Final answer:
A Closed loop control system is best suited for controlling multiple indoor coils due to its use of feedback to adjust each coil individually, allowing for precise regulation.
Step-by-step explanation:
The type of control system that can more easily control multiple indoor coils is a Closed loop control system. Closed loop systems, also known as feedback control systems, utilize a method of control where the system's output influences the control action.
This allows for precise regulation and adjustment of the system's performance. For managing multiple indoor coils, such as those in an HVAC system, the feedback provided can be used to adjust each coil individually and maintain desired conditions across different zones or rooms. In contrast, open loop and feedforward systems do not utilize such feedback, which makes them less adaptive to changes and, therefore, less suitable for this complex task.
