FCA/S 1.1M Fan Coil Actuator Manual

This document describes the ABB i-bus® FCA/S 1.1M Fan Coil Actuator, which controls up to three fan speeds and operates electrothermal or electromotor valves for 2-, 3-, or 4-pipe heating and cooling systems. It features short-circuit-proof valve outputs, potential-free inputs for contact scanning (e.g., window contacts), and supports both manual operation and commissioning via the ABB i-bus® system.
