Heat pump controller

A water heater control system comprising an energy storage system electrically connected to a pilot valve operator and electrically isolated from a main valve operator. The energy storage system may be electrically connected to an ignition circuit. A thermoelectric device is in thermal communication with the pilot flame and electrically connected to a main valve operator. The water heater system may include a microcontroller configured to establish electrical communications between the device and the energy storage system, the pilot valve operator, and the main valve operator. The microcontroller may be configured to recognize a call for main burner operation, and may also be configured to check an available voltage of the energy storage system against a setpoint. The microcontroller may establish pilot flame operation with or without main burner operation, depending on whether a call for heat or recharging of the energy storage system is required.

Control system for an intermittent pilot water heater

A locally powered intermittent pilot combustion controller may include an igniter, a thermal electric and/or photoelectric device that produces an electrical signal having power when exposed to a flame, and a local power source for providing power when the thermal electric and/or photoelectric device is not exposed to a flame. In some cases, the intermittent pilot combustion controller may include a memory for storing information about an ignition sequence for igniting a pilot flame, and a controller coupled to the memory. The controller may be configured to initiate the ignition sequence of the pilot flame using information stored in the memory, determine whether the ignition was successful by monitoring the electrical signal produced by the thermal electric and/or photoelectric device, and adjust the information stored in the memory based on whether the ignition sequence completed successfully.

Method and system for controlling an ignition sequence for an intermittent flame-powered pilot combustion system

A water heater control system the water heater system comprising a rechargeable and non-rechargeable power source. In one or more examples, a controller such as a microcontroller of the water heater system is configured to receive power from the non-rechargeable power source and does not receive power from the rechargeable power source. Various other components of the water heater system are configured to receive power from the rechargeable power source. The system may comprise an energy storage system electrically connected to a pilot valve operator and electrically isolated from a main valve operator. The controller may be configured to recognize a call for main burner operation and may also be configured to check an available voltage of the energy storage system against a setpoint.

Burner control system

A heat balancing system for a natural draft gas burning appliance having a flue. When the appliance is in a standby mode, a main burner is shut off and the pilot light remains on. Temperature in the heat exchanger (e.g., temperature of water in a heater tank) may be decreased or increased, respectively, by opening or closing a damper in a flue as needed. If opening the damper does not sufficiently reduce the temperature of the heat exchanger, then the pilot light may be shut off to further reduce the temperature. The pilot light may be turned on again to bring up the temperature. There may be a control or controller to operate the damper to maintain the temperature of the exchanger within a certain range. Electrical power may be provided for the system from a power line, a storage device, or other source.

Heat balancing system

A flame powered intermittent pilot combustion controller may include a first power source and a second power source separate from the first power source, a thermal electric and/or photoelectric device, an igniter and a controller. The thermal electric and/or photoelectric device may charge the first power source when exposed to a flame. The controller and the igniter may receive power from the first power source when the first power source has sufficient available power, and may receive power from the second power source when the first power source does not have sufficient available power.

Method and system for starting an intermittent flame-powered pilot combustion system

An illustrative HVAC controller may include a communication module for wirelessly communicating with a network and wiring terminals for receiving a wired connection to a remote temperature sensor that is situated remote from the HVAC controller and in a living space of the building. A controller may be operably coupled to the communication module and the wiring terminals and may be configured to implement a thermostat control algorithm to generate one or more control signals, wherein the one or more control signals are provided by a wired connection to the HVAC system to control one or more HVAC components of the HVAC system. The thermostat control algorithm may be configured to compare a sensed temperature received from the remote temperature sensor via the wiring terminals and a temperature setpoint received from the server via the network.

HVAC control with a remote user interface and a remote temperature sensor

A remote water heater monitoring system is configured to communicate with a plurality of client water heaters over a network. The system processes received data related to the operation of the plurality of client water heaters and identifies one or more baseline trends over time related to water heater performance and/or water heater reliability using the received data from one or more of the client water heaters and identifies one or more abnormalities in the operation of a particular one of the client water heaters based on the baseline trends. An alert is generated for one or more of the abnormalities in the operation of the particular one of the client water heaters and is associated with a corresponding client account.

Cloud-based analytics for water heaters

A furnace controller for a modulating furnace that helps provide a balance between energy efficiency and occupant comfort across various burner firing rates and/or across various circulating blower speeds. In some cases, the furnace controller can be configured to permit a user to customize operation of the furnace in accordance with their particular needs and/or desires with respect to efficiency and comfort. A selection may be made between an energy efficiency setting and a user comfort setting. Then, a plenum parameter such as a discharge air temperature (DAT) or discharge air flow (DAF) may be regulated in accordance with the selected setting.
