Description
ECU-LV – use existing controllers to manage energy costs
Use existing low voltage controls: The Low Voltage configuration has a power cord that has to be plugged into a receptacle. The unit also has an external sensor coil that has to be installed around the wiring for the circuit or load to be managed. The unit has a low voltage relay on board, which can control an existing low voltage switch such as a thermostat to shut off the load. This unit is ideal for controlling thermostat or time clock controlled devices such as pool pumps, air conditioners and water heaters. The unit can easily be installed by a qualified cabling technician and requires no electrical wiring.
The ECU-LV is designed to be installed in parallel to a load with no electrical connectivity wherein the high amperage, high voltage load does not run through the unit. It is powered by a 110V source which is converted into a 6V AC supply by an on-board, UL listed transformer. The unit is housed in a UL rated plastic case and contains a printed circuit board based monitoring, analysis and communication system. The unit has connectors where low voltage cables are attached to feed signals from external coils to take external measurements from existing electrical wiring. There are also connectors to feed a low voltage signal to an external, existing relay for load management. The unit has an on-board FCC compliant radio for wireless communication.
HOW THE ECU-LV WORKS
- Overview
- The product uses up to, two external current transformers (CT1 and CT 2) to detect and monitor the electricity in the power cables. The Unit can be installed to monitor two separate circuits or one two-phase circuit. The on board TARAS digital energy metering cards (pat. 7555365) are able to translate the readings from the CT coils into values for power (Watts), frequency, voltage & current. This data is then relayed using RF wireless frequency of 2.4GHz to a remote Energy Gateway processor in an EMP or a Control Server that uses the system software to provide analysis and communication to execute decisions to turn loads on and off. There is one on-board, low-voltage relay, which has to be connected to an existing on/off relay at the equipment being controlled (for example a thermostat relay on an air conditioner) so that when it receives a low voltage signal to turn the load on and off it can trip the relay on the equipment. The ECU-LV, when integrated into a system such as innGAUGE will help in understanding of the cost of operating electrical equipment/appliances in a building and help the user manage consumption and therefore save on energy costs.
