PROGRAMMING & OPERATING INSTRUCTIONS
CO1903 - RSR Installation Instructions
The CO1903 is designed to accept a “HOLMAN” Rain
Sensor, model CRS1000BC, which has a factory fitted plug.
Install your rain sensor where it can be exposed
to the weather to detect any wet periods. Preferred
mounting locations are rain gutters or attach onto
conduit. Set the “cut off” level on the sensor, and
adjust to suit your particular area.
To install the timer to the rain sensor, simply remove
the rubber plug fitted into the bottom of the tap timer,
and insert the rain sensor plug fitted on the end
of the rain sensor cable.
When the sensor is wet, it will stop the tap timer
from operating any manual or automatic run times.
Once the sensor is dry, the automatic programs will
resume.
To override the sensor,
remove the rain sensor
plug from the tap timer
by simply pulling it out.
This will allow manual
or automatic starts
when the sensor
indicates that it’s WET.
When un-installed, re-fit the rain sensor plug into the
rubber socket that’s provided for added protection.
