Servicing Fuse
Two fuses are used for controller circuit protection. Fuse F1 is rated at 3/4
Amp and protects the controller's internal electronics from an excessive
increase in voltage (usually caused by a lightning strike nearby). Fuse F2,
rated at 1-1/2 Amps, protects all 24 VAC output from the terminal strip. A
blown F2 fuse generally indicates that a shorted wiring connection or faulty
control valve solenoid exists. Before replacing fuse, check all wiring
connections at the controller as well as the control valves. If replacing a fuse
does not solve the problem, contact your sprinkler system contractor or local
Toro distributor.
CAUTION
Never install a replacement fuse with a higher amperage rating. Severe
damage to the controller can result.
To Replace Fuse:
1. Disconnect power to controller. See Warning above.
2. Remove lower cabinet cover.
3. Carefully remove fuse from retaining clip and replace with fuse of same
amperage rating.
4. Install lower cover and reinstate power.
5. Reset controller clock to current time. (See page 5.)
WARNING
DISCONNECT 120 VAC POWER TO CONTROLLER AT
SOURCE PRIOR TO SERVICING FUSES. FAILURE TO
COMPLY MAY RESULT IN SERIOUS INJURY AND/OR
EQUIPMENT DAMAGE.
