Danfoss Thermot 088H3220 Thermal Actuator Instruction Manual

1. ຜະລິດຕະພັນເກີນview

1.1 ລາຍລະອຽດທົ່ວໄປ

The Danfoss Thermot 088H3220 thermal actuator is designed for precise control in heating and cooling systems. It operates silently and is maintenance-free. This actuator is specifically engineered to open and close valves on heating circuit distributors for surface radiators and surface cooling systems. It functions as a normally closed (NC) device, meaning it is closed when no power is supplied.

1.2 ລັກສະນະທີ່ສໍາຄັນ

• Normally Closed (NC) Operation: The valve remains closed without power.
• M30 x 1.5 mm Threaded Connection: Ensures broad compatibility with various valve types.
• Visual Operating Indicator: Provides clear status of valve position (open or closed).
• First-Open Function: Facilitates initial system setup and filling.

1.3 ຜົນປະໂຫຍດ

• ການອອກແບບກະທັດຮັດ: Allows for installation in confined spaces.
• ການບໍລິໂພກພະລັງງານຕໍ່າ: ການດໍາເນີນງານທີ່ມີປະສິດທິພາບດ້ານພະລັງງານ.
• Easy Function Control: Simple and reliable operation.
• Ideal for Renovation Projects: Adaptable to existing systems.

2. ການຕິດຕັ້ງ

2.1 ຄໍາແນະນໍາການຕິດຕັ້ງ

The Danfoss Thermot 088H3220 actuator features an M30 x 1.5 mm threaded connection for direct mounting onto compatible valves. Ensure the valve is clean and free of debris before attachment. Hand-tighten the actuator onto the valve until secure. Do not overtighten.

2.2 ການເຊື່ອມຕໍ່ໄຟຟ້າ

This actuator requires a 230 V AC power supply. A 3 A fuse is necessary for protection within the electrical circuit. Connect the actuator in combination with a suitable room temperature controller (e.g., Danfoss RET, FHW, TP series, or CF radio-controlled system, Link system, and other leading manufacturers). Always ensure electrical connections are made by a qualified professional and comply with local electrical codes.

2.3 ຄວາມເຂົ້າກັນໄດ້

The M30 x 1.5 mm threaded connection ensures compatibility with a wide range of valves. Known compatible manufacturers include:

• Heimeier HKV
• Oventrop HKV
• KaMo HKV
• Artiga HKV
• Cosmo/Cosmoroll HKV
• Roth HKV
• Artiga/Strawa HKV
• Empur HKV
• Herotec HKV
• Protection HKV
• Zewotherm HKV

For compatibility with other manufacturers, please consult their documentation or contact Danfoss support.

3. ການດໍາເນີນງານ

3.1 Functional Overview

The Thermot thermal actuator works in conjunction with a room temperature controller. When the controller signals a demand for heat (or cooling), the actuator receives power, causing its internal element to expand and slowly open the valve. When the demand is met, power is removed, the element contracts, and the valve slowly closes. The full movement of the valve spindle takes approximately 3 minutes.

3.2 Visual Indicator

The actuator is equipped with a visible position indicator. This indicator allows you to visually confirm whether the valve is in an open or closed position, providing immediate feedback on the system's status.

4. ບໍາລຸງຮັກສາ

The Danfoss Thermot 088H3220 thermal actuator is designed for maintenance-free operation. No regular servicing, lubrication, or cleaning of the internal components is required. Ensure the external surfaces are kept clean and free from dust or debris to prevent obstruction of the visual indicator.

5. ການແກ້ໄຂບັນຫາ

5.1 ຕົວກະຕຸ້ນບໍ່ຕອບສະໜອງ

• ກວດສອບການສະຫນອງພະລັງງານ: Ensure the actuator is receiving the correct 230 V AC power supply.
• ກວດ Fuse: Inspect the 3 A fuse in the electrical circuit for any signs of damage or tripping.
• ການເຊື່ອມຕໍ່ຕົວຄວບຄຸມ: Confirm that the actuator is correctly wired to the room temperature controller.
• ການທໍາງານຂອງຕົວຄວບຄຸມ: Ensure the room temperature controller is operating correctly and sending the appropriate signal to the actuator.

5.2 Valve Not Opening/Closing Fully

• ສິ່ງກີດຂວາງທາງກາຍ: Check for any physical obstructions around the valve spindle that might prevent full movement.
• ການຕິດຕັ້ງທີ່ປອດໄພ: Ensure the actuator is securely mounted and the M30 x 1.5 mm threaded connection is tight.
• Movement Time: Note that the full valve spindle movement takes approximately 3 minutes. Allow sufficient time for the actuator to fully open or close the valve.
