You should be aware that the ECM-1240 may be expanded to monitor as many home panel circuits as required. It should also be noted that it is a good idea to group certain panel circuits sensors on a single channel providing a grouped consumption value such as:
- Bedroom outlets
- Outdoor Lighting
- Kitchen Counter Outlets
Doing this will reduce the number of channels required, leaving individual channels to more important energy guzzling loads such as A/C systems, Washer, Dryer, Water Heater, etc.
Select an Energy Monitoring System using the steps below:
1. Determine your CT requirements:
The CTs (current transformer) are the sensors responsible for picking up the electrical current from various panel loads, be it the total panel current and or the branch circuit current. This step will allow you to determine which loads you can monitor and the CTs required. This will also help determine how many ECM-1240 devices/channels will be required to perform the desired monitoring.
2. Determine the communication destination and method:
This section allows you to determine where the data will be collected and how it will be viewed. Once you have determined this, then the hardware selection can be done to provide the communication path to the destination.
3. Select the package that best suits your requirements:
Various ECM-1240 packages are available to satisfy various needs. Select from the existing packages and options.
Make sure your service is not 3-phase or powered from two phases of a 3-phase source. The ECM-1240 is designed to monitor 120V/240V split-phase residential panels and panel circuits only.
