SDC / DHC 43 Safety Instructions
EN2H-0220 GE51 R1005 4
2 Safety Instructions
2.1 Application
The Smile controller family DHC/SDC is designed
exclusively for the control of warm water heating and
district heating systems including domestic hot water
control. These systems should not exceed a flow
temperature of 120 °C.
2.2 Conditions for start-up
CAUTION The heating installation must be completed and filled with
water in order to prevent the pumps from running dry and
to avoid damage for the boiler.
The control system must be installed according to the
mounting instructions.
All electrical connections (power supply, burner, valve
actuator, pumps and sensors) must be carried out
according to the local rules and standards and must
comply with the attached wiring diagrams.
If a floor heating system is connected, a limiting
thermostat must switch off the pump if the flow
temperatures are too high.
The heating specialist must check the complete
installation before switching on the controller.
IMPORTANT NOTE! The actual time and date are already adjusted from the
factory and backed up by a battery.
There is a basic time program already activated and the
control functions for standard heating systems with low
temperature boilers are pre-adjusted.

2.3 Do not separate the controller from the mains
If this happens, the back-up battery will be unnecessarily
stressed. In addition, the frost protection functions of the
controller will be out of order.
2.4 Electric installation
Qualified personnel must carry out all electrical
connections.
2.5 Cable dimensions
1.5 mm² for all 230 V cable (power supply, burner,
pumps, actuators).
0.5 mm² for sensors, selectors, bus and analogue in- and
outputs.
2.6 Maximum cable length
Sensors selectors and analogue inputs
A maximum cable length of 200 meters is recommended.
Longer distances are possible but increase the risk of
interferences.
Relay outputs
Unlimited cable length.
Bus connections
A maximum cable length of 100 meters is strongly
recommended.
2.7 Cable installation
Cables for 230 V must be installed separate from low
voltage (sensor selector bus) cables.

EN2H-0220 GE51 R1005 6
2.8 Cabinet earth and ground
Please install and connect the controllers according to
local rules and standards!
2.9 Domestic hot water higher than 60 °C
WARNING Please note that in the following cases there is a danger
at hot water tabs (kitchen, bath). In order to avoid
scalding please mix enough cold water.
Anti legionella automatic
If the anti legionella automatic is activated, the domestic
hot water will automatically be heated up to temperatures
around 65 °C order to kill legionella bacteria in the hot
water system.
Manual operation / Emission measurement
In the manual mode / emission measurement mode the
domestic hot water can be heated up to the maximum
possible boiler temperature because the burner and all
pumps are switched on and the valves will be completely
opened. In addition, here there is the danger of scalding
at all warm water tabs in the building. Please mix enough
cold water or switch the domestic hot water loading
pump manually off (if there is a switch at the pump).
Heating and domestic hot water are not temperature
controlled in these modes. These modes are especially
used by the emission measurement specialist or by the
installer in case the controller is defect. The high water
temperatures can however be avoided if the boiler
thermostat is adjusted to a max. of 60 °C.
2.10 Connecting accessories
CAUTION According to VDE 0730 the power supply for the
controller must have a separate main switch for life and
neutral. Please follow local rules and standards for
cabinet earth and ground!
As soon as there is power supply at the terminals 21, 22,
2, 6, 12 and 18, also the terminal rows X3 and X4 will
carry 230 V connections!

External switches must be installed if a manual switch
function is desired for pumps. All accessories (sensors,
selectors, etc.) must be connected according to the
attached wiring.
2.11 Service and cleaning
The controller is service free. The unit can be cleaned
with a moist cloth from the outside.
