I haven't talked to my electrician today but I believe this was our original circuit "set up" idea.

One circuit board for 3 rooms.
1 Key Card Switch in each room (total of 3)
1 Circuit Switch for in-window 220V/650 watt Airconditioner (total of 3 switches)
1 Circuit Switch for Lights and Outlets (total of 3 switches)
1 Circuit Switch for Outdoor Building Lights (total of 1 switch)

Grand total, 7 switches.

I want the key card switch to control the aircon circuit and indoor lights/outlet circuit. To be safe I want a relay/contactor to handle the airconditioners (so 1 for each room for a total of 3). Is it possible to have this set up as I described?

I ask because a relay is $10 each and one central circuit board is no more than $100 (total of $130). His method is to buy 3 smaller circuit boards with a relay inside of them for $80 each ($240 total). I'm trying to cut costs and simplify my life with 1 circuit board.

Your electrician is probably correct, AC plus lights plus what ever elese may be plugged in not to mention a hair dryer in the bathroom would require more circuits.

Just get a 120vac coil three 30-40A) pole contractors for $15 and use the three poles to break various circuits. No need for electronics and circuit boards.

@curiousb

Are you confirming I should do what I described with the 30-40 amp contactor?
