Uponor Thermal Actuator 230V NC M28 x 1.5 Instruction Manual

1. ഉൽപ്പന്നം കഴിഞ്ഞുview

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.

പ്രധാന സവിശേഷതകളിൽ ഇവ ഉൾപ്പെടുന്നു:

• പ്രവർത്തനം: Normally Closed (NC) - valve closes without current.
• നാമമാത്ര വോളിയംtage: 230V എസി.
• Internal Thread: M28 x 1.5 for secure mounting.
• സൂചകം: Integrated lift indicator for visual status confirmation.
• കണക്ഷൻ: Equipped with a 0.75 mm² x 1m connection cable.
• സംരക്ഷണം: Splash-proof design.

2 സുരക്ഷാ വിവരങ്ങൾ

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

• യോഗ്യതയുള്ള ഉദ്യോഗസ്ഥർ: Installation and electrical connections must only be performed by qualified and authorized personnel.
• വൈദ്യുതി വിച്ഛേദിക്കൽ: Always disconnect the main power supply before performing any installation, maintenance, or troubleshooting.
• വാല്യംtage: വിതരണം വോളിയം ഉറപ്പാക്കുകtage matches the actuator's nominal voltagഇ (230V എസി).
• പരിസ്ഥിതി: Do not install in environments exceeding the specified operating temperature or humidity ranges.
• പരിഷ്കാരങ്ങൾ: Do not modify the actuator or its components. Unauthorized modifications void the warranty and can be hazardous.

3. ഇൻസ്റ്റലേഷനും സജ്ജീകരണവും

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

1. പവർ ഓഫ്: 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. ഇലക്ട്രിക്കൽ കണക്ഷൻ: 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. പവർ പുന ore സ്ഥാപിക്കുക: Once all connections are secure and verified, restore power to the heating system.

4. ഓപ്പറേഷൻ

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

• സാധാരണയായി അടച്ചിരിക്കുന്നു (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. പരിപാലനം

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

• വിഷ്വൽ പരിശോധന: Periodically check the actuator for any signs of physical damage, loose connections, or leaks around the valve.
• വൃത്തിയാക്കൽ: If necessary, gently wipe the exterior of the actuator with a dry or slightly damp തുണി. ഉരച്ചിലുകളുള്ള ക്ലീനറുകളോ ലായകങ്ങളോ ഉപയോഗിക്കരുത്.
• പ്രവർത്തന പരിശോധന: 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.
