Here is the info for the mechanical relay I purchased.
This is a single pull double through 24VAC coil open style mount relay. I have tested it with my os controller and it does open and close. One the FW has been updated to allow the dusk to dawn controlling, I will test it further.
The price of the relay is about $19. The solid state ones with the heatsink would be similiar in pricing but I opted the mechanical relay.
