Automatic fan speed controller | Dual motor output 6 A
Product description
The TCMF8-602DM is one of our most recent controllers crafted for precise AC fan speed management in HVAC systems featuring single-phase motors. This robust device showcases a maximum motor current of 6 A per motor output (2 x 6 A), ensuring optimal efficiency for your HVAC configuration. The TCMF8-602DM automatically sets fan speed based on real-time measurements from up to 4 connected HVAC sensors through the RJ45 socket, supporting Power over Modbus. Additional sensors can be incorporated using extra power supplies.
The 2 analogue inputs and 2 analogue outputs provide the tools for customisation tailored to your unique requirements. You can easily download application-specific firmware through SenteraWeb, your dedicated HVAC cloud platform. The TCMF8-602DM seamlessly integrates with an optional Sentera gateway, ensuring a hassle-free connection to SenteraWeb. You can choose between standalone operation or continuous connectivity to the cloud platform after downloading the firmware.
The TCMF8-602DM features a set of diverse functionalities by offering a selection of firmware versions, catering to various HVAC applications such as destratification and demand-based fan speed control. Once you have selected the functionality on our website solution page you can easily download the corresponding firmware from SenteraWeb.
No programming skills are required for this user-friendly controller, but, if necessary, settings can be done via Modbus Holding registers.
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 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.
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 control of AC fans and offers specific solutions depending on the customer’s needs.
Different functionalities
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 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. 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.
Solid enclosure
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.
