Controller for fan coil units or trench heaters with fan, ideal for both 2-pipe and 4-pipe systems. The  

unit offers flexible 0..10V control of fans and valves, automatically adjusting fan speed as required.  

Frost protection mode and overheat protection functions guarantee safety, while the built-in ECO  

mode saves energy, resulting in lower energy bills. With support for mixed systems (fan coil and  

underfloor heating), the EFAN24 is a complete solution for anyone who wants to ensure thermal  

comfort in their home or office.

ENGO CONTROLS FAN-24W 24V Fan Coil Thermostat User Guide Overview

Summary of Contents

• Page 1: LCD icons description and button description are provided. This product complies with EU directives 2014/53/EU and 2011/65/EU. Safety information emphasizes use in accordance with national and EU regulations. Installation must be performed by a qualified person in accordance with standards. The controller is designed for fan coil units or trench heaters with flexible control. Frost protection mode and overheat protection functions ensure safety. The unit supports mixed systems, including fan coil and underfloor heating. Technical data includes power supply specifications and communication standards. Compatibility with the ENGO Smart application is noted. Easy installation and configuration are highlighted.
• Page 2: Installation of the Wi-Fi thermostat in the app requires ensuring your router is within range and that you are connected to the Internet. To enter installer parameters, press and hold the button for 3 seconds. The hysteresis value for the cooling valve is adjustable between 0.1°C and 2°C. Download the ENGO Smart app from Google Play or Apple App Store. To register a new account, follow the steps provided in the app. After installing the app and creating an account, connect the thermostat to Wi-Fi. The MODBUS RTU structure uses a master-slave system for communication. To reset the controller to factory settings, hold down the buttons until the FA message appears. The fan will start operating if the room temperature drops below the set temperature by the specified value. The thermostat can be configured for both heating and cooling modes based on temperature readings.
