Telkonet Inc.: Occupancy-Based HVAC Controller
The EcoWave™ occupancy-based wireless unitary HVAC controller is ideal for achieving the balance of energy efficiency and occupant comfort in fan coils, heat pumps, packaged terminal air conditioners (PTACs), and other unitary equipment used in spaces with unpredictable occupancy, such as hotel rooms, dormitories, residence halls, assisted living facilities, public housing, and condominiums, the company said. It can be installed as a stand-alone controller or networked with the ZigBee®-based EcoSmart Intelligent Energy Management System for cloud-based total facility management. The EcoWave system is comprised of two hardware components: the EcoAir™ battery-powered wireless display thermostat and the EcoSource™ HVAC controller, mounted at the HVAC unit. The controller has an operational voltage of 12-277 ac without the need for external transformers and proportional control outputs. Large internal data loggers record over 40 runtime metrics for measurement/verification and detailed analytics. An external temperature input can monitor remote temperature, and two dry contact pairs are available for door contacts or integration with BACnet® building controls.
