Abstract: The invention provides for a controller such as a thermostat for an HVAC system having a housing having a circuit board and a display screen, the display screen having at least one alpha-numeric icon and a group of touch pads having at least two displayable touch pads. A microprocessor provided for controlling the display screen. A sole mechanical button or switch is mounted in the housing and the button has a first end and second end and a touch surface extending between the first end and second end. The sole mechanical button signals the microprocessor in order to adjust the alpha-numeric icon(s), so that the combination of inputs received by the microprocessor from the group of touch pads and sole mechanical button provide for each and every adjustment required for all of the operational functions of the controller. The mechanical button may be a rocker switch. The controller may also include a navigation button.

Abstract: A display category icon displayed on the display screen is provided in a first segment location, the category icon including one of time, day, temperature, humidity or setpoint category; and each category icon having at least dual functionality including a first function and a second function and the second function programmed to display in sequence following the first function. Control logic allows a user to select a first category icon, then at the next step, the microprocessor can initiate a first function paired to a first category icon. At the next step, the user selects the first category icon again and in response the microprocessor will initiate a second function paired to a first category icon to finish the process.

Abstract: The invention provides for a controller such as a thermostat for an HVAC System comprising a housing having a circuit board and a display screen, the display screen having at least one alpha-numeric icon and a group of input control areas. A microprocessor is provided for control on the display screen. Buttons are pressed in order to program set-points of the thermostat so that seven days may be programmed simultaneously. The display includes a seven-day icon so that the user can program the thermostat set-points rapidly (e.g. setting time and temperature settings with minimal steps). The user may activate a first programming mode wherein the activating occurs by depressing a programming-mode button for a first pre-selected duration in order to select a first day for setting the conditioning mode.

Abstract: A rotary disk humidifier of the type that has multiple parallel spaced disks rotatably mounted in a water reservoir in a housing with controls for maintaining the water level in the housing to obtain an optimum wetted disk area above the water level exposed to air flow to achieve optimum humidification. At one theoretical extreme, the water level is at or above the center of rotation of disks decreasing the area of the disks exposed to free air flow through the housing. At the other theoretical extreme with the water level just at or slightly above the outer diameter of the disks, there is a grossly insufficient wetted area of the disk to approach the optimum area. Between those extremes there is a mathematical optimal range of the ratio inner wetted diameter of the disk Ri to the outside wetted diameter of the disk Ro (or the average outer diameter of the disk—the disk may not be circular) of about 0.30.

Abstract: A thermostat designed to accommodate service graphics after sale by the manufacturer directly or indirectly to the installer for installation at the ultimate consumer's location. The thermostat housing has a compartment door that is appropriately sized to receive the service graphics of the installer. The installer purchases the thermostat with no graphics and at his option orders replacement doors with his personalized graphics imprinted, from the manufacturer or its agent, and replaces the original doors with the replacements before selling the thermostat to the ultimate consumer. The doors themselves are unique in that upon outward manual flexure of the door panel a pair of connectors tilt out of recesses in the housing permitting easy removal of the doors.
