Refer to the information below for detailed sensor operating instructions.
Push button
The push button can be pressed through a hole from the bottom side of the sensor, with a slim tool (Figure 4). Each recorded button press is
signaled by 2 yellow LED flashes.
• Short push
One short push starts the commissioning procedure if the sensor is in the decommissioned (energy saving / hibernation) mode. If the sensor
is already commissioned, it will enter “demo mode” for a 5min timeout interval.
• Long push
One long push puts the sensor into decommissioned / hibernate mode. The long push is confirmed by one red LED flash roughly 1 second
after 2 yellow LED push signaling flashes. After a red LED signal, the button should be released in order to prevent another unintended short
push detection.
Multi-colour LED
The multicolor LED is hidden under the top plastic cover, positioned on left (Figure 4). In normal state the LED is off in order to conserve battery
life. It is only used to signal the following special events:
• 2 YELLOW flashes confirm each button push taken into account by the sensor.
• 1 RED flash acknowledges a long push. The decommissioning procedure and a sensor reset will be executed, then the sensor will
enter hibernation mode.
• 3 RED flashes signal a commissioning procedure failure. The sensor stays in decommissioned / hibernation mode.
• 3 GREEN flashes signal a commissioning procedure success. The sensor will enter demo mode for 5 min. This demo mode will
automatically timeout after 5 minutes. The sensor then stays in commissioned mode, periodically transmitting the measured values to
the receiver.
• 1 GREEN flash acknowledges a valid GP command received by the sensor in demo mode. This feature can be used as a feedback to
an installer to confirm that the sensor is still in range during the commissioning (it works only in demo mode). In this case the receiver
has to be programmed to send an acknowledgement command to the sensor after the sensor data report frames.
The multiple LED ashes are executed only in 1/2 second intervals.
Factory Mode
The wireless CO
2
+ TRH sensor is in a deep sleep mode waiting for a button push. No measurements, no radio communications are preformed.
Operating Modes
Commissioning
During commissioning the wireless CO
2
+ TRH sensor will automatically find and pair with the nearest compatible ZigBee Green Power receiver.
ZigBee parameters (e.g. operational channel, Src-ID, PAN-ID, security level and key) are exchanged between the sensor and receiver in order to
establish a reliable and secure link.
During commissioning the sensor is presented as an UNSPECIFIED DEVICE (GP ModelID = 0xFE) with the GP Product ID = 17305 (0x4399) and
its unique source ID (SrcID). The SrcID of each sensor is marked on its backside (Figure 5). The receiver should be ZigBee 3.0 compliant.
The commissioning procedure can be triggered only from the Decommissioned / Hibernation Mode by a long push of the button. The
commissioning procedure can be resumed through the following steps:
1. Set a ZigBee operational channel (11 - 26) and the PAN-ID of your network (0xFFFF by default) on your ZigBee 3.0 compliant receiver.
2. Put the receiver into the automatic commissioning mode (opened for the commissioning and accepting the commissioning with GP ModelID
= 0xFE and GP Product ID = 17305 devices).
3. On the wireless CO
2
+ TRH sensor press the push button once to start the bidirectional ZGP commissioning. The button actuating is
immediately confirmed by two yellow LED pulses. The sensor then automatically scans all ZigBee channels (channel 11-26) in order to find
the nearest ZGP Proxy device (receiver in commissioning mode) and initiates the pairing.
4. Wait approximately 10s – during this time the sensor automatically performs the commissioning. The LED will not flash during this period
(even if you push the button again).
5. Commissioning success is indicated by 3 green LED pulses. You can check measured data reported from the sensor to the receiver. If the
commissioning fails (indicated by 3 red LED pulses) please ensure the sensor is in Factory Mode and in proximity of the receiver, then repeat
the procedure.
