a concave part facing the other to define a free space which contains a bulb which explodes above a predetermined temperature to allow the arms to pivot open and release the rod, but while in an intact state the bulb holds the arms locked together.
