Abstract

See full text

The present disclosure includes an HVAC system that includes a plurality of dampers each corresponding to one building zone of a plurality of building zones, a plurality of sensors each corresponding to the one of the plurality of building zones, and a control board communicatively coupled with the plurality of dampers and sensors. The control board includes a plurality of status light sources, each corresponding to one damper the plurality of dampers, a plurality of communication light sources each corresponding to one sensor of the plurality of sensors, and a microcontroller programmed to control operation of equipment in the HVAC system. The microcontroller is configured to perform “a hardware test mode” to facilitate diagnosis of the plurality of dampers by causing the plurality of status light sources to sequentially execute a first light scheme or a second light scheme in response to instructions to the plurality of dampers.
