INTRODUCTION
Differential controllers SGC are modern designed, microprocessor-driven devices made
with digital and SMT technology.
These devices are intended for regulating domestic hot water warming by means of solar
collectors or for regulating domestic hot water warming by means solid fuel boiler, electric
heater or other energy resources.

INITIAL CONTROLLER SETUP
SGC 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 is 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
confirmation 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 set-
up.
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 .

SYMBOLS FOR NOTICE AND WARNINGS
Symbol Description
Notice
In case of exceeding the maximum temperature or activation of pro-
tection function, the controller indicates the event with flashing symbol
on the display. If the maximum temperature is no longer exceeded or if
the protection function is turned off, a lited symbol indicates a recent
event.
Press to open the screen to check notifications.
Warning
In the event of sensor failure, pump error or flow sensor error, the
controller indicates the failure with flashing symbol on the display. If
the issue is resolved or no longer present, a lited symbol indicates a
recent event.

USER FUNCTIONS
User functions enable additional comfort and benefits when using the controller. In menu,
the following user functions are available:
One-time domestic hot water warming
One-time d. h. w. warming is possible only by schemes with a liquid fuel
boiler, heat pump or electric heater.
Use this function when you want to immediately turn on the d. h. w. warming.
By pressing buttons and select function and activate it by pressing the but-
ton .
You leave settings by pressing the button .
Holiday mode
Holiday mode is enabled in schemes with solar collectors, liquid fuel boiler,
heat pump or electric heater.
Holiday mode activates cooling down of the storage tank during night time to minimum
temperature (P2.3). Cooling is carried out through solar collectors. This way we enable the
solar system to operate normally the next day for as long time as possible.
Holiday mode is activated until selected date. After you have activated the Holiday mode,
choose the Holiday mode icon again. A new screen is displayed, where you can set the
date when the Holiday mode should be cancelled.
Function switch-off
You can deactivate a currently active function at any time by selecting the icon with
buttons and , and confirming it with the button.

OPERATION MODE SELECTION
In group “OPERATION MODE” select the required controller operation mode. You can select
between automatic mode, controller switch-off and manual mode.
Description of operation mode:
You choose the required mode by pressing buttons , and confirm it by press-
ing button .
You exit the setting by pressing button .
Manual mode
This mode is used for testing the heating system or in case of a malfunction.
Every output can be manually activated or deactivated.
By pressing buttons and ,
move through move among individual out-
puts R1-R6*. Select the output of which
state you want to change by pressing the
button. Values ON, OFF, AUTO or pump
RPM 40 %, 55%, 70 % and 85 % will begin
to flash. Now you can change the output
status with buttons and .
Confirm the selection by pressing the
button.
Exit the setting by pressing the button.
Controller switch-off
Controller is not performing system control and switches off all outputs.
All temperatures are still measured and shown. Protection functions are still
active and able to switch on output.
Automatic operation
Heating is active.
In the automatic operation mode, the controller enables activation and deacti-
vation of additional energy sources (for example: oil boiler, heat pump, electric
heater, etc.).
To activate or deactivate additional sources, select the icon again,
when the automatic operation mode has already been selected. A new screen
with additional sources will appear, where you can move through sources with
buttons and . By pressing the button,
select the source you wish to activate or deactivate. Symbol or will
begin to flash. You can change the source status with buttons and .
Exit the setting by pressing the button.
