Connection diagrams are provided in the download area or in the box which came with the
Pro Controller.
Please download and read the operation instructions carefully before use (see attached)
Top Tip: The controller has a 4-pin plug connector that plugs directly into the heater loom. This
controller works via the CAN Network, therefore the pro needs to read the heater first.
1. You MUST connect the heater which has a 20amp fuse first for about 30 seconds.
2. Then connect the controller 5amp fuse last.
The photo on the top shows the Pro Controller 4 pin connector connected to the heater loom, its plug
and play. The photo on the bottom shows the Pro Controller connector and an extra set of wires which
are for older controllers and can be disregarded if you are installing the Pro Controller.
If fitting any other types of controllers, see instructions in the box that your controller came in.
Initial commissioning
The S2 D2L has an internal air temperature sensor built into the heater unit as standard.
The new EasyStart Pro Controller has a built-in external temperature sensor. When you power up the controller for the first time, the controller install menu will ask you if you want to use as the control temperature (EasyStart Pro) or the heater. It will also ask you to select where you would like to detect the display temperature (Indicator sesnor). The choice is up to you and this will depend on your installation needs.
As you can see from the top photo, the loom, which is teeing off the main loom, is for another external sensor which can be installed. This will needs to be programmed by us before we dispatch your heater.
Please contact us for more details.
