• Unit is initially
powered up
• Extended power
outage has occurred
and built-in backup
period has expired
• If you are not using a
rain sensor:
The jumper between
the sensor terminal is
missing or loose
• If you are using a rain
sensor:
the sensor has been
activated by moisture
or is stuck "open"
• Jumper between
sensor terminals is
still connected
• Rain sensor is
