Wavysea users?

[Delphinus]

I'm having some issues with a Wavysea unit I just bought.

What happens is that it seems to run fine for a few hours, but at some point it starts to "drift" away from its setpoints.

Ie., I'll find it turned almost backwards pointing at the back glass.

One thing that I'm doing is that I've mounted a Seio pump to the output. I'm wondering if I've either exceeded the weight capacity of the motor or if there's something else that needs to be addressed.

Unfortunately I don't have the manual so I don't know if there are any troubleshooting tips or any tips like "Don't try using this with a Seio because it won't work."

I don't think the Seio is any heavier than a Tunze though and I thought there were lots of people who have their Tunzes on a Wavysea.

Anyone have any suggestions?

I guess I should maybe fire off an email to the Wavysea people to see if they have any suggestions..
