KoolKey is a gateway and programming device to:
• Connect the Danfoss electronic controller to a PC and act as a gateway when working online using
the KoolProg® application on the PC.
• Act as programming key to program parameter settings (conguration) into the Danfoss electronic
controllers in the production and eld.
Supported controller types:
1. ERC 111, 112, 113 2. ERC 211, 213, 214
3. EETc 11, 12, 21, 22 & EETa 2W, 3W 4. EKF 1A, 2A
KoolKey as a Gateway
Gateway mode makes it possible to work online with the connected
controller through KoolProg® on a PC.
KoolProg® allows following functions:
• Set Parameters – Create, view and edit controller settings.
• Copy to Controller – Program settings le created oine to the
connected controller.
• Online service – Monitor real time operations of the controllers and
make adjustments to the parameter settings while connected.
Connection:
• Connect the KoolKey using a standard USB cable to the USB port of
a PC installed with KoolProg® software
• Connect the controller to KoolKey other end using the interface cable
of the respective controller type
• The controller gets power from the PC via connected KoolKey
(Refer to the KoolProg® User Guide for detailed instructions on how to use KoolProg.

KoolProg®as Programming Key
The programming key function is used for transferring parameter
settings les from the KoolKey to the controller and vice versa.
Transfer or copy the parameter le in below format to KoolKey like
any other storage device.
We recommend to save only the le intended for the target
controller.

a. Steps to program a powered-up controller:
1. Connect the KoolKey to the controller communication port (TTL/di
port) using an interface cable.
2. Power up the controller using 120 V/230 V power supply.
3. Move the slider switch to required position and short press (1 sec)
the start button to transfer data.
4. After successful data transfer, switch o the controller power
supply and remove the KoolKey.
Note: While programming EET compact (EETc) and EKF controllers,
KoolKey requires to be connected to a power source as mentioned in
Fig. 4.
b. Steps to program an unpowered controller
(write function only):
1. Connect a Power bank or a 5 V power supply to KoolKey USB port.
2. Connect the Koolkey to the controller's TTL/di port using an inter-
face cable.
3. Write function gets initiated as soon as the KoolKey is connected
to controller (no need to press the start button).

Warning:
1. Ensure to disconnect non-isolated controllers (ERC 11X & EET) from mains power, before connecting to KoolKey.
2. Do not leave the interface cable hanging from powered-up controller.

function
a. Write function:
• Move the slider switch to“Write” position
• Short press the start button (1 s) to

Note: When KoolKey is connected to a
power bank, the write functions get initiated
automatically as soon as the KoolKey is
connected to a controller without pressing
the start button.
