Arzel Zoning Technologywww.arzelzoning.com
The Universal ModuPASSâ„¢ is a stand-alone bypass system designed for any HVAC equipment and any zoning system. According to Arzel, barometric bypass dampers "float" open and closed to provide an "average" static pressure. This can cause problems with noise at one extreme and low airflow at the other. The Universal ModuPASS is designed to measure the static in the ductwork and position itself to maintain the pressure needed, it said.

Carrier Corp. is pleased to announce the launch of the Totaltouch line of touch screen thermostats. The thermostat is all-inclusive, installation is considered user friendly, and it is completely integrateable with most HVAC systems. The company said it is loaded with features.
Most heating and cooling systems are designed and installed to provide heat for the coldest day of the year. On other than the coldest days, heating systems are overheating, "just in case" it gets cold. This causes a waste of energy and uneven, short-distribution cycles of overheated transfer medium to the heated space - water in radiators, steam in radiators, or hot or cold air through ducts. Meanwhile, air conditioning systems similarly are operated and designed for very hot days. When it is less than very hot, there is over cooling and uneven distribution of chilled air. Uneven extremes result in the waste lost in the generation and loss in the ducts and pipes when the system is at peak output and the thermostat goes off. By adjusting limit temperatures, Exquisite Heat said it fine-tunes a home's system each hour to provide the exact heat replacement required. Leads and lags in heat are eliminated, it said. The end result is, as the company put it, a "truly intelligent relationship between a home or building and its heating or cooling system, which provides economy and comfort for all the occupants." Exquisite Heat pays for itself in less than two years and provides savings forever, said the company.
