WARNINGS
If the maximum temperature or limit temperature of the solar collectors is exceeded, the
controller signals the problem with the symbol .
In case of sensor, flow meter or collector’s circulation pump malfunction, the controller
signals it with a symbol .
You can determine the reason for the warning by using buttons and for
checking all data.
Warning disappears from the display as soon as the reason for alarm
or malfunction is cleared.

INITIAL CONTROLLER SETUP
KSW-E, KSW and KS2W differential controllers are equipped with an innovative solution,
which allows initial setup of the controller in only two steps.
When you connect the controller to the power supply for the first time, the software ver-
sion and company logo are shown. Next, the first step appears on the screen.
Using buttons and you select the required language.
Press the button to confirm the selected language.
After selecting the language, the controller requires con-
firmation of the selection by pressing the button.
If you accidentally selected the wrong language, go
back to reset the language by pressing button .
If you cannot find the required language on the first screen, move to the fol-
lowing screens by pressing the button .

Selected hydraulic scheme can be later changed with service parameter S1.1.
Controller RESET!
Disconnect the controller from the power supply.
Press and hold the button and switch on power supply.
The controller resets and goes to initial setup.
CAUTION!
By selecting ‘reset’ all previous controller settings are erased.
Next, you select a hydraulic scheme for the controller
function. Move between schemes by means of buttons
and .
Confirm the selected scheme by pressing the button.
STEP 2
After you selected the scheme, the controller requires
confirmation of the selection by pressing the button.
If you accidentally selected the wrong scheme, go back
to reset the scheme by pressing button .
