Circuit connection: reference circuit diagram to connect the power supply and load, at this time the digital tube (above) display the actual measurement temperature value, digital tube (below) display preset temperature. If the temperature sensor is missing or damaged, the digital tube will display "-". Before use, the buyer must check whether the temperature sensor is installed.

The temperature control output is 10A relay, to meet a variety of high power load, please ensure that the line is correct.

Instruction of indicating lamp and digital tube:

Indicator: put out, indicating that the relay is broken, often bright that the relay closed

Digital tube: display "-", 1, check the temperature sensor missing or damage 2, heating mode, high temperature protection 3, refrigeration mode low temperature protection. In protection mode, the relay is automatically disconnected.

Button use: temperature control panel has three buttons, button + button - set key SET

Key +: realize fast accumulation of values

Keys - to achieve rapid decline in numerical value

Key Restart: Restart button

Set the key SET: to achieve the two layer interface settings, temperature settings, interface parameter settings interface

SETQuick setting of temperature by short press digital tube (down). The preset -20, 0, 20, 40, 60, 100, 80 and other data groups are convenient for users to call quickly. For example: users need to set 68.8 degrees, the first short SET adjusted to 60 degrees, and then by fine-tuning the key to the corresponding temperature can be. Set wait, 5S automatically remember to save data. Compared with the 1 generation thermostat, the 2 generation operation is more convenient and flexible, and the dual LED display the measured temperature and setting temperature more easily.

SETLong press into the parameter setting interface, and P0-P5 is the corresponding parameter setting item. Under the parameter setting menu, the P0-P5 can be switched by short SET. Want to modify a parameter, only need to switch to the corresponding item, through the key add and subtract to set. When the settings are complete, save the data by SET, or wait for 6S to automatically save the data.

 Friendship tips:

P3Setting 1 indicates that the thermostat is running for 1 minutes and stops by pressing SET to trigger again.

P4Setting 1 indicates thermostat and starts work after 1 minutes. After setting, the digital tube will not work until 1 minutes later. Long press SET to trigger again.

P5The default setting is OFFOnce householdsSet the temperature, in order to prevent other people from changing, you can set the P5 option for ON. Once it is set to ON, the data is locked, and the P5 should be set as OFF when it is set again.

Knowledge expansion: the concept of back difference

A simple understanding of return difference is the difference between the back and back. The thermostat can set two modes of heating and cooling, so the backlash has two meanings:

In the refrigeration mode (when P0=C), if the setting temperature is 30 degrees, the return difference is 2, indicating the actual temperature >=32 degrees, the relay is closed, when the actual temperature is <=30 degrees, the relay is disconnected;

In the heating mode (P0=H), if the temperature is set at 30 DEG C and the return error is 2, the actual temperature is >=30 C, the relay is disconnected and closed when the actual temperature is <=28 degrees c..

 

 

 

Application 1: the temperature controller can be widely used in boiler water temperature control, water temperature control of water dispenser and water temperature control of automatic cupboard.

Application 2: the temperature controller can be used for printer equipment, incubation control, and intelligent control of refrigerator and air conditioner.

Using 3:, the temperature can be widely used in the intelligent control of agriculture, temperature control in greenhouse, automatic irrigation and other fields.
