Caution: Disconnect power from the control board before beginning any wiring.
Each existing wire must be left connected and if the SOLO KIT connection uses the same contact as other wires, the new wires must be added to those already present in the same contact.
The connections to be made are:
Control unit terminal → SOLO KIT terminal
14 → CH1 CM
13 → CH1 NO
10 → 12/24V
9 → GND
