hi all just want to check this set up.
have 17th edition board (already installed)
have main switch then a VO on one circuit (hold fire read rest), 2nd breaker immersion circuit.
then first RCD unit which is fed via VO unit has half the house on it.
then next rcd that has some sockets on it & PV (3 circuits total).
installed immersun on system with wired clamp as tails enter board for CT clamp.
turned on immersun all flashing away ok for a week.
customer said that they woke early in morning & found alarm clock in bedroom not working, went down reset board found that immersun not working either, pressed reset on rcd unit nothing, (rcd fused spur installed by me for independant circuit protection) fused had blown & also taken out breaker they replaced fuse & reset light on for second then off again. i tested immersion all ok replaced RCD unit, immersun is blowing fuse & circuit breaker.
set up looks ok.
on another job.
previous to this with new immersun straight out of box (new type) had fault on immersun unit saying back voltage present checked all connections & immersion circuit that i had already done on intial testing before immersun was installed. got to set up page went through it's cycle of self test on 3rd go then blew fuse. rang immersun technical & was told new units will not accept any back voltage (old units no problem) mentioned that i had checked circuit & put new fuse in system went though set up with tech online bang again.
tech guy said that the immersun unit could not regulate it's output voltage & therefor was faulty would need new unit
lucky had spare unit on board installed fine.
installed loads of first units only had couple out of about 50-60 units, installed maybe 10-14 units now on second issue lot of money just to carry spare incase. also immersun are repairing units & sending out again.
anyone else had similar problems, or think there could be setup issue with immersun at top of post??
