Pos: 2 /156-Honeywell/Sicherheitshinweise/Sicherheitshinweise @ 0\mod_1207134414454_6.doc @ 9105 2 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.
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...
SDC / DHC Safety instructions 2.2.6 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 draw- off points (kitchen, bathroom etc.) in the following cases.
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. Pos: 3 /156-Honeywell/Bedienung/Uebersicht @ 1\mod_1207643459088_6.doc @ 9180 EN2H-0220GE51 R0308...
