About Automatic Circuit Protection
The TMC-212 features built-in circuit protection to help
prevent damage to the controller caused by excessive
current draw on the station and/or pump start/master
valve circuits. This condition is generally caused by a
shorted valve wire splice, faulty valve solenoid and/or
pump start relay.
If the controller detects an overload
condition on a station, it will bypass
the affected station(s) during an auto-
matic watering cycle. The word
"FUSE" and the defective station number(s) will be
displayed. All remaining stations will continue to operate
as programmed.
If the overload condition occurs on
the pump start/master valve circuit,
the controller will immediately discon-
tinue automatic operation and alter-
nately display: "FUSE - "MV."
To clear the warning display, press the –/
The controller will resume operation as scheduled and
will attempt to run all stations as programmed.
IMPORTANT: Clearing the display does not correct
the cause of the problem. The controller will continue
to bypass the affected station(s) or discontinue
operation until the overload condition is eliminated.
Before continuing to operate the controller, identify
and resolve the cause of the problem. In most cases,
this condition is caused by a faulty valve solenoid,
pump start relay and/or a shorted wire splice.

Adding a 2-station Expansion Module
Note: Expansion modules are available in Standard-
surge (TSM-02) and High-surge (TSM-02-H) versions.
Although the TSM-02-H module can be used in any
TMC-212 controller, it will only provide high (6.0 Kv)
surge protection when installed in Outdoor controller
models TMC-212-ODH and TMC-212-ODH-50H.
