The front push button simply cycles between R1,R2 and T (total). Anyone know how to easily check the actual clock and what Economy7 on and off times were set ?.

Our supplier assumes the low rate times and has no idea if the internal clock adjusts for winter/summer !. There is also confusion re a red LED on the front. It pulses per every W/h used yet some think it stays on during low rate, others that it stays on when the current falls below a certain level (and stops metering).

I found one manual online but they want an account creating with full credit card details !?, no chance.
 
I used to test the firmware and write the config files for these meters :p Was quite a while ago though. What you see in the display cycle is set by the config file. To change that, you'll need an app called meter utility and a flag probe. Also the config file sets whether the meter clock adjusts to dst. Regarding the led, it will pulse while the meter is registering energy, but will come on solid after a while of non registration.

Thanks !. Noticed this morning the 100A red led is on ??? (still at 8:30am). Boiling the kettle made no difference. Any idea why it's on ?
 
Totally depends how it's been configured. Shame I no longer work at L+G or I could have looked your meter up and given you all the configuration details. The red light on 100A doesn't mean you are using energy though, just that the 100A circuit is closed.

Yes the 100A circuit yet it appears it may relate to the cheap rate time too. I've read posts on other forums where folk have placed light sensors over that LED to drive an external indicator for cheap rate time !
