FCT series fan coil thermostats for fan coil unit systems

FCT Series Fan Coil Thermostats

Engineered for surface-mounted FCUs with on-unit body integration, and fully equipped for energy metering and sub-billing via dual LoRaWAN and RS485 connectivity. One product family, two powerful solutions.

Product Lineup

A complete thermostat portfolio for surface-mounted FCUs — covering every control logic from traditional On/Off to 0-10V modulating, EC fan, and BMS-native connectivity. All models share a unified on-unit mounting design for seamless OEM integration, with select models supporting LoRaWAN and RS485 for energy metering applications.

Selection Guide

Select the optimal thermostat for your surface-mounted FCU by comparing control logic, fan type, valve actuation, and connectivity requirements — all within a unified on-unit form factor.
Comparison of different fan coil thermostat control logic for fan coil units
Dimension EC Fan + On/Off Valve EC Fan + Modulating Valve AC Fan + On/Off Valve AC Fan + Modulating Valve
Fan Control Stepless (0-10V) Stepless (0-10V) 3-Speed (220VAC) 3-Speed (220VAC)
Valve Control On/Off (220VAC) Modulating (0-10V) On/Off (220VAC) Modulating (0-10V)
Control Precision Medium (air precise, water coarse) High (both air and water precise) Basic (stepped air, on/off water) Medium (stepped air, water precise)
Max Load Current 6A 3A 10A 6A
Energy Efficiency Excellent (EC saves, but valve loss) Best (EC + modulating, highest system efficiency) Moderate (AC fan less efficient) Good (AC moderate, but valve optimizes)
Recommended Scenarios Boutique hotels, high-end apartments (stepless air, moderate water) 5-star hotels, Class A offices (ultra comfort and saving) Retrofit, budget hotels (high load, cost-first) Hospitals, schools (precise water, traditional system)
VWF/VPF Compatibility Limited (On/Off not for continuous) Fully compatible (modulating ideal) Not recommended Compatible (valve adjustable, fan fixed)
Cost Positioning Mid-high (EC cost) High (EC + modulating, most expensive) Budget (AC mature) Mid (AC fan, but modulating adds cost)
Installation Ease Fairly easy (existing valve, but EC signal) More complex (0-10V wiring and valve match) Simplest (traditional wiring) Moderate (0-10V valve, fan unchanged)
Metering-Ready Depends on model Depends on model Depends on model Depends on model

Pro Tip: How to Optimize Your Selection

Choose EC + Modulating Valve for premium projects prioritizing energy efficiency and comfort. Choose AC + On/Off for cost-sensitive retrofits with high-load requirements. For energy metering and sub-billing applications, select models with LoRaWAN or RS485 connectivity.
