Odd activity in apex (amp graph)

[duncangweller]

Hi all,

Now that the power is back on it looks like the tank fired up as normal for a few hours but for the last 2-3 hours the power looks like it has been dropping off and then resuming. I am currently in England and have no way of seeing my tank until the in-laws drop by and then email me with what they see.

Can anyone think of a logical reason as to why this would be happening?

My graph looks the same when the heater cycles on and off.

Dave sorted it. In-laws had got the return pump and heater outlets mixed up. When water hit 81° it shut off the return pump and as the heater was plugged into the return pump outlet it kept running. Thankfully he found it straight away.
