Setting up external power supplies:
When installing several TouchOnes, all except one must be powered by external power supplies.
The positive terminal is connected by the red wire from the Wire Harness. To connect the negative terminal to the COM terminal on the control panel, cut a length of 0.5mm wire. The black wire from the Wire Harness must also be connected to the COM terminal. The remainder of the wiring is original.
Before turning on the TouchOne running off of the external power supply, configure the areas in the control panel, then address the TouchOne and/or keypad as required.
