5.1 Pre-Installation Checklist:

Ensure power is OFF at the main circuit breaker.
Verify the voltage and amperage of your load are within the timer's specifications (240VAC, 40A, 3HP max).
Gather necessary tools: screwdriver, wire strippers, voltage tester, conduit fittings (if applicable).
Confirm you have appropriate copper wiring (AWG 8-14, 90°C/194°F rated).
A Z-Wave hub is required for smart control features.

5.2 Mounting the Timer:

Choose a suitable outdoor location, away from direct water spray, but accessible for maintenance.
Mount the timer securely to a flat, vertical surface using appropriate screws and anchors.

5.3 Wiring Instructions:

The DEWENWILS PTZA02 is designed to control a single 240VAC load. Refer to the internal wiring diagram and the images below for guidance.

A simplified diagram illustrates how to connect a single 240VAC load, with Power L1 connecting to Line 1, Power L2 connecting to Line 2, and the load connected between Load L1 and Load L2.

Ensure power is OFF. Double-check with a voltage tester.
Open the timer's enclosure.
Remove the appropriate knockouts for your conduit or cable entry.
Connect the incoming 240VAC power lines:
- Connect Power Line 1 (L1) from your circuit breaker to the terminal labeled Line 1.
- Connect Power Line 2 (L2) from your circuit breaker to the terminal labeled Line 2.
Connect your 240VAC load (e.g., pool pump, water heater):
- Connect one wire from your load to the terminal labeled Load L1.
- Connect the other wire from your load to the terminal labeled Load L2.
Ensure all connections are tight and secure. Replace the clear protective cover over the terminals.
Close and latch the enclosure door securely to maintain its weatherproof rating.

Note: The innovative wiring design aims to simplify installation. Always follow the specific diagram provided inside the unit and consult a professional if unsure.

Seal Integrity: Ensure the enclosure door gasket is intact and the door latches securely to maintain its IP44 weatherproof rating.

8. Troubleshooting

If you encounter issues with your DEWENWILS Z-Wave Timer, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Device does not power on.	No power from circuit breaker; loose wiring connection.	Check circuit breaker. Ensure power is OFF, then check all wiring connections for tightness.
Load does not turn ON/OFF.	Incorrect wiring; overloaded circuit; device malfunction.	Verify wiring against the diagram. Ensure load does not exceed 40A/3HP. If issues persist, contact support.
Cannot pair with Z-Wave hub.	Hub not in inclusion mode; device too far from hub; interference.	Ensure hub is in inclusion mode. Try pairing closer to the hub. Check for other wireless devices causing interference.
Z-Wave control is intermittent.	Weak Z-Wave signal; interference.	Ensure the Z-Wave network has enough repeaters. Relocate the hub or timer if possible.

If the problem persists after attempting these solutions, please contact DEWENWILS customer support.
