EnviraCom™ is a 3-wire communication protocol that allows controls to publish information relating to status, alarms, etc. on the network. This information differs by control, and includes flame signal strength or resistance, number of cycles, run time, alarm information, diagnostics information, etc. EnviraCOM offers peer to peer communication that makes networking a simple proposition.
