You have a bad relay. You should be getting 240v between L and N. (L and N are both loads, no neutral) If the relay for N is turning on and off correctly, you can move the wire that is in L down to the main terminal block. If N is on the right of L, then put the wire from L onto the left side of the main terminal block.
Your circ pump will be receiving 110v all the time, and will still work normally by the use of the relay that is still working.
