Ec 840 Woes

[Nik]

Hi.
My EC840 display in my Autotrail has frozen at 0855, it's now 2220. We had a power EHU problem and the system went off. Having turned things back on the display is now frozen and I cant change anything. I cant get to the Autotrail logo to try a reset. I have switched everything off and gradually brought power back to the various systems. My ec500 unit seems ok having done the initial test following hookup. Water, heating, lights, water pump are working ok but I can't get any electric/water ' level bar graphs'. I just get a beep when I press any of the buttons on the right of the display.
Any advice grateful received.
Best regards.
Nik

Have you tried doing a full system shutdown or holding down up \ down buttons until the Dealer Setting menu comes up?

Try disconnecting EHU then full shutdown ec500, wait 5mins then power up ec500?

Thanks both.
I have tried pressing and holding the control buttons, it beeps but nothing else happens. I will again try a full disconnect and shutdown a bit later when it stops raining here in Sunny? Hastings.
Thanks again.
Nik

Hi. Nic in my autotrail when the control panel freezes up I disconnect it from the power for a few minutes 2 small screws and a plug to come off let it rest for a few minutes and when you put it back together you should hear a little beep then everthing goes back to normal.

Any luck yet Nik?

If all else fails, click the front bezel off, remove the screws that hold the panel in place, and gently pull the main plug out of the panel
leave on the side for a while, then refit

Would the shutdown mode on the main panel not achieve same, John? Dealer told us it powered down everything except the alarm \ tracker but would believe a man who's disconnected and recollected every wire with enough left over for, eh......., over them.

No mate.. It would if the thing had not locked up but with the wee processor all baffled it is unlikely

Some panels also have a button battery ( mine has not but a lot do ! ) if you have a button battery hook that out too !
