Welcome to Somfy’s IGC 4n1 motor controller overview. In this video we’ll cover the basics of the IGC 4n1 setup and operation.

Initial Setup

Somfy’s IGC 4n1 motor controller provides individual and group control for up to four Somfy technology AC motors with up to three intermediate positions per motor. To control connected motors and access intermediate positions the DecoFlex dry contact keypad is required. Each controller supports four individual keypad ports as well as two master ports.

These terminals are where motors connect to the controller. These are configuration dip switches for individual keypads and master ports. These are ports for master control, including daisy chaining and master keypad control. And these ports are for individual keypad control.

This is for 110 and this is the motor select button required to set settings to keypads.

Configuring Keypads and Operation

Before programming the controller and keypads, all motors must have their limits set and be wired to the terminals. When powered up for the first time, all motors should move to their upper limits.

Each controller supports four individual keypad ports as well as two master ports. Each port can be configured to control a combination of connected motors by turning on and off the appropriate dip switches.

To configure which motor a keypad controls, first plug a keypad into an individual keypad port. Next, select which motors you’d liek the keypad to control using the appropriate set of indivial control dip switches.

To finalize your settings, press and hold the motor select button until the green LED turns off and then release. Confirm your selection by testing from the keypad.

To configure a keypad for master control, connect it to one of the master ports and select the motors to be controlled using the master control dip switches. The controller includes pre-set motor positions of 25 percent, 50 percent and 75 percent, but these can be adjusted as needed.

Daisy Chaining Controllers

Multiple IGC 4n1 controllers can be linked together for simultaneous control of connected motors from a single keypad. Simply connect cat 5 cable with the correct pin out in an available master port of one controller to the available master port of a second controller. Configure the master dip switches of each connected controller as desired.

Now a single keypad connected to the master port of a single controller on the system can control motors connected to every other controller.
