Methods and systems for determining tint of at least one tintable window when the outside temperature is greater than a first threshold and/or less than a second threshold value.

A drive device of an elevator includes a frequency converter to be connected to a public AC supply network and an elevator motor. The frequency converter includes a network rectifier configured to be connected to the AC supply network, a motor bridge to be connected to the elevator motor and a DC intermediate circuit located between the network rectifier and the motor bridge. The motor bridge is controlled by a control circuit which feeds the motor bridge with control pulses to regulate the motor speed. The drive device further includes at least one drive prevention circuit connected between the control circuit and the motor bridge. The drive prevention circuit is configured to obtain a safety signal from an elevator safety circuit includes two separate safety input circuits each configured to be connected to the elevator safety circuit to receive a safety signal. Each of the safety input circuits is configured to interrupt the connection between the control circuit and the motor bridge in response to the safety signal status.

A control panel is used to control and/or monitor an automation system. The control panel may be removed from a mounted location to repair or replace the control panel. Replacement may be performed by a different provider of automation systems, potentially without prior notice to the current provider of the automation system. To alert the provider of the replacement, the control panel may use an anti-tamper switch to detect removal from the mounted location. A signal may be sent to a remote service system indicating the removal. If the control panel also loses AC power, or if the control panel loses all power, the remote service system may assume that the control panel is being replaced. In response, the remote service center may request that a customer service representative contact the customer to potentially retain the customer, recover equipment, or resolve any concerns about the automation system equipment.

A method of controlling a gas furnace system includes controlling a motor of a draft inducer to increase a speed of the motor in response to a call for heat, receiving pressure signals output by a pressure transducer, receiving signals indicating whether a pressure switch is in a first state or a second state, and determining a first status of the pressure transducer as reliable, unreliable, or questionable at a first time based on the received pressure signals from the pressure transducer, the signals indicating whether the pressure switch is in the first state or the second state, and a first status of the motor of the draft inducer at the first time. Operation of the motor of the draft inducer is stopped when the first status of the pressure transducer indicates that the pressure transducer is unreliable.

In some embodiments, the system is directed to an autonomous inspection system for electrical grid components. In some embodiments, the system collects electrical grid component data using an autonomous drone and then transmits the inspection data to one or more computers. In some embodiments, the system includes artificial intelligence that analysis the data and identifies electrical grid components defects and provides a model highlighting the defects to a user. In some embodiments, the system enables a user to train the artificial intelligence by providing feedback for models where defects or components are not properly identified.
