NOTES
1. Changing the setpoint will turn Eco Mode off if it is currently on.
2. To leave a parameter unchanged, use “255” as the value for that parameter when sending the command.
3. Schedule Unavailable –> Schedule not programmed or device needs date / time.
Following Schedule –> Running programmed schedule; set points from schedule.
Permanent Hold –> Schedule is not running; set points as adjusted.
Temporary Hold –> Running schedule; set points as adjusted. Returns to following schedule at next schedule event.
4. HQWT-T-HW does not support Eco Mode.
5. For the HQWT-T-HW, this range depends on the programming in the database. The setpoint range is 40-113 °F
(5-45 °C).
6. HQWT-T-HW does not support this integration feature.
7. 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.
8. 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”
– Possible reported values of 21 °C: “021”, “21”, “021.0”, “21.0, “021.00,” “21.00”
– Possible reported values of 21.5 °C: “021.5”, “21.5”, “021.50”, “21.50”
