CS3000 User’s Guide
Calsense 45
• Maximum rain per hour is used to ensure rain that runs off due to a high rate of rainfall is not
used to offset irrigation. For example, if it rains 2” in an hour, but the site’s soil can only absorb
half an inch of rain before running off, set this to 0.50”.
Maximum rain per 24-hours indicates how much rain is usable within a 24-hour period. This is
generally set two or three times higher than the maximum rain per hour.
Configuring a Wind Gage
If a Wind Gage is physically connected to this controller or another within the FLOWSENSE chain, this
screen provides the ability to specify where the controller is connected. After indicating a Wind Gage is
in use, several settings appear:
• The Pause setting indicates at what speed, in miles per hour (mph), irrigation should be paused.
When the controller detects wind sustained at or above this speed, irrigation pauses minimum
of 10-minutes or until the wind dies down.
• The Resume setting indicates at what speed, in mph, the controller should resume irrigation
after pausing due to wind.
Setting up a Third-Party Rain Switch
The Rain Switch feature allows the controller to respond to a third-party rain switch which will stop
irrigation if rain is detected. For controllers on a FLOWSENSE chain, irrigation is stopped across all
controllers when the rain switch detects rain. A rain switch can be connected to either the Rain Switch
inputs on the Weather Kit (model CS3-W-KIT) or the SW1 input on the POC terminal.
To enable use of a rain switch (Figure 33):
1. From Main Menu, navigate to Weather & Sensors and select Rain Switch. The Rain Switch
screen displays.
2. Specify whether the controller uses a rain switch to prevent irrigation. When set to Yes, a list
displays showing the controller or all the controllers in the chain.
3. Specify which controller(s) have a rain switch attached using +/-.
Caution: Indicating a rain switch is in use when there is not one physically connected will cause irrigation
not to run.
