What is Fan Coil Unit (FCU) System?
Fan coil unit (FCU), also known as a vertical fan coil unit (VFC), is a device composed of a heat exchanger (coil) and a fan. As part of the HVAC system used in residential, commercial, and industrial buildings, fan coil units are usually connected to air ducts and thermostats to regulate the temperature of one or more spaces and to assist the main air handling unit for each space. The thermostat uses a control valve to control the fan speed and/or the flow of water to the heat exchanger.
Hotowell, as a professional thermostat provider for over 13 years, there are several thermostat solutions for FCU the system, the following will discuss three smart thermostat solutions.
1. Modbus Thermostat
Modbus is a data communications protocol originally published by Modicon in 1979 for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.
Hotowell Modbus thermostat is widely used in hotel central control system, our Modbus Communication is Via RS485, with stable quality. With Modbus communication control, you can connect most 32pcs thermostats in one loop. You can control many thermostats at the same time, it is especially suitable for the central control system.
2. WiFi Thermostats
As the speed development of the network, more and more Wifi control thermostats come out. After you install the Wifi thermostat in your home, you can control your home’s temperature from anywhere at any time. After your smartphone connects to the thermostat, you can turn on or off connected devices wherever you are at any time through any internet connection, which is much more intelligent and convenient.
All of Hotowell’s Wifi thermostats include Voice Control function, our thermostats easily work with Amazon Alexa, Google Assistant and related smart devices. You can connect our wifi thermostats through these smart devices in your home, then your home’s temperature can be controlled by voice hands-free.
3. BACnet Thermostat
BACnet is a communication protocol for Building Automation and Control (BAC) networks that leverage the ASHRAE, ANSI, and ISO 16484-5 standard protocol. BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control (HVAC), lighting control, access control, and fire detection systems and their associated equipment. The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform.
Hotowell’s BACnet thermostat HTW-31-F10 with two main choices, on/off valve control or modulating valve control. The BACnet thermostat is widely used in central control systems, which with similar functions to Modbus thermostat, you can control many thermostats at the same time with this kind of communication thermostat. Hotowell’s BACnet thermostat with stable quality and get pretty good feedback from our clients, welcome to contact me if there is any interest in our BACnet thermostats. Our engineers are happy to discuss some professional knowledge with you.
