Product description

The TCMF8-602WF is an advanced controller designed for precise fan speed regulation in single-phase AC fan systems. The maximum motor current of 6 A per motor output (2 x 6 A) guarantees optimal efficiency for your HVAC configuration. The TCMF8-602WF dynamically adjusts fan speed by reading real-time data from up to 4 connected HVAC sensors via the RJ45 socket, supporting Power over Modbus. The capabilities can be expanded by effortlessly integrating additional sensors using extra power supply units.

The 2 analogue inputs, 2 analogue outputs and 2 tacho inputs provide a versatile toolkit for customization tailored to your HVAC requirements. Accessing application-specific firmware is a done through SenteraWeb, your dedicated HVAC cloud platform. The TCMF8-602WF comes equipped with an integrated internet Wi-Fi gateway for connectivity to SenteraWeb. You can choose between standalone operation or continuous cloud connectivity, granting you the freedom to control and monitor your HVAC system according to your preferences.

The TCMF8-602WF offers numerous functionalities. Sentera has developed a selection of firmware catering to various HVAC applications, including destratification, demand-based fan speed control, air handling unit control and more. The configuration process is facilitated by selecting your desired functionality on our website solution page and downloading the corresponding firmware from SenteraWeb. No programming skills are necessary for this user-friendly controller. Settings can be done through Modbus Holding registers, if needed.

Additional specifications and description

Application specific firmware
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.

Control AC fans
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. 
Different functionalitiesDrawing of ceiling fans, plastic box 
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!
Two motor outputs to regulate fan speed
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.
Thermal motor protection
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. 
Connect sensors or potentiometers
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.
IP54 enclosure for surface mounting
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.
