摘要： A furnace system of a heating, ventilation, and/or air conditioning (HVAC) system includes a burner assembly having a burner enclosure configured to receive a fuel for ignition to generate heated combustion byproducts. The furnace system also includes a controller configured to detect a value associated with a wave signal transmitted through the burner enclosure and operate the furnace system based on a comparison between the value and a threshold value.

摘要： A controller for use in a gas appliance system includes a circuit board, a plurality of connectors and a processor mounted on the circuit board. The processor controls operation of the gas appliance using, in part, at least one connector of the plurality of connectors and control settings for an intermittent pilot (IP) system in response to a user selection to configure the controller to control an IP system, and controls operation of the gas appliance using, in part, at least one connector of the plurality of connectors and control settings for a direct spark ignition (DSI) system in response to a user selection to configure the controller to control a DSI system.

摘要： A method for controlling a gas furnace including measuring an indoor temperature, comparing the indoor temperature with a set temperature for heating, and operating the gas furnace in weak heating with a predetermined heating capacity, which is lower than a maximum heating capacity of the gas furnace, when the set temperature for heating is higher than the indoor temperature by a temperature value, which is less than a predetermined temperature value. The predetermined heating capacity for weak heating is maintained at a current heating capacity for weak heating, when the gas furnace operates in weak heating, and when an operating duration with the current heating capacity for weak heating is less than a first time value.

摘要： A heating, ventilation, and/or air conditioning (HVAC) system includes a control system configured to initiate an operating cycle of a furnace of the HVAC system at an initial operating stage in response to a call for heating, monitor a duration of time associated with the operating cycle of the furnace to satisfy the call for heating, adjust the initial operating stage to provide an adjusted initial operating stage of the furnace based on the duration of time, and initiate a subsequent operating cycle of the furnace at the adjusted initial operating stage.

摘要： A system includes a modulating furnace and control circuitry. The control circuitry is configured to receive a call for heating associated with a quick heat cycle. In response to the call for heating, the control circuitry is also configured to operate the modulating furnace in a quick heat operating mode for a threshold time period. Subsequent to the threshold time period, the control circuitry is also configured to operate the modulating furnace in a modulating heat operating mode.

摘要： Disclosed are systems and methods for automated furnace inducer sensor output verification. A furnace may include a sensor, such as a transducer, that may be used to measure pressure within the furnace (for example, pressure resulting from the operation of a draft inducer blower and/or any other component of the furnace). It is possible that the data produced by the sensor may remain relatively fixed for a given period of time. However, this makes it difficult to determine if the data is valid or if the sensor is malfunctioning. Given this, an algorithm is used to change a motor speed of the inducer blower. The subsequent data that is produced by the sensor is then monitored to determine if an expected change in the data occurs. If the change does not occur, then it may be determined that the sensor is malfunctioning.

摘要： A portable heater includes a housing enclosing a combustion region, a first connector for connecting with a fuel source, a first supply line in fluid connection with the first connector for supplying fuel to the combustion region when the fuel source is connected with the first connector, a second supply line in fluid connection with a second connector for supplying fuel to a fuel-fired accessory when the fuel source is connected with the first connector and the fuel-fired accessory is connected with the second connector, and a valve arrangement operable to selectively supply fuel to the first and second supply lines when the fuel source is connected with the first connector.
