Safety Information
- Always disconnect power at the circuit breaker or fuse box before installing, servicing, or removing the timer.
- Installation should be performed by a qualified electrician or a knowledgeable individual familiar with electrical wiring and local codes.
- Ensure the timer's voltage and amperage ratings match the circuit and load requirements. This timer is rated for 120V, 15A.
- Do not exceed the maximum electrical ratings of the timer.
- Protect the timer from moisture and extreme temperatures.
- Verify all connections are secure and properly insulated before restoring power.
Setup and Installation
The Diehl TA4071 is designed for panel mounting. Follow these steps for proper installation:
- Power Disconnection: Before beginning any installation, ensure that the main power supply to the circuit where the timer will be installed is turned off at the circuit breaker or fuse box.
- Mounting: Secure the timer to a suitable panel or enclosure using appropriate fasteners. The timer is designed for panel mount applications.
- Wiring: This timer features four terminal tabs located on the bottom for electrical connections. As an SPST (Single Pole Single Throw) timer, it controls a single circuit. Connect the 120V power supply and the load wires to the designated terminals. Refer to the wiring diagram provided with your specific application or consult a qualified electrician.
- Verification: Double-check all wiring connections for tightness and correctness. Ensure no bare wires are exposed.
- Restore Power: Once installation is complete and verified, restore power to the circuit.

Operating Instructions
The Diehl 24 hr Spa Timer operates on a daily cycle. To set the timer:
- Set Current Time: Rotate the timer dial clockwise until the current time aligns with the fixed pointer or marker on the timer's housing. The dial features a 24-hour scale.
- Set ON/OFF Times: The timer typically uses small, movable pins or segments around the outer edge of the dial to set the ON and OFF times. Push the segments outwards for the periods you want the connected device to be ON, and leave them inwards for the OFF periods. Consult the specific instructions for your timer's pin mechanism if different.
- Observe Operation: The timer will automatically cycle through the set ON/OFF periods every 24 hours. You should hear an audible "click" when the internal switch actuates at the set ON and OFF times.

Maintenance
The Diehl 24 hr Spa Timer is designed for minimal maintenance. However, periodic checks can ensure its longevity and proper function:
- Cleaning: Gently wipe the exterior of the timer with a dry, soft cloth to remove dust and debris. Do not use liquid cleaners or solvents.
- Connection Check: Periodically, with power disconnected, inspect the terminal connections to ensure they remain tight and free from corrosion.
- Environmental Conditions: Ensure the timer is not exposed to excessive moisture, dust, or extreme temperatures, which can affect its performance and lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer not operating (dial not rotating) | No power to the timer; internal motor failure. | Check circuit breaker/fuse. Verify wiring connections. If power is present and dial still doesn't move, the timer may need replacement. |
| Connected device not turning ON/OFF at set times | Incorrect setting of ON/OFF pins/segments; internal switch failure. | Review operating instructions to ensure pins/segments are correctly set. Listen for an audible "click" when the dial passes the set times; if no click, the internal switch may be faulty and require timer replacement. |
| Timer makes unusual noises | Worn internal gears or motor. | While some mechanical timers produce a faint hum, loud or grinding noises indicate wear. Consider replacing the timer if noises are excessive or performance is affected. |
