Abstract: There is described a system and method of a building management system for preventive maintenance of an HVAC unit. Runtime data of the HVAC unit is received at a control system remote from the HVAC unit. A service message is initiated, by the control system, to a service device associated with the HVAC unit in response to determining that a preventive maintenance visit is warranted based on the runtime data. A hot-cold test for the HVAC unit is activated by the control system in response to receiving the registration message of the preventive maintenance visit from the service device. A validation message is reported in response to validating the preventive maintenance visit based on a result of the hot-cold test for the HVAC unit.

Abstract: There is described a support system and method for automated building management assistance. Fault detection and diagnostics relating to a maintenance event for building equipment is collected from a building automation system in response to receiving a message identifying the maintenance event from a mobile device. Manual tasks are provided to the mobile device to address the maintenance event in response to identifying the status as a basic issue. The manual tasks include manual actions to be executed at the equipment at the particular building based on interactions between the automated support system and the mobile device. Semi-automated tasks are provided to the mobile device to address the maintenance event in response to identifying the status as an advanced issue. The semi-automated tasks include one or more manual tasks and one or more automated tasks determined by the automated support system for execution by the building automation system.

Abstract: Automation systems, methods, and mediums. A method includes identifying a first amount of energy consumed by a plurality of devices in a building during a first period of time while a first device in the plurality of devices is in a first state to form a first baseline. The method includes identifying a second amount of energy consumed by the plurality of devices during a second period of time while the first device is in a second state. Additionally, the method includes generating an estimated energy consumption of the first device based on a difference between the first baseline and the second amount of energy consumed.

Abstract: Building automation systems, energy meters, and associated methods. A method includes receiving a plurality of voltage inputs and a plurality of current inputs from a multiphase power source. The method includes selecting a first voltage input from the plurality of voltage inputs. The method includes performing a signed power factor computation between respective pairs of the first voltage input and each of the plurality of current inputs. The method includes identifying a pair with a greatest positive power factor value. The method includes designating the identified pair with the greatest positive power factor value as an associated phase pair.

Abstract: Systems, methods, and mediums perform automated functionality testing for a heating ventilation and air conditioning (HVAC) system. A method includes receiving a user input to test one of a heating or cooling functionality of the HVAC system. The method also includes identifying an amount to change a setpoint for a zone controller for the HVAC system based on the user input. The method further includes changing the setpoint for the zone controller to force the HVAC system into one of a heating mode and a cooling mode in accordance with the user input. Additionally, the method includes storing data from the HVAC system operating in the one of the heating mode and the cooling mode.
