Automatic fan speed controller | Dual motor output 6 A
Product description
The TCMF8-602DM is a modern controller for precise AC fan speed control in single-phase systems. It runs on 230 VAC / 50-60 Hz power with a maximum load of 2 x 6 A.
The device automatically adjusts fan speed based on real-time sensor data and features an RGB LED status indicator. It offers both kick start and soft start functions, along with adjustable min/max motor voltage settings.
It can operate as a standalone unit or connect to the cloud via an optional Sentera gateway.
For smart automation, it receives data from up to four HVAC sensors using Power over Modbus (PoM) via RJ45 connectors, and it uses the Modbus RTU (RS485) protocol. It also includes a built-in sensor power supply and two separate TK inputs for motor thermal protection.
The device has an IP54 protection rating and a 2-year warranty.
Additional specifications and description
How Do TCMF8 Controllers Work, and Do They Require an Internet Connection?
TCMF8 controllers require application specific firmware. Typically, they regulate fan speed based on the input of the connected sensors or potentiometers. Application specific firmware can be downloaded via SenteraWeb - your personal HVAC cloud platform. This controller does not have an integrated internet gateway. An external internet gateway is required to connect to SenteraWeb and to download application specific firmware. Once the firmware is downloaded, the TCMF8 controller can work stand alone or it can stay connected to SenteraWeb.What Are AC Fans, and How Does the TCMF8 Control Them?
An AC fan is a fan powered by alternating current. It plays a crucial role in facilitating the circulation of air within heating, ventilation and air conditioning systems. AC fans are commonly used in various cooling applications to dissipate heat generated by electronic components or to enhance air circulation in buildings. The TCMF8 is intended for control of AC fans and offers specific solutions depending on the customer’s needs.
Where Can I Find and Utilize Application-Specific Firmware?
We offer a limited number of specific firmware versions for typical HVAC applications (e.g. destratification, demand based fan speed control, etc.). First select the required functionality via our website's solution page, then download the application specific firmware. If necessary, it is possible to adjust some settings via the Modbus Holding registers. No programming is required!
What Types of Fans Does the Controller Support, and How Does It Operate?
This controller has two outputs to control AC fans with single-phase motor. The maximum combined current is 6 A per output. Fan speed is regulated by reducing motor voltage via phase angle control / TRIAC technology. This means that this speed controller is only suitable for voltage controllable motors. If you are not sure whether your motor is voltage controllable, it is best to contact the motor manufacturer. This speed controller works completely silently. Thanks to the accurate motor control, humming motor noise at low speed remains limited.
How Does the Controller Prevent Motor Overheating?
When an AC motor fails, it is often due to overheating. In order to detect motor overheating in time, some motors are equipped with TK or thermal contacts. These thermal contacts measure temperature in the motor windings. TCMF8 fan speed controllers can monitor two thermal motor contacts. In case of motor overheating, the TK monitoring function will disable the motor to prevent permanent motor damage. The motor TK can be connected to the TK and 24 VDC terminals.

How Are External Sensors Connected, and What is PoM?
External HVAC sensors or potentiometers can be connected via Modbus RTU communication or via the analogue inputs. To simplify wiring of the external devices, 24 Volt supply is available via the RJ45 socket. The 24 Volt supply and Modbus communication can be distributed via one cable - we call it Power over Modbus or PoM. All settings can be adjusted via the Modbus Holding registers.
Where and How Should the Controller Be Mounted?
The enclosure of the TCMF8 is designed for indoor use and can be installed on a wall or panel. It is important to ensure that the location where it is installed allows for sufficient cooling to prevent overheating. This helps maintain optimal operating conditions and prolongs the life of the controller.
The enclosure of the TCMF8 is constructed from high-quality r-ABS VO (UL94) plastic and, what is more, it is manufactured in our own factory. The type of plastic used is known for its flame-extinguishing properties, toughness, and resistance to impacts. The enclosure offers an IP54 protection rating.
