HVAC controller for EC fans
Product description
The ECMF8-DM is a fan speed controller for destratification, air curtains, heat recovery units, and EC fans. It operates on 85-264 VAC/50-60 Hz power with an Imax of 750 mA.
It features Modbus RTU communication, two analog/modulating/digital inputs, two tacho inputs, and two analog/modulating outputs (0-10 VDC / 0-20 mA / 0-100% PWM / digital ON/OFF). The tacho inputs provide feedback from EC fans, and an onboard 24 VDC power supply can power external sensors. An RGB LED indicates its status.
Application-specific software can be downloaded via SenteraWeb, but an external SIG-M-2 or SIG-WM internet gateway is required for connectivity.
Designed for indoor wall mounting, it has an IP54 protection rating and a 2-year warranty.
Additional specifications and description
How Do You Download and Connect ECMF8 Controller Software?
ECMF8 controllers require application specific firmware. This firmware can be downloaded via SenteraWeb - your personal HVAC cloud platform. This is the basic version of the controller series, so a separate internet gateway is required to connect to SenteraWeb for the firmware download. Once the firmware is downloaded, it is possible to use this controller standalone or to keep it connected to SenteraWeb.
Why Use EC Motors in HVAC Systems, and How Does the ECMF8 Help?
The importance of HVAC systems has increased when it comes to heating or cooling large office, public, industrial or residential buildings. Rapid air movement from one place to another is highly needed to maintain a cooling and heating system simultaneously within an HVAC system. Good old AC motors were widely used to maintain air driving force, but due to their disadvantage of running only on full power, they are not the better choice nowadays. Replacing AC motors with advanced EC motors makes sense due to their numerous advantages, namely no buzzing and humming, precise environmental control, cheaper to run and, last but not least, better yield.
The ECMF8 has been developed with this idea in mind – to control EC fans in a variety of applications.
How Do You Easily Upload Application-Specific Software to the ECMF8?
We offer a limited number of specific firmware versions for typical HVAC applications (e.g. destratification control with EC fans). The ECMF8 can be used for ventilation control according to sensor measurements and to run according to defined downloadable functionalities (solutions) and run times (schedules), to be able to switch, stage or combine outputs or to be used as a simple air handling or air curtain controller.
First, select the required functionality via our website solution tab, then download the application specific firmware. If necessary, it is possible to adjust some settings via the Modbus Holding registers. No programming is required!
How Does the Controller Control EC Fans, and What Are the External Device Connection Options?
This controller has two analogue outputs to control EC fans. All product version can control more than one EC fan and/or variable frequency drive via the two analogue outputs, which is why we call them “dual”.
They also feature tacho inputs for better motor control. The tacho signal of the EC fans (if available) can be read out to check the status of the fans and to monitor fan speed.
External HVAC sensors or potentiometers can be connected via Modbus RTU communication or via the analogue inputs. The integrated 24 VDC power supply (Power over Modbus) to connect external sensors or potentiometers without the need of a special supply module. The 24 Volt supply and Modbus communication can be combined via one cable - we call it Power over Modbus or PoM. The analogue input or output type and all other settings can be adjusted via the Modbus Holding registers.
Where and How Should the Controller Be Mounted?
The enclosure of the ECMF8 is designed for indoor use and can be installed on a flat surface. 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 is manufactured in house and is constructed from high-quality r-ABS VO (UL94) plastic. This type of plastic possesses flame-extinguishing properties, toughness, and resistance to impacts. The enclosure offers an IP54 protection rating.
