Telkonet’s EcoInsight is an intelligent thermostat with more than 125 configurable settings to control the efficiency of HVAC systems. It calculates room comfort by aggregating data like time of day, solar load, brightness, humidity, and occupancy patterns. Using the internal infrared occupancy sensor, the EcoInsight determines when a space is occupied or vacant and reverts to preset temperature limits or engages the integral patented recovery time algorithm to limit temperature drift, maximize equipment life, and maintain occupant comfort. The EcoInsight is equipped with a ZigBee transceiver to create a wireless mesh network that communicates with myriad wireless building control devices and the cloud-based EcoCentral Virtual Engineer Command Center. The EcoSmart network can also be fully integrated with BACnet control devices and equipment. The EcoInsight provides universal HVAC system compatibility and is easily installed on packaged terminal air conditioners, fan coils, heat pumps, split systems, and more.
