This installation covers Electrolux Compass Pro Single and Stack Dryers.

• Reader
  For stack dryers, the readers have back-plates that differ between the left and right versions:
  
  
  
  
  For single dryers, the readers use a special mounting bracket:
  
  
  
  
  
• Cable harness (3-wire)

1. Before proceeding, you should assign numbers to each of the machines in the laundry room/building. It is highly recommended that you place number labels on each washer and dryer machine.
   
   
2. Set the machine type and number using the DIP switch on the reader circuit board: 
   
   
   
   See DIP switch settings page to understand how to configure DIP switch positions to set the machine type (washer or dryer) and number. 
   
   
3. Turn machine power OFF!
   
   
4. Remove the coin drop if present
   
   
5. Connect the 3-wire harness to the green coin board inside the machine. The wire harness should have the wires labeled as GND(COM), 9V, and Coin. There are two variants of coin board: with screw terminals and without screw terminals. 
   
   In either variant, the connections between the harness and the coin board should be as follows:
   RED wire <---> 9V
   BLUE wire  <---> GND (ground)
   WHITE wire <----> Coin1 (or Coin2)

Variant 1: Boards with screw terminals
Use the connectors with screw terminal to make the connections as per below. In some cases the dryer may not have the connector shown on the left, and instead have the 2-pin connector that fits all the way on the right side of the board. This 2-pin connector has the same 9V and GND,  so you can use as another option for power.

Variant 2: Boards without screw terminals
You will have to splice the three wires to the existing cable harness as shown:



The result should look like this:

Left side and right side mounting plates are different.

Set pricing on the LaundroPortal.  The actual dry time is set on the dryer itself. Pleasure ensure that simulated dry time configured on the reader matches the actual dry time set on the machine. The reader sends exactly one pulse on the Coin input every time a card is tapped.
