FAQs

What is the primary purpose of the EPH TR1 TR2 Wireless Switch Kit?

The kit establishes a wireless link between two locations to control heating system components like boilers, underfloor manifold valves, and pumps, especially where wired installation is impractical.

What power supply does this kit require?

The EPH TR1 TR2 Wireless Switch Kit requires a standard 230 Vac 50Hz power supply for both the TR1 and TR2 units.

Can I use this kit for smart home integration or app control?

This kit is designed for direct wireless switching of heating system components and does not include smart home integration or app-based control features.

What is the contact rating of the switches?

The contact rating for the switches in the TR1 TR2 kit is 250 Vac 10(3)A.

How far apart can the TR1 and TR2 units be placed?

The effective wireless range depends on the installation environment. Consult the product manual for specific range guidelines and factors that may affect signal strength.

Is this kit suitable for new builds as well as renovations?

Yes, the kit offers installation flexibility and is suitable for both new build projects and retrofit applications where wiring is challenging.

Do I need a professional to install this kit?

Professional installation by a qualified heating engineer or electrician is highly recommended to ensure correct wiring and system integration.

Troubleshooting

TR1 and TR2 units are not communicating wirelessly.

Verify both units are powered on. Check the distance between the units and ensure it is within the recommended wireless range. Re-initiate the pairing procedure as per the installation manual. Ensure there are no significant obstructions or sources of wireless interference between the units.

System is not switching on/off as expected.

Confirm that the TR1 and TR2 units are correctly wired into the heating system components (boiler, manifold, pump). Check the contact rating and ensure it is not being exceeded. Review the system's control logic and ensure the wireless link is active.

Device powers on but shows no signal.

Ensure the power supply to both units is stable and correct (230 Vac 50Hz). Check for any error codes or indicator lights on the units and consult the manual for their meaning.

Inconsistent performance or intermittent connection.

Reduce the distance between TR1 and TR2 if possible. Minimize potential sources of radio frequency interference in the vicinity. Ensure antenna orientation is optimal if applicable.
