The controller is configured to initiate a call for heat when the measured temperature reaches a trigger temperature, wherein the trigger temperature is a differential amount less than a set-point temperature, calculate a reduced activation time when the call for heat results in a predetermined number of calls for heat occurring within a predetermined time period, and control the burner based on the reduced activation time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for controlling water heaters","description":"A water heater includes a storage tank, a sensor configured to measure a temperature of water in the storage tank, a burner configured to heat the water in the storage tank, and a controller communica","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9829897","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
