EasyStart Pro – combination options D2L/D4R/D5E

Important: Before you start connecting two heaters together, make sure everything is completely powered down and switched off.

If you want to use the Pro Controller with more than one heater, here’s how to set it up:

1. Connect the first heater:
   Plug your Pro Controller into the first heater’s wiring loom using the 4-pin connector (see Pic. 1).

2. Connect the second heater:
   For the second heater, join the CAN-BUS wires from the loom in Pic. 2 to the loom in Pic. 1.
   Make sure you connect the blue/red and blue/black wires between both looms.

3. Power up and group:
   Once the wires are properly connected, power on the Pro Controller.
   It will prompt you to re-group, and it should now detect both heating systems as Heater 1 and Heater 2.
