Uponor Thermal Actuator 230V NC M28 x 1.5 Instruction Manual

1. انتهى المنتجview

The Uponor Thermal Actuator (Model 1022244) is designed for precise control of valves in Uponor, Polytherm, and Wirsbo Vario B underfloor heating distributors. This actuator operates on 230V AC and features a Normally Closed (NC) function, meaning the valve is closed when no power is supplied and opens when power is applied.

تتضمن الميزات الرئيسية ما يلي:

• وظيفة: Normally Closed (NC) - valve closes without current.
• المجلد الاسميtage: 230 فولت تيار متردد.
• Internal Thread: M28 x 1.5 for secure mounting.
• مؤشر: Integrated lift indicator for visual status confirmation.
• اتصال: Equipped with a 0.75 mm² x 1m connection cable.
• حماية: تصميم مقاوم للرذاذ.

2. معلومات السلامة

Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or property damage.

• شخص مؤهل: Installation and electrical connections must only be performed by qualified and authorized personnel.
• انقطاع التيار الكهربائي: Always disconnect the main power supply before performing any installation, maintenance, or troubleshooting.
• المجلدtage: ضمان حجم العرضtage matches the actuator's nominal voltagه (230 فولت تيار متردد).
• بيئة: Do not install in environments exceeding the specified operating temperature or humidity ranges.
• التعديلات: Do not modify the actuator or its components. Unauthorized modifications void the warranty and can be hazardous.

3. التثبيت والإعداد

This section provides instructions for the correct installation of the thermal actuator onto your underfloor heating manifold.

1. إيقاف التشغيل: Ensure the main power supply to the underfloor heating system is completely disconnected at the circuit breaker.
2. Identify Valve: Locate the specific valve on the Uponor, Polytherm, or Wirsbo Vario B underfloor heating distributor where the actuator is to be installed.
3. مشغل التثبيت: Carefully screw the thermal actuator onto the valve's M28 x 1.5 internal thread. Hand-tighten until secure. Do not overtighten.
4. التوصيل الكهربائي: Connect the 230V AC electrical cable from the actuator to the appropriate control terminal on your heating system's wiring center. Ensure connections are secure and comply with local electrical codes. The actuator functions as Normally Closed (NC), meaning it will open the valve when power is supplied.
5. Verify Indicator: After connection, the lift indicator on the actuator should be visible. Its position will change once power is applied and the actuator begins to operate.
6. اعادة الطاقة: Once all connections are secure and verified, restore power to the heating system.

4. التشغيل

The Uponor Thermal Actuator operates based on the electrical signal it receives from the heating control system.

• Normally Closed (NC): When no electrical current is supplied to the actuator, the valve remains closed, preventing water flow.
• Valve Opening: When the heating control system sends a 230V AC signal to the actuator, it begins to heat up internally. This causes a wax element to expand, slowly pushing the valve stem open. This process typically takes a few minutes.
• Valve Closing: When the electrical signal is removed, the actuator cools down, and the wax element contracts, allowing the valve to close.
• Lift Indicator: The transparent lift indicator on the side of the actuator provides a visual confirmation of the valve's status. When the valve is open, the indicator will be in a different position compared to when it is closed.

5. الصيانة

The Uponor Thermal Actuator is designed for long-term, maintenance-free operation. However, periodic visual inspections are recommended.

• التفتيش البصري: Periodically check the actuator for any signs of physical damage, loose connections, or leaks around the valve.
• تنظيف: If necessary, gently wipe the exterior of the actuator with a dry or slightly damp القماش. لا تستخدم المنظفات أو المذيبات الكاشطة.
• الاختيار وظيفة: Observe the lift indicator during heating cycles to ensure the actuator is opening and closing the valve as expected.

No internal maintenance or lubrication is required for this device.
