Remark:

1. When thermostat sends collected temperature data to upper computer, the value of collected temperature should be multiplied by 2 and sent completely by the format of HEX because the accuracy is 0.5℃.

For example: When the collected temperature is 25.5℃, the value sent by thermostat to the upper computer will be 33H (the demical is 51 );

Similarly, When upper computer sends set temperature data to thermostat, the value of set temperature should be multiplied by 2 and sent completely by the format of HEX because the accuracy is 0.5℃.

For example: When the set temperature is 25.5℃, the value sent by upper computer to the thermostat should be 33H (the demical is 51).

E.G.: Read Temper= 25.5°C

The send(or receive) value is 25.5*2=51

The data in HEX =33H

2. How to change thermostat IP address?

During power off, press button M and button Clock for 5 seconds at the same time into high senior options.

Press M to item 2.

Then press up and down to change the relative value. The default is 0x01.

All data will be saved only after a restart.
