Section 1: PLC System Overview

Key Features:

• Uses dedicated control wiring over the existing electrical network for industrial-grade communication.
• Ideal for large or signal-restricted buildings with thick stone or concrete walls.
• Supports multi-zone precision management for consistent year-round comfort.

Advantages:

• High signal stability and reliability, minimal interference.
• Easily integrates with pump linkage and fixed supply water temperature logic for safe radiant cooling.
• Strong ROI for large-scale retrofit projects.

Limitations:

• Requires control line installation, slightly longer construction time.
• Higher cost for small-scale or partial retrofits.

Section 2: RF System Overview

Key Features:

• Operates via 868MHz wireless communication, no wiring required.
• Flexible thermostat placement, ideal for small-scale or partial retrofits.
• Supports zone control and automatic summer/winter mode switching.

Advantages:

• Quick and non-invasive installation, preserving historic structures.
• Easily expandable for future upgrades or additional zones.

Limitations:

• Signal may be affected by thick walls; proper placement is required.
• Large multi-zone projects may require additional signal repeaters.
