The Rain Dial utilizes a 2.0A Slow-blow fuse to protect the controller on
the 24 VAC input power. If the fuse blows, check for the probable cause
of the condition and take corrective action before replacing the fuse.
WARNING: The 2.0A safety fuse protects the transformer
from damage due to a current overload (short circuit) condition.
For continued protection against risk of fire, replace only with
the same fuse type and rating. Ensure power to the controller
is disconnected prior to removing or installing fuse.
1. Disconnect the main power source to the controller.
2. Open the controller door.
3. Pull the control module open by grasping it from the right edge
(press the module release tab on the outdoor model).
4. Locate the fuse on the PC board (see page 9). Carefully remove
the fuse from the retaining clip.
5. Install a new 2.0A (slow-blow) fuse, ensuring that it is properly
seated in the retaining clip.
6. Reconnect power to the controller.
Note: If the 9V battery did not support the control module power
requirement, current time and day will need to be reset. Refer to
pages 5 and 6 for battery replacement procedure.
