Comparing with floor heating, the fan coil system is essentially a completely watery system. Fan Coil Unit includes a fan and a coil which are used for heating and cooling and these units need a thermostat to be controlled. If there is a single coil in the fan coil used, the system is called 2 pipes fan coil system.  Two pipes circulate in the system making distribution and collection. A distribution pipe and a collection pipe are connected to each fan coil unit. In this case, either cold water or hot water can be circulated throughout the system.   If there are two separate pipes as heating and cooling in the fan coil, the installed system is called a four-pipe fan coil system. Four pipes circulate in the system, making two distributions and two collecting. Two distribution pipes and two collector pipes are connected to each fan coil unit. Cold water circulates independently in one of the pipe pairs and hot water in the other. Therefore, heating and cooling can be done simultaneously in each fan coil unit independently of each other. Compared to the 2 pipes, the 4 pipes are more complex but easier for the water management.Since fan coil systems operate in heating and cooling, it is required to perform heating or cooling in summer or winter periods. In this case, we will normally introduce the  change-over sensor which is used to detect water temperature (to judge winter or summer). In General situation, heating or cooling mode selection can be made manually. When heating mode selected; If the room temperature falls below the set temperature, the fan coil is activated and tries to heat the environment. In cooling mode, if the room temperature rises above the set temperature, the fan coil is activated and tries to cool the environment.Where are the fan coil thermostats installed?Fan coil systems used in commercial buildings such as hospitals, hotels, shopping malls and business centers operate in two types. These systems, called 2-pipe and 4-pipe, directly affect the comfort and energy savings of the users.Based on different applications, Modbus/Bacnet/KNX protocol based fan coil thermostat is needed for different installations.

Fan coil thermostats are a type of thermostat that are specifically designed to control the temperature in fan coil units, which are commonly used in commercial and multi-unit residential buildings. A fan coil unit is a heating and cooling device that consists of a fan and a coil, and is typically installed in a wall or ceiling. The fan is used to circulate air through the building, and the coil is used to heat or cool the air as it passes through. A fan coil thermostat is typically installed near the fan coil unit and is connected to it through a series of wires. It is used to control the operation of the fan and the coil, and to adjust the temperature in the room. Some fan coil thermostats are simple and only allow for manual adjustments, while others are more advanced and have programmable scheduling and remote access capabilities. Fan coil thermostats are widely used in commercial buildings such as office buildings, hotels, and apartment buildings because they offer precise temperature control and energy savings. They are also easy to install and maintain. At E-Top controls, we mainly produce following fan coil thermostats:   1. Digital Fan Coil Thermostat without LCD display as FT-03, it is 2 pipe system with 3 fan speed control only  2. Digital LCD Display FCU Thermostat as FT-06; It can be 2 or 4 pipe with 3 fan speed control, keycard, Modbus, remote sensor also available   3.   Touch Programmable FCU HVAC Rom Thermostat as FT-09. Compare with above basic model, this type design is more modern, fashionable, and intuitive. What’s more, Bacnet, Modbus, Zigbee or WiFi communication protocol is also available. 4.   4.3inch Color Touch Intelligent Smart FCU Thermostat as FT-CS03. Keep the same function as FT-09, such Luxury 4.3inch capacitive touch screen with glass design make it a top thermostat. Customized user interface is welcomed.
