CONNECT TRANSFORMER TO CONTROL BOARD
NOTE: All power wiring should be on a dedicated circuit, calculated using NEC
guidelines. Local codes and conditions must be reviewed for suitability of wire
installation.
EXTERNAL RECEPTACLE
The transformer can be plugged into a receptacle external to the control box.
Run low voltage wire between the transformer and control box.
NOTE: The transformer must be located in a dry location that is protected
from weather conditions, such as inside the house or garage.
This will create more space in the standard control box for accessories.
Connect 120 Vac directly to the control box and plug the transformer into the
receptacle inside the control box.
