DONE M32421 Z-Wave messages Add/ Remove The thermostat can be included or excluded from the Z-Wave network. This action requires the controller set in inclusion mode. The device is included to the Z-Wave network after sending the node information to the controller. The controller is responsible for assigning the home ID and device ID to the included device. The thermostat can also act as a repeater to forward messages to other devices in the Z-Wave network. Repeating messages allows communication of devices that are not in the direct reach of Z-wave protocol.
- Page 13 TH8320ZW Z-Wave messages received, the fan mode is changed to the desired value (if this value is possible). For the thermostat the possible values are On, Auto and Circ. Indoor Temperature The thermostat sends the indoor temperature using the Multilevel Sensor command class.
- Page 14 Installation Guide Special functions Auto Changeover (Setup Function 0300): When set to Auto, the thermostat automatically selects heat- ing or cooling depending on the indoor temperature. Heat and cool settings must be at least 2 degrees apart. Adaptive Intelligent Recovery (Setup Function 0530): Allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the scheduled time.
