NOTES
1. HomeWorks QS software version 4.1 and higher.
2. Changing the setpoint will turn Eco Mode off if it is currently on.
3. To leave a parameter unchanged, use “255” as the value for that parameter when ending the command.
4. Allow for reported temperature values to be zero padded, with up to 3 digits before the decimal point, and 2 digits after.
