Daikin VRV
I've just joined the site and I'd like to say hello to everyone. I've got an intermittent EO fault with a Daikin RSEY10GJV1. I've checked all the usual suspects but so far have drawn a blank. I spoke to a guy at Daikin UK today who suggested fitting some ''tell tales'' accross all the compressor overheats and fan klixons etc. Apparently they blow when the switch they are connected to opens making it easier to pinpoint the fault. Has any one heard of these devices, and do you know what they are called and where they are available from? I'd be gratefull for any feedback.
Regards, Nick.

With the EO code showing don't do anything until you've checked for continuity otherwise you will reset the system and the fault will disappear - until next time

Hi Guys,
Check out the Thread Daikin VRV's from 14-01-2006 in the air conditioning forum.
Have come accross they tell-tales before and they are useful for iscolating faults.
i assume they are available from Daikin although Frank will know better than i do
Regards

Re: Daikin VRV
Never had to use the tell tales and i know that they are not available from Daikin. I would recommend power off the system and switching to emergency which will run the standard compressor alone without the inverter allowing you to check the running current 95% of the time its either standard compressor overload or HP trip. Once you get the system running on emergency check that the valves are not passing through the inverter compressor allowing discharge gas back into the suction! If so your inverter compressor is dud! Hope this helps

Re: Daikin VRV
Isnt this just a clasic undercharge problem, overheating the compressor after prelonged use and resetting by the time the engineer arrives on site, Id stick abit of gas in and monitor for afew days, If problem goes away I would decant , pressure test and recharge with correct weight of gas. Or decant pressure test and recharge first off depends on what sort of contract you have.
