Abstract: A wall apparatus (1) for controlling utilities that can be installed at an internal cavity (2) of the wall itself in which the electrical connection cables to said utilities are present, wherein said apparatus (1) comprises a wall support frame (6) superposable on an access mouth of said cavity (2) and comprising a fixing means (8) to said cavity (2), and an electronic device (5) for displaying graphical symbols mounted on the support frame (6). In particular, the fixing means (8) of said support frame (6) is configured to fix said frame in at least two different fixing positions and displaced with respect to said cavity (2) so that the surface dimensions of said electronic device (5), mounted on said support frame, cover said mouth according to the shape and size of said cavity (2).

Abstract: A zone control panel that is easy and intuitive to use and to program. In some embodiments, a zone control panel may be configured to have an easy to use, single level menu structure with, for example, a configuration mode and/or a checkout mode. The configuration mode may, if present, include a number of menu screens sometimes without any sub-menu levels. Likewise, the checkout mode may, if present, include a number of menu screens sometimes without any sub-menu levels. A mode selector may be provided to select a particular mode, after which, the menu screens that correspond to the selected mode may be sequentially displayed to the user. Other features and aspects are also disclosed.

Abstract: A wall mountable connector for securing a thermostat to a wall is disclosed. The wall mountable connector provides electrical connections between the wall mountable connector and a plurality of field wires that are operably coupled with HVAC equipment. The wall mountable connector also providing electrical connections between the wall mountable connector and the thermostat. The wall mountable connector includes a door that is movable between an open position in which the electrical connections with the field wires are accessible and a closed position in which the electrical connections with the field wires are not accessible and/or visible to the user.

Abstract: An apparatus for controlling the operation of a HVAC system, where the apparatus is adapted to be releasably connectable to a thermostat sub-base assembly connected to an HVAC system. The apparatus is configured to be releasably connectable to the connector pins in a manner such that the apparatus may be slid onto the sub-base and easily removed without any disconnection of wiring. After completion of all construction, the apparatus may be removed and saved for future use, and a new digital thermostat may then be slid onto the connector pins of the sub-base.

Abstract: A thermostat, in particular for electric household appliances, including a mechanical switch and an analog regulating circuit having a variable-ratio reference divider. The reference divider includes a reference resistor and a variable-resistance resistive element; and the mechanical switch connects the variable-resistance resistive element to the reference resistor.

Abstract: The invention relates to an electric temperature setback device which is placed in proximate relation to a conventional thermostat and is operatively controlled by a timing device for providing local warmth to the thermostat at pre-determined times and for pre-determined intervals. The setback device includes spades with integral female lamp connectors for arraying a plurality of incandescent lamps in series across an electrical circuit. By so doing, the voltage to each lamp is proportionally reduced, decreasing the filament temperature of each lamp and thereby increasing the amount of heat energy produced proportional to the amount of light energy produced.

Abstract: A control device adapted to select a set-point temperature for a condition responsive device. The control device has temperature selecting means rotatable through a preselected temperature range generally between a pair of opposite rotated positions, and resilient means is disposed for engagement with a part of the temperature selecting means upon rotation thereof in response to a rotative applied force from one of the opposite rotated positions toward the other thereof so as to arrest the rotation of the temperature selecting means in a predetermined rotated position between the opposite rotated positions. Means is movable in response to another applied force thereon for driving the resilient means toward a displaced position disengaged from the part of the temperature selecting means, and the temperature selecting means is thereafter further rotatable upon further exertion of the rotative applied force thereon from the predetermined rotated position toward the other opposite rotated position.

Abstract: A device for heating a room or building thermostat by radiant means or a combination of conduction, convection and radiation in such a manner as to cause localized thermal energy in the vicinity of the thermostat. The temperature of the area controlled by the thermostat is thus caused to be reduced by an amount approximately equal to the rise in temperature in the vicinity of the thermostat. The heater, as shown a small light bulb, is switched on by a timer for the time period during which the building or room temperature is to be reduced. The light is turned off when the area temperature is returned to the thermostat setting.
