INTRODUCTION
Differential controllers SGC16H 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
SGC16H 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

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

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 scheme 203.
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 only by scheme 201 and 203.
Holiday mode is used in cases of longer absence from home when there is no consump-
tion of hot water for longer period (several days).
Pump is activated if temperature of collectors T1 reaches P2.2 value and stays ON until
the temperature of collectors drops below the P2.2 plus hysteresis (P1.18) or until the tem-
perature of tank T2 reaches the P2.4 value. In the night time (but also in the day time),
when the collector temperature T1 drops 20 K below tank temperature T2, the pump is
activated again to cool the tank by circulating the liquid between hot tank and colder collec-
tors. The cooling process is active until the tank temperature T2 drops to P2.4 value or until
the temperature difference T2 - T1 is less than 15K.
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.
Each function can be at anytime cancelled by selecting icon .
Setting of PROTECTION OF MAX. COLLECTORS TEMPERATURE (S2.1)
and RECOOLING OF STORAGE TANK (S2.7) have no influence on Holi-
day mode operation.
The 20 K and 15 K temperature differences apply only if you do not change
the original factory setting. Generally, T cooling ON = P1.1+10 K and
T cooling OFF = P1.2+10 K.
