Wiring Diagram
The Wattive BHT-006GCLW (GC model) is designed for boiler/wall-mounted boiler heating systems. It uses potential-free contacts to control the boiler.

The wiring diagram illustrates connections for live wire, neutral wire, and dry contacts to the boiler. Terminals 1 and 2 are for dry contacts, 3 and 4 for 95-240V AC power. Ensure proper electrical safety during installation.
Wiring Instructions:
- Terminals 1 & 2: Used for connecting the dry contacts of the boiler. These contacts are potential-free and provide an ON/OFF signal to the boiler.
- Terminals 3 & 4: For 95-240V AC power supply. Connect the live wire to one and the neutral wire to the other.
- Terminals 5 & 6: For connecting external sensors (if applicable). If no external sensor is used, no connections are required for these terminals.
Warning: Electrical Shock or Equipment Damage Hazard. Disconnect power supply before installation. Improper wiring can cause damage to the thermostat or boiler.
