"MAN" - Read Manufacturer data
This command is used to read the Manufacturer ID. The length of DATA is zero bytes. The command always returns
"JHD".
The purpose of defining this command is to be compatible with old SCOM command.
Example:
Read "MAN":
0x07
0xFF
0x4D
0x41
0x4E
0x00
0x1D

0x4E
0x03
0x1B
0x4A
0x48
0x44
0x29
"TMP" - Read Temperature Sensor
The unit features temperature sensor that measures the temperature inside. The TMP command can be used to read
the current sensor temperature. The length of DATA shall be 1 or 2 and contain the following:
Data length is 1, return the value from temperature sensor 0x00

TMP:
A value describing the Read Temperature Type.
Range: Valid levels in table:
0x52 = 'R' Read Current Temperature from on-board Sensor
NUM:
Index of Temperature Sensors
0x00
On-board main sensor
0x01~0x0F Remote sensor
Read Current Temperature:
The unit will reply to this command with an ASCII string indication the temperature in °C, e.g.: "+027.5°C". Read
accuracy is ±0.5°C.
