摘要： A three-phase power monitor operates a contactor between a supply of three phase electrical power and a three phase load. A phase integrity detector has three inputs connected respectively to the three phases of the electrical power. If a loss, reversal, or dissymmetry is detected, a photoemitting device is actuated. Actuation can also result from low or high line frequency. A power supply circuit is input with the three phases of power and has an output providing a dc level corresponding to the voltage level of the three-phase electrical power. A hold circuit has a first time constant associated with it and attains a hold level when current is applied to its input, but reverts to a release level after this current ceases. An interrogator circuit is coupled to the power supply and to the input of the hold circuit and provides a periodic recharge current to the hold circuit at a period that is shorter than the period of the hold circuit. A high/low voltage level detector interrupts the periodic recharge current if the dc level is outside a predetermined voltage limit. A photosensor-based discharge circuit is optically coupled to the photoemitting device of the three phase integrity detector, and is electrically coupled to the hold circuit for discharging the time constant circuit thereof if a phase loss or phase imbalance is detected.

摘要： An arrangement for driving actuator coils for two or more driven devices employs a microprocessor or similar controller and an actuator driver circuit. The actuator driver circuit controls two or more relay actuator coils from a single microprocessor output terminal. This output terminal can provide a high, low, or pulse output signal. An amplifier switching device, such as a transistor, whose base is coupled to the output terminal of the microprocessor, drives the first relay actuator coil as its load. A rectifying diode is connected to one end of a capacitor and thence through a negative resistance device to a second relay actuator coil or other driven device. The coil impedances are selected so that the second coil has a significantly higher impedance than the first coil. When output pulses appear at the microprocessor output terminal, the transistor switch pulses on and off, and thus energizes the first coil. Flyback voltage pulses pass through the rectifier diode to charge up the capacitor until its voltage exceeds the threshold voltage of the negative resistance device. Then current flows to energize the second relay actuator coil. By selecting the appropriate pulse rate, the microprocessor can energize either or both actuator coils.

摘要： A touch-screen control panel interface has a dielectric flat or curved front panel and a printed circuit board with a front side and a reverse side which is the component side. Alphanumeric display module(s) or an LCD display and optional protective cap mounted on the reverse side of the circuit board are visible through window cutout(s) on the board. An array of LED indicators can be mounted on the back side of the circuit board and visible through cutouts in the board. Metallized capacitive pads on or adjacent the back side of the front panel at touch locations permit selection of various modes, functions, and settings. These pads may be formed on the flat front side of the circuit board, on the back of the front plate, or on an intermediate membrane. A microprocessor is connected with the various components and with capacitive pad. Icons may be printed onto the flat panel, in registry with the metallized capacitive electrode pads. A potting dam is formed of a back plate configured to adhere to the front panel and an open frame extending rearwards. Synthetic resin potting material fills the frame and hermetically seals the circuit board. Positions of the capacitive touch pads can be illuminated when active, as a guide for the user or operator. A second circuit board may be positioned in the frame directly proximal of the first circuit board, and optionally encapsulated.

摘要： A battery powered thermostat senses a battery voltage drop to a low-battery voltage level. At that point, the thermostat microprocessor provides a LOW BATTERY alert message, visible on the thermostat display. If the occupant fails to replace the power cells or does not notice the LOW BATTERY message, when the battery voltage drops further the microprocessor alters the thermostat set points. This reduces the number of heating or cooling cycles per day, and reduces the number of actuations of the latching relays in the thermostat, conserving remaining battery life. At a further drop in battery voltage the set points are changed additionally. Additional functions, such as second level heat, second level cooling, and fan speed, are disabled. The change in heat or cooling cycles induces the occupant to check the thermostat where he or she will notice the LOW BATTERY message.

摘要： A thermostat, of the type that employs latching relays to connect thermostat power to the various wires of the thermostat run, has a re-pulse feature that supplies latching pulses at a given interval, e.g., three hours, to ensure that the relays are in their proper state agreeing with the thermostat mode and the room temperature relative to the setpoint(s). In the case that the room air temperature is changing in a manner contrary to the current heating or cooling mode, which may indicate the latching relay has been knocked or bumped and needs to have its proper state re-established, the thermostat microprocessor issues pulses to the latching relay(s) more frequently, e.g., each 30 minutes, and the re-pulses may have a longer pulse width, e.g., increased from 20 ms to 25 ms.

摘要： A furnace controller circuit includes a microprocessor with input ports and output ports including ports to issue control signals for actuation of inducer, gas burner, and furnace blower. A temperature-actuated limit switch commences a furnace shut-down sequence when the temperature of the furnace heat exchanger exceeds a predetermined limit temperature, and then resets to permit a turn-on sequence. An LED visible fault indicator is coupled to the microprocessor to provide visible fault messages. A non-volatile memory device coupled with the microprocessor is operative to store fault indications when present. In the event of power restoration after power failure, the limit switch status and other fault status are maintained. A lockout period is computed based on length of furnace run time until fault and recent fault history. Limit switch and other safety faults are recorded and these can be weighted and ranked based on age of each fault occurrence. The stored fault data can be used to identify erratic furnace operations, such as short cycling.

摘要： A supplemental circuit board is provided for a furnace and air conditioning system to power the blower motor so that there is normal heat speed during a heat cycle, and normal, full speed when there is a normal cooling cycle. When there is a call for economy, dehumidification, or partial speed cooling, an inverter provides pulsating power for efficient reduced blower speed operation. An actuator circuit provides a blower-motor in-use signal, and a low-speed logic circuit provides a low-speed signal when there is a call for reduced speed cooling. In case of circuit failure, the arrangement defaults to normal speed operation.

摘要： First-order failure mode arrangement for driving an actuator coil for a switch element employs a microprocessor controller and a driver circuit that includes an amplifier switching device, such as a transistor, a capacitor that ac-couples the output of the microprocessor to a control electrode of the amplifier switching device, and the actuator coil which is tied between a voltage source and an output electrode of the amplifier switching device. The microprocessor also has a capability of interrogating the on or off condition of the switch element. The switch element can be, for example, the gas valve relay for a gas furnace. The switch element can be tested to ensure that it is capable of both closing and opening when directed, and to ensure that of the switch element is not locked or frozen into a closed condition. If any of the microprocessor output, the capacitor, the switch transistor, or the coil develops a short or an open condition, the drive circuit will be unable to provide drive current to the coil, and the microprocessor will terminate the actuation sequence, and shut down.
