Controlling HVAC with X10 Relay
I would like to turn off my AC when the Patio door and or windows are left open for 3 min. I am currently using Homeseer along with the Gemini Napco Plugin. I can detect the opening and closing of the door and window zones and then create an event to trigger an X10 command after 3 minutes to a Power Flash (which is an x10 relay). My main question is how to properly wire the Power Flash Relay to my Thermostat wires at the HVAC system so that I can make or break a connection that controls the AC withouth damaging my HVAC System.
