HW4 activation
HygroGen2 version 2.0 installs HW4 version 3.2.0. If the code you noted in
not version 3.x, proceed to step (a) below. Otherwise, proceed to step (h).
a. To use HW4, you have 3 options. Either you can downgrade to HW4 v2.4, buy and upgrade to
HW4 v3 or buy the AutoCal Enhanced Feature set which includes HW4 v3. Please note, a
standard PC HW4 V3 licence will not work.
To downgrade to HW4 V2:
b. On the root of the USB installation stick is a file “HW4 v2.zip”. On a PC, right-click this file and
click “Extract to…" and choose the root directory of a USB stick, e.g. D:\ (i.e. not a subfolder e.g.
D:\HW4 v2). You can use the Installation USB stick itself. A folder “HW4 Update” will be created
in the root directory.
c. Safely remove the USB stick from the PC.
d. On the HygroGen2, go to the Settings screen, then select “Update Software” from the
“Updates” drop-down menu.
e. Select OK to boot the HygroGen2 into configuration mode.
f. Once the HygroGen2 is in configuration mode, insert your USB disk and select “Update HW4”.
NB: If “Update HW4” is greyed out, the folder “HW4 update” has not been found in the root of
the inserted USB stick.
g. Press OK to reboot.
Having obtained an HW4 V3 licence key or downgraded to HW4 V2.4, now enter the HW4
code:
h. On the HygroGen2, press the HW4 button. Select “Start HW4” and enter the code.
3.2.2 Installation of HygroGen2 version 2.1 (from version 2.0)

d. Once the HygroGen2 detects a USB stick with the controller software, the “Update HG” button
should become enabled. Press this.
e. Follow the on-screen instructions, accepting the default directory locations and accepting the
software terms and conditions.
