Abstract
In exemplary embodiments, HVAC communication bus decoders and corresponding methods are disclosed. In an exemplary embodiment, an HVAC communication bus decoder includes a control circuit having an input for coupling to an HVAC communication bus and one or more relays each having an output for coupling to a legacy HVAC system monitoring device. The control circuit is configured to read one or more messages transmitted on the HVAC communication bus, decode the one or more messages to determine a desired mode of operation called for by a thermostat connected to the HVAC communication bus, and energize at least one of the one or more relays to emulate a corresponding legacy HVAC signal representing the mode of operation called for by the thermostat to be provided to the legacy HVAC monitoring device.
