RFM-LR1
There are at least five startup transmissions. The Status command (index 0x20) is sent unless a reply to a
downlink is sent. If no replies are sent the Status commands are sent with increasing intervals starting with
15 seconds and ending with two minutes. This startup sequence should be utilized to set the starting value of
the water meter (if not equal to 0 m
3
). For accurate calibration, the water meter should not be used during the
calibration.
Physical installation

it. The installer mounts the RFM-LR1 unit on the GSD8-RFM and mount the locking pin and seal.
