STC-3028 Controller.
This controller has two relays, one for temperature control and another for humidity control. This is the 220V version and will work directly from the mains. The relays can handle 220V 10A. The temperature and humidity sensors are packed into one enclosure with a cable to the unit for easy placement away from the controller. This unit is compact and easy to install.
Note:
Although the controller is able to measure and control humidity up to 100%, the sensor can not handle this humidity for long periods of time as per the datasheet of the sensor itself, normal working scope:0 - 80% RH. Sensor reading will deviate if beyond this range, (drift < 3% RH after 200 hours at 90% RH humidity). The working scope is further limited to - 40– 80℃.
