LoRa Wire-Free Fan Coil Group Control System Wireless HVAC Billing BMS Platform
1. Product Overview
The LoRa wire-free central air conditioning group control system adopts RF-LoRa dual-band integrated wireless communication technology, solving the pain points of traditional wired fan coil renovation such as wall grooving, cable laying, long construction period and high cost. The complete system includes split & integrated LoRa wireless thermostats, LoRa signal repeaters, NC302 central gateway and dedicated BMS-Ⅱ HVAC billing management software. No power or signal wiring required between control panel and fan coil, cutting total construction cost by 35%. The wireless signal delivers strong penetration through multi-layer walls for stable self-networking in hotels & offices. Support battery & 220V dual power supply, one panel links up to 6 fan coils for synchronous zone control of large halls. The gateway uploads data to local server & cloud simultaneously, matched with visual BMS software to realize full-building remote monitoring, timing zoning, individual energy billing & automatic fault alarm. Widely applied for new & energy retrofit HVAC projects of hotels, malls, hospitals and office buildings.

2 Six Core System Advantages
1 True Cable-Free, 35% Total Construction Cost Saving
No grooving or pre-buried power/signal cables needed between split panel and fan coil receiver, saving pipe, labor & wall repair expense. Greatly shorten renovation period, 35% lower total construction cost than traditional RS485 wired system.
2 RF-LoRa Dual Band, Stable Signal Through Walls
Long-range LoRa radio with strong penetration across multi-floor slabs & solid walls, no signal disconnection in complex partition of hotels & hospitals. Optional GW12 repeater to boost weak signal for far-end areas, 24h stable data transmission.
3 One-To-Many Synchronous Zone Control For Large Space
Single wireless thermostat links maximum 6 fan coils, meeting synchronous temperature demand of conference hall & lobby. Reduce equipment purchase quantity and simplify daily management.
4 Dual Power Options Fit New & Retrofit Projects
Two series available: 220V integrated/split models for new construction; battery split panels for old buildings without wall grooving permission. Only fan receiver needs 220V power, no internal wall wiring required.
5 Local + Cloud Dual Remote Access, Multi-Terminal Support
NC302 gateway upload data to local server & Alibaba Cloud via Ethernet. Users log in via 4G mobile, tablet or PC Web to adjust temp, lock mode & check energy/fault without on-site staff.
6 Professional HVAC BMS, No Secondary Programming
BMS-Ⅱ exclusive terminal management platform, different from general configuration software. No coding required, only menu setup to launch. Support individual billing, energy-saving timing & multi-level authority, easy operation for property staff without industrial control expertise.
3 Standard 3-Tier System Topology
Terminal Layer: FC series LoRa thermostats collect room temp & control fan/valve, upload data wireless to gateway/repeater;
Transmission Layer: Optional GW12 repeater + NC302 central gateway aggregate all wireless signals, upload via TCP/IP Ethernet;
Management Layer: Local server or cloud platform runs BMS-Ⅱ billing software for remote monitoring via mobile & PC.
4 Two Standard Installation Schemes
Scheme 1 Integrated FC100L (New Construction)
Thermostat panel embedded into standard 86 box with 220V pre-wiring, built-in LoRa module. Fan coil wired to gateway, suitable for newly built commercial buildings with pre-buried pipelines.
Scheme 2 Split FC109L / FC219L (Renovation)
LoRa receiver installed beside fan coil with 220V power supply; only wireless panel mounted on wall, battery version requires no internal wiring. No wall damage needed, single room installation & commissioning finished within one day.
5 Main Application Scenarios
Renovation Projects: Aging star hotels, old office & mall HVAC energy upgrade, wall grooving prohibited;
New Commercial Buildings: High-end hotels, exhibition centers, shopping malls, grade-A hospitals, university teaching buildings; 3 Industrial Supporting: Industrial park offices, staff apartments, R&D labs with individual billing requirement; 4 Large Open Areas: Banquet halls, conference rooms, lobbies requiring one-to-many synchronous temperature control.
6 Operation & Management Value
1 Energy Saving: Set unattended low temp via background batch schedule to eliminate idle air conditioning waste, 15%-30% total power reduction; 2 Individual Billing: Auto statistics of room air conditioner runtime, solve charge sharing conflict for apartments & hotels; 3 Labor Reduction: Remote fault pop-up alert without floor-by-floor inspection, cut on-site maintenance manpower; 4 Flexible Expansion: Add new rooms only with extra wireless thermostat, no original bus wiring modification for quick capacity expansion.
