PLEG controlling the immersion (Sir321)

Any one got any ideas why this is triggering the “TankOn” condition every minute or so?
It seems it’s firing the immersion switch all the time.

Thank you.

Since you do not have repeats … then this is because the condition is going false then true every minute.

Looking at the time stamps for the TankOn condition and it’s inputs … the following input looks like the cause:

auto   Auto Heating   Status   1   2015-06-21 14:49:42.502   2015-06-21 14:49:37.564

Who is changing this property ?

Thanks for the reply.

The auto heating Virtual switch is a manual action, no automation on that one. I use it to switch on and off if we go out for the day etc)
I triggered it to get the states right.

I haven’t fiddled today, so i’ll get the status report at 1300 today to see what it’s doing.

cheers.

i think i found the issue. Not PLEG at all.

The SIR321 has a temperature cut off parameter (number 5). That was set to 256, so it was tripping itself off early at about 30 degC. Increasing that now and it hasn’t turned off.

Thank you for the help though.

how do you set this “cutoff” ?

Vera support added the missing parameter. And set to 1000c
