You can use Output 1, you just need to program it as described in my first reply. The negative from the relay is connected to the output, the positive of the relay goes to the 12v aux supply
Just on Wintex now and all seems straight forward, only thing I'm not sure of is how to program the 3 zones that I want to trigger the lights into "Zone Group 1"
When I click on Zones & Attributes I don't see any options to do this or is it somewhere else in the settings ?
