JS401 is a state-of-the-art multi-functional controller for accurate monitoring of temperature and humidity parameters. It is a perfect choice for climate control systems in residential buildings or commercial facilities. JS401 continuously monitors the relative humidity and precisely measures the air humidity level in a wide range between 20 to 90 %, commanding the climate control equipment to maintain the required user parameters. This humidistat is applied in rooms of various purpose.
The humidistat is designed to control air humidification and dehumidification systems. By increasing or decreasing the air flow rate, it adjusts the air dehumidification capacity and the percentage of moisture in the indoor air. If the air humidity is below the required limit, the air humidifier turns on.
Settings and parameters on the control panel
The display with blue backlighting clearly shows actual values of air temperature and relative humidity in turn. Temperature values are updated every 3 s, while humidity values are updated every 10 s. In addition, there is a real-time clock in the bottom of the display, along with the dehumidifier on/off indication.
There is a number of buttons in the bottom of the panel: ON/OFF, navigation, status selection, and air flow control with low, medium and high speeds to choose from. These buttons allow setting the clock, selecting the required humidity level, selecting the air flow speed, locking the buttons and using other advanced features.
Humidistat or humidity sensor?
JS40 is designed not only for humidity measurement, but also for sending signals to humidification or dehumidification systems. It is a smart controller that both determines moisture content in the air as a humidity sensor, and commands the equipment to adjust the humidity to the required user-defined level of moisture content in the air. JS40 controls the humidity with pin-point accuracy.
JS40 operation modes
With an air dehumidifier connected. If a user-defined humidity level must be maintained, JS40 compares the setpoint and the actual value. When the humidity setpoint is exceeded, the compressor of the dehumidifier starts automatically and runs until the moisture content falls to the required limit. Then the dehumidifier compressor stops. After that, the humidistat monitors the relative humidity at regular intervals.
With an air humidifier connected. If the air is too dry, that is, moisture content in the air is lower than the user-defined value, Mycond JS40 automatically starts the air humidifier. Humidification is performed until the air humidity reached the required optimum moisture content.
These features are very useful for climate control at home, in offices or at commercial facilities with high demands for precise humidity control.
