This documentation is valid for software version V 3.1 of your

control device. The software version is displayed after switch-on

for approx. 8 s. If you are using an older software version, please

contact your heating technician.

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.

NOTE

Safety instructions SDC / DHC

8 EN2H-0220GE51 R1111

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

1.5 mm2for all cables carrying 230 V (power supply, burner,

pumps, actuator).

0.6 mm2for bus cables (recommended type J-Y(St)Y 2 x 0.6)

0.5 mm2for 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!

SDC / DHC Safety instructions

EN2H-0220GE51 R1111 9

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 draw-

off points (kitchen, bathroom etc.) in the following cases.

Add sufficient cold water in these cases.

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.

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.

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.
