Uponor Thermal Actuator 230V NC M28 x 1.5 Instruction Manual

1. Produk verbyview

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.

Sleutel kenmerke sluit in:

• Funksie: Normally Closed (NC) - valve closes without current.
• Nominale Voltage: 230V wisselstroom.
• Internal Thread: M28 x 1.5 for secure mounting.
• Aanwyser: Integrated lift indicator for visual status confirmation.
• Verbinding: Equipped with a 0.75 mm² x 1m connection cable.
• Beskerming: Splash-proof design.

2. Veiligheidsinligting

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

• Gekwalifiseerde personeel: Installation and electrical connections must only be performed by qualified and authorized personnel.
• Kragontkoppeling: Always disconnect the main power supply before performing any installation, maintenance, or troubleshooting.
• Voltage: Verseker die toevoer voltage matches the actuator's nominal voltage (230V AC).
• Omgewing: Do not install in environments exceeding the specified operating temperature or humidity ranges.
• Wysigings: Do not modify the actuator or its components. Unauthorized modifications void the warranty and can be hazardous.

3. Installasie en Opstelling

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

1. Skakel af: 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. Mount Actuator: Carefully screw the thermal actuator onto the valve's M28 x 1.5 internal thread. Hand-tighten until secure. Do not overtighten.
4. Elektriese verbinding: 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. Herstel krag: Once all connections are secure and verified, restore power to the heating system.

4. Operasie

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

• Normaalweg Gesluit (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. Onderhoud

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

• Visuele inspeksie: Periodically check the actuator for any signs of physical damage, loose connections, or leaks around the valve.
• Skoonmaak: If necessary, gently wipe the exterior of the actuator with a dry or slightly damp lap. Moenie skuur skoonmaakmiddels of oplosmiddels gebruik nie.
• Funksiekontrole: 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.
