20100106329 | APPARATUS AND METHOD FOR CONTROLLING AN ENVIRONMENTAL CONDITIONING SYSTEM - An apparatus for controlling an environmental conditioning system serving an indoor space and having at least one environmental conditioning device coupled with a communication bus structure includes: (a) at least one user interface coupled with the communication bus structure for effecting access to the system by a user; and (b) at least one controller coupled with the communication bus structure for effecting operational control of the system. The at least one controller communicates on the communication bus structure with the at least one environmental conditioning device, the at least one user interface and any other devices coupled with the communication bus structure. The at least one user interface communicates on the communication bus structure with the at least one environmental conditioning device, the at least one controller and any other devices coupled with the communication bus structure. | 04-29-2010 |
20100050108 | DISPLAY APPARATUS AND METHOD FOR ENTERING A REMINDER IN A CONTROL UNIT FOR AN ENVIRONMENTAL CONTROL SYSTEM - A display apparatus for a control unit in an environmental control system includes: a display area presenting a plurality of first loci, a plurality of second loci and at least one third locus; each respective first locus of the plurality of first loci being responsive to pressure for effecting a respective response; each respective second locus of the plurality of second loci presenting information using a fixed segment data format; at least one third locus of the at least one third locus presenting information using a dot matrix data format. | 02-25-2010 |
20100050075 | DISPLAY APPARATUS AND METHOD FOR A CONTROL UNIT FOR AN ENVIRONMENTAL CONTROL SYSTEM - A display apparatus for a control unit in an environmental control system; the display apparatus including: a display area presenting a plurality of first loci, a plurality of second loci and at least one third locus; each respective first locus of the plurality of first loci being responsive to pressure for effecting a respective response; each respective second locus of the plurality of second loci presenting information using a fixed segment data format; at least one third locus of the at least one third locus presenting information using a dot matrix data format. | 02-25-2010 |
20090249812 | APPARATUS AND METHOD FOR DRAINING CONDENSATE - An apparatus for draining condensate accumulated by an air handling unit element, the element presenting a footprint area, includes: a substantially unitary plurality of surfaces oriented between a first level and a second level and bounded by a peripheral wall. The first level is generally higher than the second level in an installed orientation. A first surface is situated substantially at the first level and is generally horizontal and presents a generally planar expanse generally coextensive with the footprint area in the installed orientation. A second surface generally extends from the second level at a first end of the apparatus to the first level at two loci separated by the first surface at a second end of the apparatus opposite the first end to orient the first surface in a generally nested relationship with respect to the second surface. At least one third surface joins the first and second surfaces. | 10-08-2009 |
20090127346 | METHOD AND SYSTEM FOR CONTROLLING A MODULATING AIR CONDITIONING SYSTEM - A method for effecting cooperation between a modulating air conditioning system and a two-stage thermostat for satisfying an air conditioning load demand in a conditioned space includes: (a) operating the thermostat in a plurality of succeeding operating cycles to issue a first call signal or a second call signal indicating a first or second stage operation by the air conditioning system; the first and second stage operation being effected according to a first operating regimen to satisfy the air conditioning load demand; (b) operating the air conditioning system in response to the first and second call signals; the air conditioning system operating at a first power level when receiving the first call signal and operating at a predetermined second power level when receiving the second call signal; the first power level being established by the air conditioning system according a second operating regimen. | 05-21-2009 |
