Pos : 2 /156-Honeywell/Sicherheitshinweise/Sicherheitshinweise @ 0\mod_1207134414454_6.doc @ 9105 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 low- temperature 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 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. 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 draw- off points (kitchen, bathroom etc.) in the following cases. Add sufficient cold water in these cases. Automatic anti- When the automatic anti-legionella mechanism is activated, the legionella mechanism 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 / In the manual mode / emission measurement operating mode, the Emission hot water is heated up to the highest possible boiler temperature, measurement 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. EN2H-0220GE51 R0308 9 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.

Slow increase in outside temperature Deactivation is also initiated when the averaged and current outside temperature exceeds the set value. 54 EN2H-0220GE51 R0308 SDC / DHC Operation Undoing deactivation Deactivation is undone when the averaged and current outside temperature exceeds the set value by 1 K. The summer deactivation function is undone: • In case of an outside sensor defect • In case frost protection is active NOTE During deactivation phases (standby mode, manual summer operation, summer deactivation) lasting longer than 24 hours all pumps are switched on for approx. 20 s and the mixers are temporarily opened during this time to protect against blocking by corrosion. In connection with a second outside sensor, the current averaged outside temperature is accepted for summer deactivation if the average value of both sensors is specified during outside sensor assignment. Active summer deactivation is represented by a beach umbrella symbol in the basic display. Only active in the AUTOMATIC operating mode.

Factory setting ECO Setting range ECO, RED Set values RED (lowering operation) The heating circuit pump of the direct heating circuit continues functioning during reduced operation (see 4.2.3.2 Time program, pg. 52). The flow temperature is determined based on the lowered room temperature from the associated reduced heating curve. The set maximum temperature is not undershot. Application Building with minimal insulation values and high cooling loss. EN2H-0220GE51 R0308 57 Operation SDC / DHC ECO (switch-off operation) During reduced operation, the direct heating circuit is switched off completely with outside temperatures above the set frost- protection 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. Application Building with high insulation values (full heating protection). NOTE The mode set here also applies for the ABSENT and RED. HEATING operating modes.
