1. Introduction
This manual provides essential information for the safe and efficient use of your Weathermatic PL1600-SL1600 Series 120V Transformer. This transformer is designed for compatibility with Weathermatic PL1600 and SL1600 controllers, providing the necessary power for their operation. Please read this manual thoroughly before installation and operation.
2. Important Safety Information
WARNING: Risk of Electric Shock. Installation should only be performed by qualified personnel.
- Always disconnect power to the controller before installing or servicing the transformer.
- Ensure all wiring connections are secure and comply with local electrical codes.
- Do not expose the transformer to excessive moisture or extreme temperatures.
- Verify the input voltage matches the transformer's rating (120V).
- Keep children and unauthorized persons away from the installation area.
3. Installation Instructions
The Weathermatic 170-085SA transformer is designed for straightforward replacement or new installation within compatible Weathermatic controllers. Follow these steps carefully:
- Power Disconnection: Before beginning any work, ensure the main power supply to your Weathermatic controller is completely disconnected at the circuit breaker. Verify with a voltage tester.
- Access Controller: Open the controller housing to access the existing transformer or the designated transformer mounting area.
- Remove Old Transformer (if applicable): Carefully disconnect the wiring from the old transformer, noting the connections (input and output). Remove any mounting hardware.
- Mount New Transformer: Position the new Weathermatic 170-085SA transformer in the designated location. Secure it using appropriate mounting hardware. The transformer features a stainless steel housing for durability.
- Wiring Connections:
- Connect the 120V AC input wires from the controller's power supply to the primary side of the transformer. Refer to your controller's specific wiring diagram for correct terminal connections.
- Connect the low-voltage output wires from the secondary side of the transformer to the controller's low-voltage input terminals. The transformer features high-quality copper wire for reliable conductivity.
- Ensure all connections are tight and insulated to prevent short circuits.
- Secure Housing: Close and secure the controller housing.
- Restore Power: Carefully restore power to the controller at the circuit breaker. Observe the controller for proper operation.

4. Operation
Once properly installed, the Weathermatic 120V Transformer operates automatically to convert the incoming 120V AC power to the lower voltage required by your Weathermatic PL1600 or SL1600 controller. The transformer is a passive component and does not require user interaction for its function.
The controller will power on and function as designed, provided the transformer is supplying the correct voltage and current. The transformer is designed for continuous operation within its specified limits.
5. Maintenance
The Weathermatic 120V Transformer is designed for minimal maintenance. However, periodic checks can help ensure its longevity and reliable performance:
- Visual Inspection: Annually inspect the transformer and its wiring for any signs of physical damage, corrosion, or loose connections. The unit features corrosion-resistant components.
- Cleanliness: Ensure the area around the transformer within the controller is free from dust, debris, and moisture buildup.
- Ventilation: Confirm that the controller housing allows for adequate ventilation to prevent overheating, although the transformer itself is designed to operate efficiently.
- Fuse Check: If the controller loses power, and other power sources are confirmed, check the fuse integrated into the transformer's input wiring. Replace with a fuse of the exact same rating if necessary.
6. Troubleshooting
If your Weathermatic controller is not receiving power after transformer installation, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller has no power. | No input power to transformer. | Check circuit breaker and wall outlet. Ensure power is restored to the controller's supply line. |
| Controller has no power. | Blown fuse on transformer input. | Inspect the fuse on the red input wire. Replace with a 1A, 250V fuse if blown. Ensure the cause of the fuse blowing (e.g., short circuit) is resolved. |
| Controller has no power. | Loose or incorrect wiring connections. | WARNING: Disconnect power first. Recheck all wiring connections for tightness and correct polarity according to the controller's diagram. |
| Transformer humming loudly or emitting smoke. | Internal fault or overload. | WARNING: Immediately disconnect power. Do not attempt to repair. Replace the transformer. This indicates a serious issue. |
If troubleshooting steps do not resolve the issue, contact Weathermatic customer support or a qualified electrician.
