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/master valve cir-
cuits.
If the controller detects an over-
load condition on a station, it will
bypass the affected station(s) and
display the word FUSE with the
affected station number(s). All remaining stations will
operate as programmed for automatic operation.
If the condition occurs on the
pump/master valve circuit, the
controller will alternately display
MV and FUSE and discontinue
the program operation.
To clear the warning display,
press the –/ button . The controller will continue to
OFF
operate as scheduled and will attempt to run all stations
as programmed.
IMPORTANT: Clearing the display does not correct
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
remove the source of the problem. In most cases, this
condition is caused by a faulty valve solenoid, pump start
relay and/or shorted wire splice.

Adding a 2-Station Expansion Module

Note: Expansion modules are available in two versions:
TSM-02 Standard-surge module and TSM-02-H High-
surge module. Either module type can be used in any
TMC-212 controller model, however, the TSM-02-H
module will only provide additional surge protection
when installed in outdoor high-surge controller models
