Thanks Rhonda, Hal, Dagwood, liquidvw, and Wellco. What a consulting group! Let's see, at your respective billing rates, I guess I owe the board $600 for this question alone!!!! The Viking unit should work nicely. Again, I appreciate having ther ability to consult with experts like yourselves. It is totally awesome. It's one thing to look at products that are out there, it's totally another thing to have someone say "yeah, I installed that and it works well with your system". Excellent.
