- 설치: Mount the HTACC-02 relay to the side of the existing junction box using the provided screws. Ensure it is securely fastened.
- 배선: Connect the wires according to the appropriate wiring diagram below for either a 2-wire or 3-wire low-voltag전자 온도 조절기.
- 보안 연결: Use the provided wire nuts to ensure all connections are tight and insulated.
- 전원 복원: 모든 연결이 안전하게 확인되면 회로 차단기에서 전원을 복구하십시오.
5.2 Wiring for a 2-Wire Low-Voltag전자 온도 조절기
This configuration is used when your thermostat only requires R (power) and W (heat call) connections and does not need a common (C) wire.

The thermostat's R and W terminals connect to the relay's R and W wires, respectively. The relay's L1 and L2 terminals connect to the 240V power supply, and the Load terminals connect to the heating element.
5.3 Wiring for a 3-Wire Low-Voltag전자 온도 조절기
This configuration is used when your thermostat requires R (power), W (heat call), and C (common) connections for its operation.

6. 운영
The Briidea HTACC-02 Electric Heating Relay operates automatically in conjunction with your 24V thermostat. When the thermostat calls for heat, it sends a 24V signal to the relay. The relay then closes its internal contacts, allowing 220V-240V power to flow to your heating appliance (e.g., baseboard heater). When the thermostat satisfies the temperature setting, it removes the heat call signal, and the relay opens its contacts, cutting power to the heating appliance.
The relay provides immediate activation, ensuring that your heating system responds promptly to thermostat commands.
7. 유지관리
The Briidea HTACC-02 relay is designed for maintenance-free operation. However, periodic checks are recommended to ensure optimal performance and safety:
- 시각적 검사: Annually inspect the relay and its wiring for any signs of damage, loose connections, or overheating (discoloration).
- 먼지 제거: If installed in a dusty environment, carefully clean any accumulated dust from the relay's exterior to prevent potential overheating. Ensure power is disconnected before cleaning.
- 연결 확인: With power disconnected, gently check that all wire connections remain secure.
Do not attempt to open or repair the relay. Refer all servicing to qualified personnel.
8. 문제 해결
If you experience issues with your heating system after installing the Briidea HTACC-02 relay, consider the following troubleshooting steps:
- 열 없음 :
- 난방 시스템의 회로 차단기가 작동했는지 확인하십시오.
- Ensure the thermostat is set to a temperature above the current room temperature and is calling for heat.
- Verify all wiring connections are secure according to the installation diagrams.
- Check for a green LED light on the relay. If it's not illuminated when the thermostat calls for heat, there might be an issue with the 24V control signal or the relay itself.
- Continuous Heat (Heater won't turn off):
- Ensure the thermostat is set to a temperature below the current room temperature and is not calling for heat.
- If the relay's green LED remains on even when the thermostat is not calling for heat, the relay may be stuck in the closed position and require replacement.
- Verify thermostat wiring for shorts or incorrect connections.
- 온도 조절기가 켜지지 않음:
- Ensure the 24V control wiring (R, W, C) from the relay to the thermostat is correctly connected.
- If using a 3-wire thermostat, ensure the C (common) wire is properly connected.
- Check for power at the relay's input terminals (L1, L2).
If these steps do not resolve the issue, contact a qualified electrician or the manufacturer for assistance.
