You might also have a safety switch in line with your controls as in low water, flame roll-out, flue spillage or stack damper open. Circulators can be set to run continuously (rare), when burner comes on, or when boiler gets hot. Try the stat as HK said also follow the stat wires to see if they go through anything else and bypass it to test if it does.
