Hi,
Just replaced my Bethlehem Dynatherm with WM WGO3 with Amtrol unit. It appears to operate somewhat differently (i.e. now low limit) and I am curious if it is operating correctly.
The burner comes on as soon as hot water is called for even if Amtrol is up to 115. Is this appropriate?
Is the burner set to come on as soon as one of my 4 zones calles for heat regardless of the boiler water temperature?
I have noticed the burner comes on for 50 seconds and then shuts off even though the high limit has not been reached. This happened 5 times in a two hour period last night. Is this appropriate? What would cause that to happen?

Many thanks,
Jim
