BACnet is now an option on all Allied Commercial K-series packaged rooftop equipment. The module offers greater flexibility of unit operation and the K-series line is the first-ever Allied Commercial product to offer integration into (BAS) building automation systems, company sources say.
Available as a factory- or field-installed option, BACnet allows users remote control and monitoring of their building’s efficiency and performance. The K-series option is a BTL-certified device that ensures seamless integration with BACnet systems, along with password protection that locks out unwanted changes from within the space.
Daikin AC introduces the Intelligent Touch controller. The controller provides building owners, facilities/premises managers and maintenance operators refined and energy efficient control of Daikin VRVIII, VRVIII-S and/or mixed VRVIII/VRVIII-S/SkyAir air conditioning installations. With its user-friendly color icons and scheduling capabilities, this controller makes management of air conditioning units and other facilities equipment easy, even among multiple buildings.
Intended for use in conjunction with installations of up to 128 groups or zones, the controller is linked directly to the system via a Daikin DIII-NET connection without the need for a PC. The optional power proportional distribution (PPD-Optional) feature supplies the user with a reasonably calculated apportionment of the total power consumption by the Daikin air-conditioning system to individual units on the system.
The Ultra-Zone Model UZC is a 4-zone control panel that features auto changeover between heating and cooling modes.
The UZC controls single stage 2, 3, and 4 stage conventional, geothermal or dual fuel heat pumps, without the need for dual fuel kits. It also controls single or multi-stage gas, oil, and hydronic HVAC systems with single or two-stage cooling and constant or variable speed fan systems. ewccontrols.com
Sophisticated, yet simple to use, the ComfortNet CTK03 features include extensive wireless programming and monitoring capabilities, multiple commercial dehumidification options, advanced staging controls, customizable home screen and lockout, maintenance reminders and a host of diagnostics that can improve not only indoor comfort but energy consumption.
Automatic diagnostics can alert for potential issues, allowing building managers to resolve HVAC system problems before they turn into a loss of cooling or heating. goodmanmfg.com
Jackson Systems, LLC, announces the release of its newest product, the VCS ventilation control system.
The VCS is a fresh air control system designed to improve residential indoor air quality. This is accomplished by introducing fresh air through an intake damper controlled by the VCS logic panel. The VCS dramatically increases indoor air quality by decreasing VOCs. The VCS meets the ASHRAE 62.2 standard, and is backed by a five year warranty. jacksonsystems.com
Johnson Controls announces an enhanced version of its York Commercial Comfort Systems (YCCS), a broad range of mechanical systems and integrated controls for the commercial building environment.
Using YCCS, building owners and operators can network single-zone, constant-volume HVAC units, multiple change over bypass or VAV-zoned systems, or have a combination of both. Unlike complex and expensive building automation systems, YCCS are designed specifically for commercial unitary HVAC systems. YCCS application-specific unit controllers feature standalone functionality in a microprocessor-based device, providing internal time-clock functions for daily programming capability, holiday scheduling and automatic daylight savings time adjustment.
Bosch Thermotechnology introduces two new gas condensing Greenstar models for residential applications with AFUE rating of 95%: the Greenstar Combi 131 for space heating and hot water at up to 3.2 GPM and the Greenstar 79 for space heating.
Both wall-mounted units are available with venting options from Bosch;concentric up and out venting and polypropylene twin pipe for installation flexibility. The up and out venting option kit consists of an appliance adaptor, a 90 degree elbow and a telescopic termination that accommodates varying wall thicknesses.
Carrier’s popular GT-PX series is Carrier’s highest rated geothermal unit, featuring Puron refrigerant; a two-stage compressor for efficiency; variable speed blower for comfort; tin plated coil; microprocessor control; and a robust, insulated cabinet for quiet operation. The GT-PX series is available in vertical top flow, vertical bottom flow and horizontal flow, all with optional hot-water generator. In sizes from 2 through 6 tons. residential.carrier.com
The Tranquility 30 digital series is one of the most advanced, efficient, comfortable and environmentally friendly methods of heating and cooling available to homeowners, ClimateMaster says. Its advanced design includes two-stage compressor operation, variable-speed indoor fan, vFlow variable water flow technology and iGate communicating controls.
vFlow internal variable water flow technology reduces water pumping power consumed by 60-80% compared to traditional external pumping
The TGVX is Trane’s first true variable speed heat pump. Using a variable capacity scroll compressor, a fully dedicated communicating control system and built-in system performance monitoring, the TGVX delivers the ultimate in efficient and quiet comfort. With a cooling EER of over 40 and a heating COP over five, the TGVX can return up to four dollars of heating or cooling energy for every one dollar of electricity used. When paired with a variable speed loop pump, TGVX technology matches the earth’s energy to the exact needs of the home. A corrosion-resistant air coil, variable speed indoor blower and MERV 11 filter are standard with the TGVX heat pump. trane.com circle 162
WaterFurnace introduces the 7 series line, built using the latest technologies and highest standards. The 700A11 signifies innovations on multiple fronts – most notably as the geothermal industry’s first fully launched variable capacity residential unit and the only unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers, company sources state. These ratings are vastly greater than ordinary conditioning systems and 30% higher than current two-stage geothermal heat pumps.
