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 has an integrated internet gateway that can be connected via Wi-Fi. 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 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?
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 3 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 Do You Connect External Device, 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.
