    The WH135 dehumidifier for the basement and crawl space is powerful and efficient. Through tightly designed, the WH series dehumidifier has various control methods and good dehumidification performance.

    Various control methods

    First, on-board control. Connected through four conductors, terminal type XH-4Y, using UART serial communication mode. The controller is equipped with an LED screen, which displays the ambient temperature, humidity, wind speed gear, clock, equipment running time, system running state (dehumidification, defrosting, drainage), fault code, etc.

    Second, external control. Connect through 6P6C telephone line, terminal model RJ12, Mod-bus serial communication mode. The controller is equipped with an LED screen, which displays the relevant information.

By issuing the control/query command from the upper computer, you can switch on and off the machine, set the humidity value and wind speed gear, enable/disable the continuous dehumidification mode, query the current temperature and humidity, and display the fault code.

    Fourth, compatible with the third-party control. Connect a third-party controller through a six-bit wiring block (FLOAT--FLOAT--DHUM--R--FAN--C) for dehumidification, ventilation, and full water protection. (Note: the output voltage between R-C and R-C is 12VDC, compatible with Honeywell controllers)

    Save space

    The WH series dehumidifier is relatively small in size and suitable for concealed installation, which is easy to connect to an air duct and a drainage pipe. Installing the dehumidifier on the ceiling or wall can reduce the sense of the existence of the dehumidifier and save indoor space.

    Dry wet clothes

    When you hang wet clothes indoors to dry, the moisture from the clothes evaporates into the air, increasing the humidity levels in the room. The WH135 dehumidifier can help remove this excess moisture from the air, which can speed up the drying process.

    Protect floors, walls, and other belongs

    Mold and mildew can grow on walls, floors, and other surfaces in a damp environment. By removing excess moisture with a WH135 home dehumidifier, you can help prevent mold and mildew growth and protect your home from damage.

    Reduce musty odors

    Musty odors can be a sign of excess moisture in your home, and can be difficult to eliminate. By using a WH135 dehumidifier for home to remove excess moisture, you can help reduce musty odors and create a more pleasant living environment.
