Safety device for a gas apparatus for heating and for producing hot water with controlled mechanical ventilation.

摘要

The invention relates to a safety device for a gas boiler. The device makes it possible to stop the apparatus in the event of an operational anomaly in the mechanical ventilation controlled by virtue of a temperature sensor 19 whose reference values are slaved to the power values of the boiler 5. A microprocessor 18 has, in memory, the reference-temperature information of the sensor and gives rise to using the safety device as a function of the signals received. Application to apparatuses with controlled mechanical ventilation. <IMAGE>
