reg
Sorry, I'm doing another project, I'm in the air cond. business. I'm making a board for controing two driffrent thermostats with only one Air Cond. Because one thermstat is located upstairs and the other down stairs in a house. the man didn't like the idea of going upstairs and turning the system off or on, so he ask for other thermstat to be put down stairs. The board that I'm making will have two relays for each thermostat, two for down stairs and two for upstairs and one control relay. to switch from one and the other i will be using a three way light switch. thats why I asked if I can use the Reg. I know I have to add something else to the cict. I was thinking of using a 120vac to 24v vdc.
