I have a small room with 6 lights on 2 circuits. They are controlled by 1 ceiling mt occupancy sensor and 1 low voltage momentary switch (manual on, auto off) The builder had originally installed 2 OSP20-RDH power packs and wired them in parallel. They apparently worked for several months but the second one has since stopped working. I understand that they should not have been wired this way, (they had connected to red +24v wires of the 2 power packs together) but I can not find a wiring diagram for this configuration. If these are not the correct products for this application, what products do I need and how do I wire them?
