What is Swarm Logic? Traditional Method Swarm Logic Method Auto DR Event

Swarm Energy Management Easily Deployed using Your Existing HVAC Service Team, without IT Modifications A ZigBee network allows Controllers to “talk to each other” in a swarm. A Gateway provides Internet communication without the need to access the site’s network. Power readings and decisions are uploaded every 5 minutes. Swarm Energy Cloud HVAC Swarm Energy Management Web 2.0 APIs HVAC Controllers are monitored and adjusted via a web based portal. LIGHTING HVAC PUMPS Controllers measure power readings every 30 seconds. Each Controller makes a decision every 10 minutes. ELECTRIC HEATING Customer Portal
