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.
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 lowtemperature boilers.
EN2H-0220GE51 R0308 7
Safety instructions SDC / DHC
2.2.1 Power supply
Do not disconnect the controller from the mains supply!
The battery for saving all individualised data is otherwise
unnecessarily strained. The frost-protection function of the
controller is deactivated.
2.2.2 Connection conditions
All electrical connection work may only be carried out by qualified
personnel!
2.2.3 Cable cross-sections
2
1.5 mm
for all cables carrying 230 V (power supply, burner,
pumps, actuator).
2
0.6 mm
0.5 mm
for bus cables (recommended type J-Y(St)Y 2 x 0.6)
2
for sensors, selectors and analog signal cables.
2.2.4 Maximum cable lengths
Sensor, selector and analog inputs
We recommend using cables no longer than 200 m. Longer
connection lines could be used, but increase the risk of
interference.
Relay outputs
Unlimited cable length.
Bus connections
Max. length of 100 m from the first bus subscriber to the last one
(incl. wall modules).
2.2.5 Cable installation
Install cables for sensors apart from the cables carrying 230 V!
Branch boxes in the sensor cable must be avoided!
8 EN2H-0220GE51 R0308
SDC / DHC Safety instructions
/
2.2.6 Grounding and zeroing
Local regulations on the connection of equipment must be
observed!
2.3 Hot-water temperature greater than 60 °C
ATTENTION
Note that there is a danger of scalding at all hot-water drawoff points (kitchen, bathroom etc.) in the following cases.
Add sufficient cold water in these cases.
Automatic anti-
legionella mechanism
When the automatic anti-legionella mechanism is activated, the
hot water is automatically heated to the anti-legionella
temperature (65 °C at the factory) on the selected day and at the
selected time to kill any legionella bacteria found in the hot-water
tank.
Manual mode
Emission
measurement
In the manual mode / emission measurement operating mode, the
hot water is heated up to the highest possible boiler temperature,
as the burner and all pumps are switched on and the mixer is
opened fully. There is an acute danger of scalding at all
connected hot-water draw-off points! Add sufficient cold water or
switch off the hot-water loading pump (at the switch of the pump,
if present). Heating and hot water are in unregulated continuous
operation. This operating mode is for special use by the chimney
sweep for emission measurement or if the controller is defective.
The high hot-water temperatures can be prevented, however, by
setting the boiler thermostat to a max. boiler temperature of
approx. 60 °C.

Safety instructions SDC / DHC
2.4 Connection of accessory parts
WARNING
According to VDE 0730, a separator for each mains terminal
is to be provided in the voltage supply to the control
equipment. Observe the local regulations regarding
grounding and zeroing.
As soon as the mains voltage is applied to terminals 21, 22,
2, 6, 12 and 18, headers X3 and X4 can also carry mains
voltage.
If the heating circuit and hot-water loading pumps do not
have an On / Off switch, but manual switch-on and switch-off
capability is still desired, the appropriate switches must be
installed by the customer. All accessory parts (sensors,
selectors etc.) are to be connected to the respective circuit
diagram.
2.5 Maintenance and cleaning
The controller is maintenance-free. The device can be cleaned
externally with a moist (not wet) cloth.

recurring assignments with different assignment times (e.g. shift
work). Max. three heating cycles, each with a switch-on and
switch-off time, are available for each day of the week for
programming switching times. Each heating cycle can also be
combined with a freely-selectable temperature specification.
NOTE
The default programs are not lost when overwritten by individually
created programs. Individualised programs, however, are deleted
when default programs are reloaded and must be recreated. For
this reason, individualised switch-on / switch-off times and
temperature specifications should always be entered in the tables

Copying heating circuits
NOTE
Heating circuits cannot be copied to hot-water circuits since they
have different cycle temperatures: If a heating circuit is selected
as the source circuit, the hot-water circuit can no longer be called
up as the target circuit. The hot-water circuit as the source circuit
is also the target circuit. In this case, only programs of the hotwater circuit are copied among one another if they were enabled
in the "System Parameter" menu.

The heating circuit pump of the direct heating circuit continues

Operation SDC / DHC
ECO (switch-off operation)
During reduced operation, the direct heating circuit is switched off
completely with outside temperatures above the set frostprotection limit. The maximum heat generator temperature is not
functional. The heating circuit pump is switched off after a delay to
avoid safety deactivation by reheating the heat generator (pump
follow-up).
If the outside temperature is or becomes lower than the specified
outside temperature frost-protection limit, the controller switches
from deactivated (deactivation mode) to lowered lowering
operation and controls the heating circuit temperature based on
the set lowering curve taking the set minimum heat generator
specification into account.

4.2.5.2 Heating system
This parameter refers to the type of the heating system (floor,
radiator or convector heating) and can be matched to the
exponent of the respective heat distributor. Using its progressive
characteristics, the set value determines the curve characteristics
of the heating curve of the direct heating circuit and compensates
for the losses in output in the low-temperature range with it.
The following settings are recommend depending on the type of
heating system:
1,1 Slightly progressive heating curves for floor or other
area heating.
1,3 Progressive standard heating curves for all radiator
heating with m-values between 1.25 and 1.35.
2 Progressive heating curves for convector and
baseboard heating.
>3 Heavily progressive heating curves for general ventilator
applications with high starting temperatures.

The error messages appear in continuous alteration with the basic
display. Multiple errors that occur at the same time appear one
after another in the order in which they occurred. The following
types of error message exist:
Sensor measured values that do not lie in the measurement
range are evaluated as an interruption or short-circuit. They
appear depending on the type and allocation with fault code 10 to
20 and index 0 for short-circuit or 1 for interruption.
These error messages evaluate the respective switching status.
They appear depending on the type and allocation with fault code
30 to 40 and index 0, 1 or 2.
These error messages evaluate the control result to be expected.
They appear depending on the type and allocation with fault code
50 to 60 and index 0, 1 or 2.
These error messages refer to address faults such as double
issuance or non-recognition of address settings on the data bus.
They appear with fault code 70 and index 0 or 1, depending on
the type and assignment.
