1

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

control of 3-speed 230V fans, automatically adjusting the 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 EFAN230 is a complete  

solution for anyone who wants to ensure thermal comfort in their home or office.

ENGO CONTROLS EFAN-230W WIFI 230V Fan Coil Thermostat User Guide Overview

Summary of Contents

• Page 1: LCD icons description and button description provide an overview of the device's functionality. The product complies with EU directives 2014/53/EU and 2011/65/EU. Safety information emphasizes using the device in accordance with national and EU regulations and only as intended. Installation must be performed by a qualified person following applicable standards and regulations. The controller is designed for fan coil units or trench heaters, suitable for both 2-pipe and 4-pipe systems. It offers flexible control of 3-speed 230V fans and includes frost protection and overheat protection functions. The built-in ECO mode helps save energy and reduce energy bills. The device supports mixed systems, including fan coil and underfloor heating. Technical data includes power supply specifications and temperature ranges for operation. Communication options include Wi-Fi 2.4 GHz and Modbus RS-485.
• 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. In a 2-pipe system, the system switches to cooling mode below a certain temperature and to heating mode above another value. 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 to exchange messages. The parameter determines the width of the temperature range in which the fan operates in heating mode. To reset the controller to factory settings, hold down the appropriate buttons. The fan will start operating if the room temperature rises above or drops below the set temperature by a specified value.
