2 Safety 
instructions 
2.1 Intended 
use 
The SDC / DHC Smile family of controllers was designed for the 
sole purpose of regulating and controlling hot-water, heating and 
district heating systems (including hot-water production) that do 
not exceed a maximum flow temperature of 120 °C. 
 
2.2  Requirements for start-up 
 ATTENTION 
The heating system must be complete and filled with water 
so that the pumps do not run dry and the heating boiler is not 
damaged. 
The control equipment must be installed in accordance with 
the installation instructions. 
All electrical connections (voltage supply, burner, mixer 
motor, pumps, sensor wiring etc.) must be carried out by the 
technician in accordance with the applicable VDE regulations 
and correspond with the circuit diagrams. 
If floor heating is connected, a limiting thermostat must also 
be installed in the flow line after the heating circuit pump. 
This switches off the pumps at excessive flow temperatures. 
Before starting up the controller, have the heating technician 
check all requirements listed above. 
 
The current time and date are already set at the factory and are 
backed up by a battery.  
 
The time switch functions based on a basic program and the 
control functions are preset for common heating systems with low-
temperature boilers.
