A zone command is sent to a temperature control system of the facility in which the zone command includes the start time of the zone temperature action for the first zone.

Abstract: A circuit breaker for active detection of an arc fault comprises a controller and an actuator. The controller monitors a load current of one or more devices connected to the circuit breaker. The controller detects an arc-like signal in the load current and decreases power temporarily to the connected device(s) for a temporary period of time in response to detecting the arc-like signal in the load current. The controller determines whether the arc-like signal is present in the load current while the power is decreased. The actuator inactivates the load current in response to the controller determining that the arc-like signal is not present in the load current while the power is decreased.

Abstract: An overload protection system compromises a panelboard and a LMS which is configured to constantly measure the total amount of power being used at the panelboard such that when the total amount of energy measured is at or above a high programmed level, the LMS stops power from being supplied to a load and when the total amount of energy measured is at or below a low programmed level, the LMS allows power to be supplied to the load. The LMS comprises a monitoring relay with a “threshold hysteresis” built-in, which means that a threshold current at which an output switches from one state to another state is different depending on whether an input current is increasing or decreasing. The “threshold hysteresis” helps to eliminate noise and ensure that the output switches cleanly between ON and OFF, even if an input current level is fluctuating around a threshold current level.

A dynamic nominal is determined based on the operation measured flow and a particular calibration relative flow corresponding to the operation position of the flow control element. The operation position of the flow control element is controlled based on the operation measured flow and the dynamic nominal.
