@MikeP Thanks for your response.  You were on the right track.  This particular switch isn't a three way but there is a three way in this circuit.  I wasn't taking that into account.  So I solved the issue by identifying the load line and connecting it to the correct live lines so that the other single pole switch in the circuit, the one that wasn't working before, was getting the load even when my HS200 isn't on.  Thanks for pointing me in the right direction.  (by the way I'm a novice so forgive me if I'm using terms incorrectly)
