Grundfos 3 speed Circulator
I grabbed the 3 speed circulator on my hot water furnace and, when I did so, I accidentally switched the speed setting. I really don't have a clue what speed it should be on. What info do I need to provide in order to figure out what the proper speed is for this thing...It's a single story, 1000sqft house with a Burnham P204-W Furnace. 8 regular room radiators. Thanks for any info you've got.

More info
Here's the model #, etc.
Type UPS 20-42
Speed 1 - A=0,42 Winp=50 RPM=1800
Speed 2 - A=0,60 Winp=70 RPM=2300
Speed 3 - A=0,85 Winp=95 RPM=2620
60hz
What do all these numbers refer to?
Thanks

That information shows how fast the pump spins and how much electrical current it uses.
With the 3 speed Grundfos, speed 1 pumps far less water for a bit of electrical savings and speed 3 goes just a bit faster than speed 2 and adds noise.
If you're in complete doubt use speed 2. Who installed it? They should know...
