Dimplex LA 1118CP Air-to-Water Heat Pump
Quick Installation Guide
Page 1: Electrical Layout
This section details the electrical connections for the Dimplex LA 1118CP heat pump. It includes a diagram showing the main components such as the heat pump (+A100), heat pump manager (+A200), and electrical distribution (+A300). Key electrical elements like fuses (e.g., -F+A200, -F+A100), contactors (-K22), and wiring (e.g., NYM-J 3x1.5mm², J-Y(ST)Y..LG 4x0,28mm²) are illustrated.
Page 2: Hydraulic Diagram
This page presents the hydraulic schematic for the heat pump system. It illustrates the flow of water through various components, including pumps (e.g., M16, M13), valves (e.g., VTB), and heat exchangers. The diagram shows connections for heating circuits (HWW) and domestic hot water (WWM), with labels like R1, R2.2, R5, U1, U2, U9.
Page 3: Plug-in Connections
This section focuses on the plug-in connections and wiring details. It shows the heat circulating pump (-M13), auxiliary circulating pump (-M16), and remote fault indicator (-H5). The diagram details connections to the +A300 electrical distribution unit, including various terminals (X1.2, X2, X3.1, X3.2) and specific functions assigned to different colored terminals (e.g., grey for general, yellow for domestic hot water). It also shows connections for external wall sensors (-K23), demand sensors (-K22), and Smart-Grid inputs.
Page 4: Domestic Hot Water and Circulation
This page illustrates the electrical connections related to domestic hot water (DHW) and circulation. It shows the DHW pump (-M18), DHW circulation pump (-M24), and reversing valve for DHW (-YM18). The diagram details connections to the +A300 unit, including terminals for DHW sensors (-R3), DHW circulation (-B3), and DHW thermostat (-K31). It highlights the function assignment for DHW as '1 (yellow)'.
Page 5: Second Circuit Connections
This section details the electrical connections for the second circuit, which may involve a mixer or other components. It shows the mixer for the second circuit (-M22) and the pump for the second circuit (-M15). The diagram illustrates connections to the +A200-N1 unit, including terminals for the second circuit sensor (-R5). The function assignment for the second circuit is indicated as '2 (green)'.
Page 6: Bivalent Heat Generator Connections
This page covers the electrical connections for a bivalent heat generator and its associated mixer. It shows the bivalent heat generator (-E10.2) and the bivalent mixer (-M26). The diagram details connections to the +A200-N1 unit, including terminals for the bivalent heat generator and mixer. The function assignment for the bivalent operation is indicated as '3 (red)'.
