Are you using the frost stat for frost protection or as high limit for the header?

 

[Rob brazendale]

Frost peotection

Frost peotection

Have you got a pipe stat for the header or is there a high limit stat build in?

 

[Rob brazendale]

There isn’t one built in. We will have to get one.

It’s simple to wire if you break it down. It’s a lot of work to try and explain it or knock up a diagram. It might be easier if you do a diagram and I/we can tell you what needs changing etc if anything.

Appreciate that lee. I’ll post a diagram up tomorrow.
