Publication number: 20200018492Abstract: A temperature control system and a method of controlling air conditioning in a multi-zone structure are disclosed. The temperature control system includes a forced-air primary conditioning unit including an air return duct, an air supply duct, and a circulator. The temperature control system also includes a secondary combustion heat source that operates independently of the forced-air primary conditioning unit, a smart circulator thermostat, and a remote temperature sensor. The at least one memory device includes executable instructions that when executed by the at least one processor cause the processor to receive a temperature value representative of a temperature of the structure, receive an indication of an operation of the secondary combustion heat source, generate a circulator operation signal based on a comparison of the received temperature value to a selectable temperature setpoint, and the received indication of an operation of an independent secondary combustion heat source.Type: ApplicationFiled: July 10, 2018Publication date: January 16, 2020Inventors: David L.

Patent number: 10025328Abstract: Disclosed are exemplary embodiments of apparatus, systems and methods for power stealing for a wireless-enabled thermostat. In an exemplary embodiment, a wireless-enabled thermostat generally includes a control having a wireless network interface that intermittently connects the thermostat in a wireless network in accordance with a duty cycle, the duty cycle having a connect time in which the thermostat is connected in the wireless network and a sleep time in which the thermostat is not connected in the wireless network. A power stealing circuit of the thermostat steals power through an “on-mode” load of a climate control system to charge a capacitor or other energy storage device to provide the power for the wireless network interface. The control adjusts at least the sleep time in accordance with a time for charging the capacitor or other energy storage device to a threshold voltage.Type: GrantFiled: July 26, 2016Date of Patent: July 17, 2018Assignee: Emerson Electric Co.Inventors: Bradley C.

Patent number: 8275484Abstract: A controller for a variable heating system is operable to control a stepper motor operated gas valve to adjust gas flow to vary the heating level. The controller includes a first terminal for receiving a thermostat signal requesting heating, an electronic memory, and a microprocessor in communication with the electronic memory and first terminal. The microprocessor detects a thermostat signal requesting heating, and generates a control signal for the stepper motor to operate the gas valve. The microprocessor includes a programmable read-only-memory encoded with an instruction to store a time duration during which the microprocessor detects a thermostat signal requesting heating, and further encoded with an instruction operable to determine a predetermined heating level based on the stored time duration. The microprocessor responds to a thermostat signal requesting heating by determining the number of steps the motor must move to vary the gas flow corresponding to the predetermined heating level.Type: GrantFiled: March 23, 2010Date of Patent: September 25, 2012Assignee: Emerson Electric Co.Inventors: Thomas B.

Patent number: 7731096Abstract: A controller for a two-stage heat source is provide, which may be connected to either a single stage or a two-stage thermostat to provide low stage heating for a variable time period before switching to high stage heating. The controller includes at least a first terminal for receiving a signal requesting heating from a single-stage thermostat or a two-stage thermostat connected to the first terminal. A microcontroller in communication with the first terminal determines a duty cycle value for a heating cycle based on the duration in which a signal at the first terminal is present relative to the duration of the heating cycle. The microcontroller determines a low stage time limit from the duty cycle, and provides low stage heating when a signal is present at the first terminal for a time period not more than the time limit, and switches to high stage heating after the time limit.Type: GrantFiled: November 2, 2005Date of Patent: June 8, 2010Assignee: Emerson Electric Co.Inventors: Thomas B.

Patent number: 6729390Abstract: A method of controlling a heating system including at least a first stage heat pump and a second stage auxiliary heater, and a control that implements the method. The control shuts off the first stage heat pump during cold outside temperatures without the need to directly sense the outside temperature. The method includes selectively turning on the first stage heat pump or the second stage auxiliary heater based upon a measure of the amount of time at least one of the stages was on verses the time neither of the stages was on. This can be implemented with a counter that increases when neither the heat pump nor the auxiliary heater is on, and that decreases when either the heat pump or the auxiliary heater is on.Type: GrantFiled: June 1, 2001Date of Patent: May 4, 2004Assignee: Emerson Electric Co.Inventors: Bartholomew L.
