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 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 motor start circuit for an AC induction motor employs a DC relay whose NC contacts are placed in series with the start capacitor. A half full-wave rectifier arrangement has an AC input connected to the junction of the relay switch and the start capacitor, and DC outputs applied across the relay actuator coil. In the event of intermittent application of power to the motor, any residual charge on the start capacitor will feed current to the actuator coil to hold the relay switch open until the residual charge has decayed sufficiently, to avoid damage to the motor from capacitive discharge. A high magnetic retentivity core can be used to hold the relay off for sufficient time for stored energy to dissipate.
