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 –/OFFbutton. 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.

1.Turn the control dial to the OFF position.

2.Remove the access cover.

3.Place the back of the station module squarely between the guides of the first open expansion slot (from left to right). Pushing lightly on the bottom of the module, slide it upward until it locks into position.

4.To connect the valve wires, refer to “Connecting The Valves” on page 7.

5.Reinstall the access cover.

6.To set the station time, refer to “Setting Station Times” on page 28.

7.To test the operation of the added station(s), refer to

“Manual Mode” on page 31.
