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. When a temperature detection event or a heating system malfunction occurs the boiler sensor or power failure relay or other types of sensors communicate with the processor and initiate an alarm pathway or provide a circulation mode for circulating water through a heating system of an enclosure to be heated by the boiler and heating system. The control board may provide for the boiler to return to normal function when the temperature detection event or the heating system malfunction ends. The apparatus may also be used to prevent boiler, heating system and enclosure damage by initiating other actions when a heating system malfunction occurs.
