The CoolMaster Gateway is a versatile bridge device that interfaces VRV/VRF air conditioning systems via RS232 or USB with devices like home PCs, embedded PCs, home automation controllers, and building management systems with the purpose of easily monitoring and controlling essential air conditioning parameters.

The carbon dioxide (CO2) transmitters can raise energy-saving efficiency, analyze indoor air, and monitor CO2 levels in underground parking facilities and tunnels, said the company. The transmitters detect a high concentration of CO2 before it poses a health risk.

U.S. commercial building owners could save an average of 38 percent on their heating and cooling bills if they installed a handful of controls to make their HVAC systems more energy efficient, according to a recent report.

Multiconfigurable, the Multi-Sense®-231RS is a wet-to-wet differential pressure transducer with remote sensors. With availability in conduit and cable versions, the pressure transducer offers four unidirectional and bidirectional switch-selectable pressure ranges. Each unit also features field-selectable output choices.

Occupancy scheduling without an energy management solution is performed by the Wi-Stat IIIp-S, a standalone programmable pneumatic thermostat. The thermostat is designed for easy retrofit to existing two-pipe pneumatic HVAC infrastructures without disruptive and expensive rewiring.

Business and building owners often face a dilemma when considering replacing or updating their HVAC system. Too often the recommendation is to retrofit an existing building with energy-efficient HVAC in order to save money on energy costs, but then the question arises — how to fund the investment?

Added to the WattNode® family is the WattNode BACnet® meter (MS/TP), which offers cost-effective energy and power metering for building automation communications protocols. The meters provide line-powered single- and three-phase wye or delta configurations up to 600 vac and 6,000A.

Designed to maximize energy savings in commercial buildings, the VFD Core provides a solution for contractors that works in 95 percent of HVAC applications and can be programmed in minutes, said the manufacturer. Increased memory allows for four parameter sets to be stored in one keypad for quick upload and downloading.

This roundup showcases some of the myriad products that can be used in high-performance buildings, from controls to components and equipment. 

For use with the gas-fired boiler products — KC 1000, all Benchmark, and Modulex boilers — the AERCO Control System (ACS) provides the contractor with the key component to sell a complete combination system consisting of AERCO boilers, SmartPlate, and Buffer Tank, said the manufacturer.
