Terminal L(1) / N(2) / (3): Power Supply Input
• Dx-coil controller should be connected to the main power supply by means of a switch with a contact separation of at
least 3 mm. If the outdoor unit is a VRF model, connect it to L(1) / N(2).
Terminal Uv(U1) / Uv(U2): Communication line (Dx-coil controller and outdoor units)
• Details regarding the wiring can be found in the Installation Manual of the VRF outdoor unit.
Terminal AB / AB: Remote controller Wiring
• At these terminals an optional wired remote controller can be attached.
(Useful for installation, maintenance and Group control)
