Build smarter fan coils with intelligent controls and wireless diagnostics

Avnan’s integrated fan coil platform combines advanced control electronics, wireless connectivity, and technician diagnostics to help HVAC OEMs build more capable, connected, and serviceable products.

Control Board + Power Board + Mobile Diagnostic App → Fan Coil System

One platform. Three advantages.

Advanced control

EC and PSC motor control, multi-valve systems and sensor inputs

Connected intelligence

BACnet, RS-485, Wi-Fi and BLE connectivity

Faster diagnostics

Real-time system data and technician troubleshooting through a mobile app

Fan coil systems are getting smarter. Service shouldn't get harder.

Traditional fan coil systems can require technicians to manually troubleshoot multiple components, operating conditions, and control signals.<

Avnan brings control and diagnostics together.

Our platform gives OEMs an integrated foundation for controlling the fan coil while providing technicians with real-time visibility into system performance.

Without integrated diagnostics

Fault → Manual testing → Guesswork → Longer service time

With Avnan’s Advanced Control Platform

Fault → Connect → See live data → Diagnose → Resolve

One platform. Complete fan coil control.

Control every part of the fan coil

Our fan coil main control board features Wi-Fi and wireless communication with integrated BACnet capabilities, making it an ideal solution for modern HVAC environments and versatile applications. In addition, it also provides options to control a multi-tap PSC motor and multi-valve actuators.

This capability allows for real-time monitoring and efficient interaction with other subsystems, providing streamlined operation and maximum energy savings.

EC Motor Control

PWM or 0–10 V control with speed monitoring.

PSC Motor Control

Support for multi-speed PSC motors.

Multi-Pipe Systems

Compatible with 2-, 3-, 4- and 6-pipe heating and cooling configurations.

Intelligent Valve Control

On/off or modulating actuator control.

Multi-Sensor Inputs

Temperature, relative humidity, indoor air quality, water leak and condensation overflow sensing.

Building Integration

RS-485 communication and BACnet compatibility for BMS integration.

These map directly to the existing technical specifications, but present them as capabilities the OEM gets, rather than as a list of specifications.

Diagnose problems before they become service headaches.

Wireless connectivity gives technicians direct visibility into fan coil operation, helping them identify problems faster and troubleshoot with actual system data.

Functions and Features

Fan coil operation demands precise control of airflow, temperature, and energy consumption, requiring advanced control circuit boards and temperature sensors to enable valve actuation and variable speed operation of the fan motor. Additional capabilities, like automatic fault detection and alerts make these units unique.

Key functions and features of a fan coil control unit:

  • Controls EC motors by PWM or analog voltage 0-10V, monitoring their speed
  • Controls multi-speed PSC motors
  • Works with 2, 3, 4, or 6-pipe systems for heating and cooling using on/off or modulating actuators
  • Multi-inputs for various sensors such as: temperature, relative humidity, Indoor Air Quality, water leak, condensation overflow
  • RS-485 Communication Port
  • Optional opto-isolator module for ECM control
  • BACnet for Building Management systems (BMS)
  • Compatible with most standard thermostats
  • BLE app for troubleshooting
