The Efergy E2 Classic is easy to install and use. The sensor will clip onto your electricity meter, so it can measure the current that flows through it and measure your usage. Attached to this sensor is a wireless transmitter, which then transmits the reading to your wireless display or Wi-Fi enabled hub.
- Install the CT Sensors into your power meter fuse box.
There are a couple of options here, you can install the clamp either onto your mains incomer, this will check you overall power or you can install the CT Sensors onto a separate individual circuit like a Hot tub, Air-conditioner or solar systems circuit to measure individual power for an appliance or solar feed in.
Open the fuse box and look for the screws to take off the cable protection back plate. Once the plate is removed look for the cable you would like to monitor.
Most people like to monitor the power use for their whole house, this will be the largest cable it’s called the Mains Incoming cable. Clamp wherever it is convenient and place the transmitter somewhere safe and out-of-the-way. Power your switchboard board back up and check that you are seeing a reading of power usage.
There is no need for an electrician to do this power consumption meter install, as we are not disconnecting any wires. Please take care when removing any covers in your fuse circuit box. There are live cables here, either 110V or 240V or if using 3-phase power possible 415V. This is dangerous and electricity can kill so be careful. It’s a great idea to isolate all power beforehand from the main circuit breaker.
- Connect the Sensor(s) Jack Into the Transmitter
Plug in the sensor’s jack into the transmitter. Make sure you insert the sensor(s) jack first, then power on the transmitter. Open the Transmitter case and insert three AA batteries (not provided). If your fuse box is inside the house, mount the transmitter on the wall next to or above the electric panel.
- Link the Transmitter and the Wireless Energy Monitor
- Step 1 - Ensure three AA batteries are inserted in the transmitter and three batteries (AA for the Elite or AAA for the E2) are inserted in the wireless energy monitor. You can use either rechargeable NiMH or Alkaline batteries. Alkaline batteries should last longer but rechargeable will be cheaper in the long run. Make sure they go in the correct way.
- Step 2 - Push in the link button on the reverse of the monitor for about two seconds. The transmission signal symbol on the monitor will flash for one minute.
- Step 3 – You now have 1 minute to press the link button on the front of the transmitter, once done the transmission signal symbol on the e2 display will become solid.
The default value for the transmission frequency updates is 10 seconds. This means the transmitter is sending information every 10 seconds. You can change to the following the frequency by pressing and holding the transmitter button.
- 10 seconds, red flashing light
- 15 seconds, orange flashing light
- 20 seconds, green flashing light
If you change the frequency to 20 seconds updates, you will get longer run times before you need to change out the batteries in both units. The trade-off is your display will be frozen with the current power for 20 seconds. No big deal. I have it set to 20 seconds.
- Set up the Wireless Energy Monitor
Setting the time and date
The monitor needs to know the time and date in order to provide you with the correct historical information. Set the time and date as follows:
- Step 1 - On the back of the display you will find the time set Press and hold for two seconds. Time setup will flash up in the display.
- Set the hour to the correct time by using backward and forward Once correct you can press unit set button once to save the hours. Repeat for minutes, using the unit set button to confirm.
- Set the month by using the backward and forward Press unit set button to confirm and move to date set up. Repeat the process to set the year. Once you have the correct time and date have been set, push unit set button to save and exit. The Wireless Energy Display is now set up.
