Automatic AC fan speed controller | dual motor output 3 A
Product description
Upgrade your HVAC system with the TCMF8-302DM, an advanced controller for precise AC fan speed control in single-phase motor systems.
This device offers a maximum motor current of 3 A per output (2 x 3 A), ensuring optimal efficiency. It automatically adjusts fan speed based on real-time data from up to four connected sensors via a Power over Modbus (PoM) RJ45 jack.
The TCMF8-302DM provides unmatched flexibility with two analog inputs, two analog outputs, and two tacho inputs, allowing for tailored customization. Firmware can be easily downloaded via your personal SenteraWeb cloud platform.
While it lacks an integrated internet gateway, it is compatible with an optional Sentera gateway for seamless connection to SenteraWeb. After downloading the firmware, you can choose between standalone operation or a permanent cloud connection.
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 is an AC Fan and How is it Controlled with the TCMF8?
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.

What Types of Fans Does the Controller Manage, 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. Thanks to the accurate motor control, humming motor noise at low speed remains limited.
How Does the Sensor Prevent Overheating, and What is the TK Connection?
How are External Devices Connected to the Sensor, 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.
