Association Reports
The thermostat will report the following on the lifeline association group (Group 1). The
maximum number of devices on the lifeline association group is four (4)
•
Sensor Multilevel Report (temperature) : When temperature changes by at least the
temperature reporting threshold (See Configuration Parameter 0x21)
•
Sensor Multilevel Report (humidity) : When relative humidity changes by at least the
relative humidity reporting threshold (See Configuration Parameter 0x3D)
•
Thermostat Mode Report : When thermostat mode changes locally
•
Thermostat Mode Supported Report : When the thermostat detects a new HVAC
configuration based on automatic wire detection.
•
Thermostat Operating State Report : When thermostat operating state changes
•
Thermostat Setpoint Report : When either the heat or cool target is changed locally
•
Thermostat Fan Mode Report : When fan mode changes
•
Thermostat Fan Mode Supported Report: When the thermostat detects a new HVAC
configuration based on automatic wire detection.
•
Thermostat Fan State Report : When fan state changes
•
Humidity Control Operating State : When humidity control state changes, a humidity
control operating state report is sent.
•
Battery Report : Battery level is reported once per day and when the battery changed by
5% (minimum interval set by configuration parameter 0x3B). If the battery level falls
below the low level (set by configuration parameter 0x1B), the thermostat reports both
the battery level and 0xFF. The thermostat will wait a minimum interval between
battery reports that are based on changes in the detected battery level (set by
configuration parameter 0x3B). The 24 hour battery report is sent regardless of the
setting of parameter 0x3B.
•
Configuration Report (Remote Temperature Status Report): When report temperature
status changes, a configuration report for parameter 0x1E is sent.
•
Humidity Control Mode: When the humidity control mode is changed locally.
•
Humidity Control Setpoint : When the humidity control humidifier setpoint or the
dehumidifier control setpoint is changed.
•
Notification Report : See Notifications section for more information.
•
Device Reset Locally Report : When thermostat is set to default it will notify all nodes on
in the lifeline association group.
