Irritrol MC-E - Manual (Page 32)


Rain Off
The MC-E provides Rain Off to temporarily suspend the controller’s automatic watering. When Rain Off is activated,
automatic watering cycles are halted until the Rain Off duration has elapsed. Rain Off can be programmed from 0 (Rain
Off deactivated) to 14 days.
Activate Rain Off
Step 1 – Place the Function Dial to the Rain Off position.
Step 2 – The MC-E will execute a 3-second countdown to cancel any active watering. In this function dial position, all
automatic watering will halt until it is returned to Auto Run position.
Step 3 – You can also set a specific rain delay duration in days.
Example: Place the controller in Rain Off for three days. Enter the desired
days off, in this case
, and press the button to accept.
3 Days indicate that the current day is day number 3. The controller will countdown at day change
until day 0 is met. At day 0, all automatic watering is restored. Disable the Rain Off feature by entering a Rain
Off value of 0 day. Press the button to clear any “Key Entry Error”.
Step 3 – Return the Function dial to the AUTO/RUN position to exit Rain Off.
If station #2 is set as the normally-open master and activated (for flow sensing feature) RAIN OFF
will not shut it off.
Semi-Auto Operation

Step 2- Enter the program number you want to activate. Press to accept. Press either the button for the number
of the first station in the program or the number of the station within the program where you wish to start the
semi-automatic run. Then press
. (If you do not remember the first station in the program, pressing “1” will
automatically select the program’s first station for the semi-auto start.)
Example: With the Function Dial at SET PROGRAM , press and . If station 8 is where you want
Program 2’s semiautomatic run to start, press and to start the operation. If you do not know which
stations are in Program 2, just press and . Program 2’s first station will start.
Step 3 – Return the Function Dial to AUTO/RUN position. The controller will finish the semi-auto run of the
remaining stations for the selected program and then await its next automatic start time.
