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.
If the terminal marked "+24" (terminal no. 10) on the receiver is empty, but "+12" (terminal no. 11) already contains a wire, connect the red wire from the KIT to terminal "12".
The green wires instead must be added to the existing opening wires, which should be found on the first two terminals.
