  • Boiler protection apparatus and method
    Patent number: 8008603
    Abstract: Apparatus and methods for protecting a boiler and heating system from damage comprising a control board having inputs and outputs, a processor having inputs and outputs, at least one ambient sensor in communication with the processor, at least one boiler sensor in communication with the processor, a power failure relay, the power failure relay being in communication with the processor wherein the power failure relay is capable of detecting power failure of the boiler, an alarm relay connected to the control board by the at least one output and which is capable of sending notification to an alarm system. When an ambient temperature detection event occurs the ambient sensor communicates with the processor and switches the control board from passive mode to monitoring mode.
