A qualifier byte of 0x12 indicated that the value contains one decimal point and the units
are °F , e.g., 98.6°F.
Example to set setpoint to 25°C:
If the temperature units are unknown, before changing the setpoint send a command to request
setpoint. The response will include both the precision and units. Precision is fixed at 0.1 and units can
be either °C or °F. If the units are already known skip to step 3.
1. Master sends: CA 00 01 70 00 8E (REQ SETPOINT1)
2. Slave responds: CA 00 01 70 03 11 00 C8 B2 Precision =0.1, units =°C, value=200
(200 x 0.1°C=20.0°C)
Response indicates:
uses a 2 byte integer (nn=03)
precision and units are 0.1°C (d1=11)
3. Master sends: CA 00 01 F0 02 00 FA 12 (Set Setpoint 1 to 25.0°C)
4. Slave responds: CA 00 01 F0 03 11 00 FA 00 Precision =0.1, units =°C, value=250
(250 x 0.1°=25.0.0°C)
