cool setpoint would be set to 72. While the temperature is within this range nothing is done. Once the

temperature falls outside this range the system takes action and switches to the appropriate mode.

5. Humidify/Dehumidify: Some systems can maintain the humidity level within a certain range. These are

similar to temperature setpoints except instead of temperature control equipment the system is controlling

humidify and dehumidify equipment.

Command Interface - SEND_COMMANDs

Various system wide operations may be performed by the NetLinx program via SEND_COMMANDs sent to

the virtual device controlling the thermostats.
