Self-sustaining control for a heating system
View Patent ↗A self-sustaining control for a heating system, having conventional operational modes and pilot burner assembly, is disclosed. A controller directs operation in accordance with a need-based protocol and monitors the condition of a storage device, which provides system power during the stand-by or off mode under normal conditions. A thermo-electric device is in thermal communication with the pilot burner assembly and powers the system whenever the pilot is lit. Regardless of heat need, the controller directs operation in a pilot-on mode, in lieu of an off mode, whenever the storage device is compromised.
1. A control for a heating system, operable in an OFF mode, an ON mode and a PILOT-ON mode and including a pilot burner assembly, comprising, in combination:
a controller implementing a predetermined need-based protocol, said controller directing said OFF mode in the absence of a heating demand, said controller sequencing said heating system through said PILOT-ON mode and said ON mode in response to a heating demand;
a storage device having at least a first status parameter; and
a thermo-electric assembly in thermal communication with said pilot burner assembly; and
said controller being coupled to said pilot burner assembly, said storage device and said thermo-electric assembly;
said controller interconnecting said pilot burner assembly and said storage device to initiate said PILOT-ON mode, said storage device powering said pilot burner assembly to terminate said OFF mode, said thermo-electric assembly providing a potential to power said heating system and said controller during said PILOT-ON mode and said ON mode;
said controller storing at least a first status threshold related to said storage device and periodically receiving said first status parameter, said controller maintaining said PILOT-ON mode in lieu of said OFF mode whenever said first status parameter and said first status threshold have a predetermined relationship.
2. A control as claimed in claim 1 wherein said controller isolates said storage device during said PILOT-ON mode and said ON mode.
3. A control as claimed in claim 2 further comprising a display, operatively coupled to said controller, for indicating whenever said predetermined relationship exists.
4. A control as claimed in claim 1 wherein said controller interconnects said storage device and said thermo-electric assembly whenever said predetermined relationship exists, said potential recharging said storage device.
5. A control as claimed in claim 4 further comprising a display, operatively coupled to said controller, for indicating whenever said predetermined relationship exists.
