Commissioning LED indication:
Do not insert the sensor battery until the device is ready for commissioning and the WAC is powered up and available to
pair with the wireless sensors.
When the sensor is initially powered up with the battery inserted it will be un-paired and the LED will flash every second.
This shows that the sensor is searching for an available network.
Once the sensor has joined the network the LED will remain OFF at all times.
LED Indication Sensor Status
LED ashing every 250 milliseconds Sensor identify (see Identify Cluster)
LED ashing every 1 second Sensor is not paired and is searching for a network
LED OFF Device is paired
Factory Reset: (It is possible to restore the device to its factory settings). Also see LED timing below.
To reset an end device; remove the battery, press and hold the PCB push button down while re-inserting the battery. Once
the battery is inserted, release the PCB push button
.
Upon resetting, the device will leave its current network, restore the factory default settings for the minimum, maximum
and delta change reporting along with the polling intervals. Once reset the device will search for strongest HA1.2 and
attempt to join.
Default and Recommended Settings:
Setting Default Range
Minimum Reporting Interval 60 seconds 0-65536 seconds
Maximum Reporting Interval 300 seconds 0-65536 seconds
Delta Change Reporting Threshold 0.5°C 0-32767 (0-327.67°C)
Polling during normal operation 60 seconds 0-65536 seconds (Polling will match the Min Reporting
Value)
Polling (accelerated) upon joining/re-
joining network
Every 2 seconds for 60
seconds
N/A
It is possible to force specic features within the sensor by holding the PCB push button and releasing at certain
points of the LED sequence. To perform one of the below tasks, press and hold the PCB button, the LED will begin
to ash every second, release at the relevant point of the sequence to perform the associated task.
LED Timing Feature
Release after 1st LED ash Sensor reads sensor value and updates clusters
Release after 2nd LED ash No action
Release after 3rd LED ash Initiates the OTA update process
Release after 4th LED ash Factory reset
