Hey Mike,
My relay control hasn't worked for many years, the relays crap out real quick out here -
Long story short H/W is on a 20A MCB, i wanna chuck in a Monotron relay and hook up some control times to stop the cylinder from constantly trying to recover, so when the 2 teenage daughters have used all the hot water .. etc
Probably looking at have it set to go off @ 05:30 - 07:30 and 18:00 - 21:00
Power bill is brutal at the moment avg 1250Kw p/m for last 4 months.
Back at school - so oldappy again - inspectors this time :-)
