Automatic fan speed controller | dual output 6 A | Wi-Fi gateway
Product description
The TCMF8-602WF is an advanced controller for precise AC fan speed control in single-phase systems. It operates on 230 VAC / 50-60 Hz with a maximum load of 2 x 6 A.
It automatically adjusts fan speed based on real-time sensor data, with an RGB LED for status indication. The controller offers both kick start and soft start functions, along with adjustable minimum and maximum motor voltage settings.
For connectivity, it receives data from up to four HVAC sensors via RJ45 connectors with Power over Modbus (PoM), using the Modbus RTU (RS485) protocol. It has a built-in sensor power supply and two separate TK inputs for motor thermal protection.
This model includes a built-in Wi-Fi internet gateway. Firmware can be downloaded from SenteraWeb, and you can choose to keep the gateway connected or not.
The device has an IP54 protection rating and a 2-year warranty.
Additional specifications and description
How Do TCMF8 Controllers Work, and What are Their Connectivity Options?
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 has an integrated internet gateway that can be connected via Wi-Fi. Once the firmware is downloaded the TCMF8 controller can work standalone 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 on-demand control of AC fans and offers specific solutions depending on the customer’s needs.
Where Can I Find and Utilize Application-Specific Firmware?
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. The fan speed can be set via the knob on the front panel. 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?
This fan speed controller can be installed on a wall or panel indoors. Make sure that the fan speed controller can cool sufficiently. Preferably install it in a cool place, best not in direct sunlight. The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is flame extinguishing, very tough and offers good protection against impacts. It offers an IP54 protection against ingress dust and water.
