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.
