Access to the technician / OEM area
Entering a technician or OEM code enables additional setting options in the parameter menu. The technician code is: 1234. For access to the OEM area, please ask your field-service contact partner. Procedure: Press the and buttons simultaneously. The first number of the 4-digit code flashes. Set the first code number by turning the input button. Press the input button. The second number flashes. Enter all remaining code numbers as described in Steps 2 and 3. After entering the last code number, the controller is enabled for the respective area (technician or OEM). Press and hold the rotary button longer than 3 seconds. You reach the menu-selection level and can enter / modify parameters. Pressing the button jumps back to the previous selection.
Pressing the button, pressing and holding the input button longer than 3 seconds or waiting until the set info time expires causes a jump back to the basic display.

Safety instructions

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.
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 lowtemperature boilers.
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.
Connection conditions All electrical connection work may only be carried out by qualified personnel!

Cable cross-sections 1.5 mm2 for all cables carrying 230 V (power supply, burner, pumps, actuator). 0.6 mm2 for bus cables (recommended type J-Y(St)Y 2 x 0.6). 0.5 mm2 for sensors, selectors and analog signal cables.
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).
Cable installation Install cables for sensors apart from the cables carrying 230 V! Branch boxes in the sensor cable must be avoided!
Grounding and zeroing Local regulations on the connection of equipment must be observed!
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 antilegionella 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. 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.
Manual mode / Emission measurement

Installation

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.

Maintenance and cleaning The controller is maintenance-free. The device can be cleaned externally with a moist (not wet) cloth.

In the state of delivery, each controller type covers multiple hydraulic units. Each hydraulic unit can be changed or expanded by changing and/or adding parameters. A hydraulic unit is selected with parameter 01 in the "Hydraulics" menu. The corresponding inputs and outputs are assigned automatically based on the hydraulics schematic. This function simplifies the setting of a documented hydraulic unit considerably. Additional applications can be covered by setting the individual parameters. Where necessary, the parameters are also specified in these mounting instructions. A description of how to access parameter settings can be found in the parameter list.
