NOTES
• If the thermostat is setup to use Fahrenheit, it is recommended to use Fahrenheit Integration command set. If it is setup
to use Celsius, it is recommended to use the Celsius Integration command set.
• Allow for reported temperature values to be zero padded, with up to 3 digits before the decimal point, and 2 digits after.
– Possible reported values of 5 °C: “005”, “05”, “5”, “005.”, “005.”, “5.”, “005.0”, “05.0”, “5.0”, “005.00”, “05.00”, “5.00”
– Possible reported values of 5.5 °C: “005.5”, “05.5”, “5.5”, “005.50”, “05.50”, “5.50”
