HVAC: Command Summary
HVAC Integration commands allow the user to access the HVAC components and features of the
system. The user can modify HVAC parameters like the operating mode, fan mode etc., as well as
monitor the changes to these parameters as they occur in the system.
HVAC Command Format
Use “HVAC Command-specific fields” tables
to complete these command fields.

NOTES
1. These commands are supported only for HomeWorks QS, RadioRA 2, myRoom Plus.
2. Changing the setpoint will turn Eco Mode off if it is currently on.
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. To leave a parameter unchanged, use “255” as the value for that parameter when ending the command.
5. Allow for reported temperature values to be zero padded, with up to 3 digits before the decimal point, and 2 digits after.
