Pre-Wiring Preparations: Setting Up Your MasterTemp Heater
Before connecting the communication wire, configure your MasterTemp gas heater. Set the heater to "Spa Mode" to maximize the temperature range available to your automation system. This allows the automation system full control over heating, even if you typically use lower temperatures. This simple step ensures your system functions optimally.

Connecting the Low-Voltage Communication Wire
The communication wire connects the EasyTouch system to the MasterTemp heater. It's a simple two-wire connection; color doesn't matter as it only completes a circuit. Locate the appropriate port on your EasyTouch system, often labeled "heater." On the MasterTemp side, find the communication port (check your specific model's manual), often within a small raceway. Connect the wires securely.

For standalone MasterTemp units, a fireman's loop is present. This is bypassed when using communication wiring, replacing the loop with the communication wires for control via the EasyTouch system.

Compatibility and Alternative Systems
This guide focuses on Pentair EasyTouch and MasterTemp systems. However, the principles are applicable to other automation systems like IntelliCenter and Jandy, though port locations vary. Even heat pumps can be integrated using this two-wire method, connecting to the appropriate port on your EasyTouch system. Adapting this method requires consultation with your system's specific manual.


Troubleshooting and Final Steps
After wiring, reassemble the heater panel. Verify your connections. If you encounter issues, double-check the wiring and ensure the communication ports are correctly identified on both units. Consult your specific equipment manuals if problems persist. Once everything is connected, test the system to ensure the EasyTouch correctly controls the heater's operation.

Conclusion
Integrating your Pentair EasyTouch automation system with a Pentair MasterTemp gas heater enhances your pool's control and convenience. While initially requiring some technical knowledge, the steps outlined in this guide provide a clear pathway. Remember to always prioritize safety and consult your manuals for detailed instructions specific to your models. The benefits of automated pool temperature control outweigh the initial effort.
