Zhejiang temperature and humidity controller manufacturers, wholesale

A temperature and humidity control, product information This product is a significant degree of intelligent temperature and humidity monitoring equipment. With a digital display of temperature and humidity settings and measured values, the work environment can be real-time monitoring of temperature and humidity changes, and according to a preset temperature and humidity control point to initiate the corresponding operation of the circuit, to forcibly change the environment in which the temperature and humidity control in the set within the range of values. With high precision, small size, long life, easy to install, easy to use features. Second, the principle and application of the product through temperature and humidity sensors for temperature and humidity automatic sampling, real-time monitoring, in order to maintain the temperature and humidity of the environment within the required range. 1. Humidity control: when the humidity is higher than the humidity set point, the dehumidification load circuit starts to work to reach dehumidified (or when the humidity is below the humidity set point, start humidification humidification equipment on the environment); 2. Temperature Control: When the ambient temperature is higher than the temperature set point, the cooling load circuit starts to work (or when the ambient temperature is below the temperature set point, start heating load of work); 3. Break alarm: when the load is disconnected or not working properly load damage, the controller issued a disconnection signal and buzzer alarm sounds and control indicator flashes; 4. Over-temperature alarm: When the ambient temperature is greater than the current over-temperature alarm set value, the controller issued a disconnection signal and buzzer alarm sounds, and overtemperature indicator flashes (also can be used to directly control relay trip) ; The products are widely used in the power sector using a variety of low voltage switch cabinets, terminal boxes, box-type substation, isolating switch, circuit breaker mechanism box and other areas related to the need to control temperature and humidity.

Control output: active AC220V / 3A (or passive normally open output according to customer requirements, such as no special instructions for the active output) (1) temperature limit control output: When the ambient temperature> temperature limit, start cooling load; when the ambient temperature <(upper limit - its return difference), the load stop working. (2) The temperature limit control output: When the ambient temperature  (lower limit + its return difference), the load stop working. (3) The upper limit humidity control output: When the ambient humidity> humidity control value, start dehumidifying load; when the ambient humidity <(control value - the difference between its back), the load stop working. (4) Humidity limit control output: When the ambient humidity  (control value + its return difference) load stop working; V. sensor test ⑴, temperature sensor test: can Direct heating or cooling of the sensor, if the display has changed, the sensor's. ⑵, humidity sensor test: Slowly Kazakh gas sensor, humidity display value will increase. After stopping Kazakh gas, humidity will slowly return to ambient humidity. Sixth, Caution (1) Each product includes kit: a master device, temperature and humidity sensors (different models with the corresponding sensor), certificate copy. (2) read the "User's Guide" under the premise wiring according to the instructions, before electricity after confirmation. If You use different from the installation, use of the program of the present specification or to add additional features, please contact us as soon as possible, so that we can provide the relevant documentation, to avoid burning equipment, resulting in a major accident. Note: The sensor leads and connect the power supply can not be bundled or twisted together, do not put the same a metal pipe to prevent electromagnetic interference.
