Irritrol Rain Dial Plus 12 User Manual

The Rain Dial Plus control module is designed to be easily removed for complete
programming in a more convenient setting, or for servicing. The battery keeps the
current time and allows changes to settings until the module is connected to AC power.
To remove the module, pull forward
on the right edge of the module as if
you were going to replace the battery.
Unplug the ribbon cable connector
from the printed circuit board, as
shown in Figure 5, then unsnap the
module from it’s hinges. To reinstall
the module, simply reverse the order
of the removal steps.
Program settings are stored in a unique electronic device called “non-volatile” memory
and retained for up to 10 years even without battery power. The battery maintains the
current date and time.
A two-position sensor switch (as shown in Figure 3 on page 7) is provided to bypass
the (optional) rain sensor function if necessary.
IMPORTANT: If a rain sensor is NOT connected to the controller, the sensor
switch must be in the BYPASS position or the jumper wire attached to
both sensor terminals to enable controller operation.The controller will not
operate automatically if the sensor switch is in the ACTIVE position
without a sensor or jumper wire installed.
