Description
】
The MFT28U stand-alone LCD touch panel is a dedicated field operation
man-machine interface for the DF.. series of networked fan coil controllers. It has a
two-wire RS485 network communication capability and can be connected to a single
fan controller to form a network. Through the MFT28U interface, the user can
individually perform manual start-stop operation, schedule start-stop operation,
temperature adjustment, wind speed switching, and timer shutdown control functions
for the fan controller, as well as real-time monitoring and review of the fan's operating
status. For example, on-site temperature value, system operation mode, wind speed
operation status, fault alarm, etc., touch-sensitive LCD backlit screen, which can be
operated to start, stop, change the temperature and humidity settings, etc.).
With 4 dedicated function keys (

), which can be set quickly, the
transmission distance can reach 1,200 meters; MFT28U-Q is a version that
incorporates air quality sensing functions, and users do not need to install additional
air quality sensors. You can get the air quality value in the environment through
MFT28U-Q. MFT28U can be mounted on the FCnet or SCnet network, allowing users
to check the value or status on the controller at any time, and users can upload media
screens through NFTeditor, and plan various corporate images or energy-saving
promotional screens. Display during operation to enhance the added value of the
product.

With the function of uploading media screens, plan all kinds of corporate images or energy-saving promotion screens, set up to 18 pictures,
displayed when there is no operation, set up to 18 pictures, to enhance the added value of the product. You can choose to play or not to play.
With language, lock, temperature unit, background setting, buzzer, media playback, brightness, clock mode, clock setting adjustment and other
parameter setting functions.
Clock mode setting, when monitoring connection, you can choose to read the clock, with the network time automatic synchronization function,
and accept the network time correction of the central monitoring, so that the controller time in all systems is the same. When there is no
monitoring connection, you can choose the clock to write out, and the panel will display the time, and the connected controller will be
synchronized.
MFT28U-Q contains temperature, humidity, and carbon dioxide sensing functions, which can sense indoor air quality and return its values to the
