Uživatelská příručka k elektrotermickému pohonu Danfoss 088H3112

1. Konec produktuview

The Danfoss 088H3112 is an electrothermal actuator designed for precise control in heating systems. This compact unit is specifically engineered for use with on/off electrical controls to operate various types of valves and manifolds, particularly in underfloor heating applications.

Mezi klíčové vlastnosti patří:

• Kompatibilita: Designed for seamless integration with Danfoss RA 2000 valve bodies.
• Operace: Functions as a normally closed (NC) device, meaning the valve is closed when power is off.
• Vizuální indikátor: Equipped with a position indicator for easy visual confirmation of the actuator's status.
• Elektrické napájení: Operates on a 230-volt power supply.
• Délka kabelu: Features a 1.2-meter electrical cable for flexible installation.

2. Bezpečnostní informace

Please read and understand all safety instructions before installing or operating this product. Failure to follow these instructions may result in property damage, personal injury, or death.

• Elektrická bezpečnost: Always disconnect power to the circuit before performing any installation, maintenance, or troubleshooting. Electrical work should only be performed by qualified and licensed personnel.
• Instalace: Ensure the actuator is installed according to local electrical and plumbing codes. Do not modify the product in any way.
• Vystavení vodě: Avoid exposing the actuator to direct water spray or submersion. While rated IP41, it is not waterproof.
• Provozní svtage: Potvrďte, že dodávka objtage matches the actuator's specified 230V.

3. Obsah balení

Po otevření balení zkontrolujte, zda jsou všechny součásti přítomny a nepoškozené:

4. Nastavení a instalace

This section outlines the general steps for installing the Danfoss 088H3112 actuator. For detailed instructions specific to your heating system, consult your system's documentation or a qualified professional.

1. Příprava tělesa ventilu: Ensure the valve body (e.g., Danfoss RA 2000) is clean and free of debris.
2. Namontujte pohon: Carefully place the actuator onto the designated connection point of the valve body. Twist or secure it according to the valve body's mechanism until it is firmly attached. Do not overtighten.
3. Elektrické připojení: Connect the actuator's electrical cable to the 230V power supply. Ensure correct polarity and secure all connections within an appropriate junction box or terminal block. Refer to local electrical codes for proper wiring practices.
4. Ověřte instalaci: After installation, visually inspect all connections to ensure they are secure.

5. Návod k obsluze

The Danfoss 088H3112 electrothermal actuator operates automatically based on the electrical signal it receives from your heating control system (e.g., thermostat, timer).

• Normálně zavřeno (NC): When there is no electrical power supplied to the actuator, it will remain in its closed position, preventing flow through the valve.
• Otevření ventilu: When the control system sends a 230V electrical signal to the actuator, it will begin to open the valve. This process typically takes a few minutes as the internal heating element warms up.
• Zavření ventilu: When the electrical signal is removed, the actuator will cool down and gradually return to its normally closed position, shutting off flow.
• Position Indicator: The red indicator on the side of the actuator provides a visual cue of its operational status. When the valve is open, the indicator will typically be extended or in a different visible position compared to when it is closed.

6. Údržba

The Danfoss 088H3112 electrothermal actuator is designed for long-term, maintenance-free operation. There are no user-serviceable parts inside the unit.

• Čištění: Pravidelně otírejte vnější část pohonu suchým, měkkým hadříkem, abyste odstranili prach a nečistoty. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
• Inspekce: Occasionally check the electrical connections for any signs of wear or loosening. Ensure the actuator remains securely mounted to the valve body.
• Vyhněte se demontáži: Do not attempt to disassemble the actuator, as this will void the warranty and may cause damage or electrical hazard.

7. Řešení problémů

If you experience issues with your Danfoss 088H3112 actuator, consider the following common troubleshooting steps:

• Actuator Not Moving/Valve Not Opening:
  • Check if the 230V power supply is active and reaching the actuator.
  • Verify that the control system (thermostat, timer) is calling for heat/flow.
  • Inspect electrical wiring for loose connections or damage.
  • Ensure the actuator is correctly mounted on the valve body.
• Valve Not Closing/Constant Heat:
  • Confirm that the control system is no longer calling for heat/flow and has removed the 230V signal.
  • Allow sufficient time for the actuator to cool down and return to its normally closed position.
  • Check for any physical obstructions preventing the valve from closing.

If these steps do not resolve the issue, contact a qualified HVAC technician or Danfoss customer support.
