Target/Setpoint temperature

Set Target temperature with resolution 0.1°C

SET

The desired target temperature should be pre-multiplied by 10 to get the value to be send.

Byte index	Hex value - Meaning
0	51 – The command code.
1	XX - Tt [15:8]
2	XX - Tt [7-0]

Target temperature = Tt [15:0] / 10

Example command: 0x510102 => Tt = 0x0102=258

Target temperature = 258 / 10 = 25.8

The desired target temperature should be pre-multiplied by 10 to get the value to be sent. If later the target temperature is adjusted manually by rotating the device outer ring, the new value will be with accuracy 1.0°C
