Product update: Product updated to TH330B. 

This plug-n-play temperature and humidity controller TH330B can be used for sausage curing, green houses, incubator and other similar applications. This controller (TH330B) doesn't have WIFI function. If you need WIFI humidity controller, please check AW-TH330A instead (ebay item 112330601563). 

This controller can control both temperature (heating or cooling) and humidity (humidifying or dehumidifying) at the same time. You only need to plug in the power cord plugs from your heater/cooler and/or humidifier/dehumidifier directly to the outlets on the controller. The controller has a two-line LED display, two output sockets, one sensor module and one input power cord. The top displays the measured temperature value (either in Celsius or Fahrenheit), and the bottom shows the measured humidity value (RH%). The left output socket connects to the heating/cooling devices while the right output socket is for a humidifier/dehumidifier. The sensor module contains both temperature and humidity sensors (2-in-1 sensor).

This controller can be used in high relative humidity (>85%) and condensing environments, which are among the most challenging conditions for humidity controllers. For example, when controlling the humidity of a curing fridge at temperatures below the dew point of the ambient environment, opening the fridge door will cause water to condense onto the sensor. Also, when controlling the humidity at a humidity level that is close to 100%, slight temperature drop may cause condensation on the sensor.  As a result, this will usually lead to unstable readings on humidity sensors while also potentially damaging the sensor. This controller, however, is equipped with the utmost robust sensor available on the market that is able to withstand such situations.

Note: If you need to control both humidifier and dehumidifier at same time, you can either use HD330 dual-channel humidity controller, or use two sets of TH330B. If you need to control both heater and cooler at same time, you can either use TD130 dual-channel temperature controller, or use two sets of TH330B. 

Exclusive features: New humidity control parameters are introduced to limit the humidity output. In controlling curing chambers, there typically is a significant decrease in relative humidity whenever the compressor is running, or a large increase when the chamber door is opened. Humidity controllers on the market typically enable the humidity output immediately, which will create a big reading swing. However, with new humidity controller parameters in this controller, users are able to limit the humidity output to reduce reading swings. These parameters can be accessed directly through the controller’s keypad.

Note for TH330B: It has a new function that allows the same device (for example, a ventilation fan) to be activated by both temperature and humidity conditions. Please see the manual of TH330B for details about the new parameter 'RLY' in the System menu.  

Specifications

Warranty: 1 year for controller. 90 days for sensor

Note:

• The controller can display the temperature unit in Celsius or Fahrenheit.
• Unlike the PID controllers we sell, this on/off controller will not hold the temperature as tight if the system has very slow and delayed response. Some temperature overshot is normal.
• Although both temperature and humidity output can handle up to 15Amp of power,  the combined total power of the two channels are limited to 15A due to the limitation of input power cord.
• For TH330B, the input power plug is a US NEMA 5-15P plug. The output power plug is US NEMA 5-15R socket.
