摘要： 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 desired 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 desired heating level.

摘要： 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.

摘要： A thermostat for an environmental control load that includes a temperature sensor, a timer, and a controller, and a method of controlling the thermostat that allows temporary system outages including, but not limited to, outages caused by lockouts or failure of pulsed relays to operate, to be corrected automatically, by the thermostat itself. The environmental control load may include a heating system such as a heat pump or a millivolt heating system, although the thermostat and its method of operation could also be employed with cooling systems, or heating and cooling systems. The controlled load may be one that has a "lockout" mode to prevent activation when a problem is detected, such as a reduction in gas pressure. The temperature sensor detects whether, for example, a request for heat issued by the controller has been satisfied, or alternately, if the ambient temperature has risen within some period of time, usually about two hours. If the ambient temperature has not satisfied this condition within two hours, the environmental control load is turned off, and then on, to recycle and overcome the lockout condition, if the load is resettable and the condition causing the lockout has passed. This resetting may occur only once, or may be repeated after another period of time, with the repetitions optionally being limited in number. The thermostat can safely be used without noticeable degradation in service even with nonrecyclable systems.

The sensor includes a non-planar rotary input transformer having a stationary primary winding and a rotary secondary winding, both mounted coaxially about a common axis. A transmitter is mounted to the input shaft for rotation therewith and carries, on one axially directed face, a coil set of series connected coils arranged in an annular array about the common axis. A receiver is axially spaced from the transmitter and is mounted on the output shaft for rotation therewith about the common axis. The receiver carries, on an opposing axially directed face, first and second sets of series connected coils each arranged in an annular array about the common axis and with the coil sets being electrically displaced by 90.degree.. First and second non-planar rotary output transformers are provided respectively having first and second axially spaced primary windings coaxially surrounding the axis. The first and second output transformers respectively include first and second stationary secondary windings spaced radially outward from and coaxially surrounding the first and second rotary primary windings.
