AGH, to operate the boost function hold the green button in for approx. 3 secs, you should hear a loud click when a relay operates to start the heating. Hold it again for approx. 3 secs and it will click again to turn off. I just tried it and noticed that on the bottom row of the display, about 1/2 way in, is a capital L, when I turned on boost this started flashing then stopped when I turned off the boost. I'm guessing they're connected but, of course, don't know what the L stands for.
Having said that, when I first used the boost when the meter was fitted there was no relay clicking on or off BUT it still heated the water. I also read somewhere (or was told, can't remember) that you had to hold in the green button for 10 seconds (?). The old meter turned the boost off after 1 hour, I'm pretty sure this meter also turns the boost off automatically but whether it's an hour I don't know.
If you don't think it's working properly then by all means lodge a fault and get someone out to check it and explain how to use it (good luck with the last bit). It's not your fault if you don't have any information on how to operate the meter and if they try to charge you for a callout (I doubt they will) refuse to pay and tell them you will lodge a complaint with the ombudsman.
Yes, AGL are responsible for the meter but trying to get any help from them is almost impossible. They are simply not interested in helping the customer. This "forum" is monitored by them so by now they must be aware that many people are unhappy about the lack of user information available for this meter (and you can bet that there are many more who don't bother complaining - or know where to go to complain) but still the company does nothing.
I'm old enough to remember the days when customers were important to companies and complaints/concerns were taken seriously, sadly (with one or two exceptions) those days are a thing of the past.
