  1. Had the same issue... Installed pump, only turned on dip switch for 1 speed main pump. It assumes your circ pump is the low speed, and main is the high. Turned off, flipped 2nd dip switch for circ pump, had both speeds, but got HL when heat was called for....got annoyed, put it back to no pump. Read this thread, shut down, set switches correctly, reset memory, off it goes. 24 hr circ, low speed main on heat cycle. Thanks fellas.
