2Safety instructions

2.1Intended 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.

2.2Requirements 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.

NOTE 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.
