1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Buderus WK 7300-00.500 Thermostatic Head. Please read these instructions carefully before installation and retain them for future reference. Correct use ensures optimal performance and longevity of the product.
2. Product Overview
The Buderus WK 7300-00.500 is an angled thermostatic head designed for precise temperature control in rooms equipped with radiators. It features a liquid-filled sensor for stable and accurate regulation of room temperature by controlling the flow of hot water through the radiator.
Key Features:
- Angled Design: Optimized for mounting on radiators with an M30 x 1.5 threaded connection.
- Integrated Sensor: Ensures accurate temperature detection and control.
- Reversible Mounting: Can be installed on either the left or right side of the radiator valve.
- Liquid-Filled Thermostat: Provides stable and responsive control behavior.
- White Scale Cover: Clear and easy-to-read temperature settings.
3. Setup and Installation
Safety First: Before beginning installation, ensure the heating system is depressurized and cooled down to prevent injury from hot water or steam. If you are unsure about any steps, consult a qualified heating technician.
Installation Steps:
- Prepare the Radiator Valve: Ensure the existing thermostatic valve body on your radiator has an M30 x 1.5 threaded connection.
- Remove Old Head (if applicable): If replacing an old thermostatic head, carefully unscrew it from the valve body.
- Position the Thermostatic Head: Place the Buderus WK 7300-00.500 onto the valve body. The head is reversible, allowing for left or right mounting to suit your radiator's orientation.
- Secure the Head: Hand-tighten the threaded ring of the thermostatic head onto the M30 x 1.5 connection of the valve body until it is firm. Do not overtighten.
- Check for Stability: Ensure the head is securely attached and does not wobble.
4. Operating Instructions
The Buderus WK 7300-00.500 Thermostatic Head allows you to set your desired room temperature by rotating the control knob. The scale is typically marked with numbers and symbols:
- Snowflake Symbol (❄): Frost protection setting. This setting prevents the room temperature from dropping below approximately 6°C (43°F), protecting pipes from freezing.
- Numbers (1-5): These numbers correspond to approximate room temperatures. Each increment typically represents a change of about 4°C (7°F).
- Setting 1: Approximately 12°C (54°F)
- Setting 2: Approximately 16°C (61°F)
- Setting 3: Approximately 20°C (68°F) - Recommended comfort setting
- Setting 4: Approximately 24°C (75°F)
- Setting 5: Maximum heat, approximately 28°C (82°F)
- Sun Symbol (☀): Often indicates a higher comfort setting, typically around 20-21°C (68-70°F), similar to setting 3.
To adjust the temperature, simply rotate the control knob until the desired number or symbol aligns with the indicator mark on the head.
5. Maintenance
The Buderus WK 7300-00.500 Thermostatic Head requires minimal maintenance to ensure continued efficient operation.
- Cleaning: Wipe the exterior of the thermostatic head with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the surface.
- Function Check: Periodically check that the control knob turns smoothly and that the radiator heats up and cools down as expected when adjusting the setting.
- Avoid Obstructions: Ensure that curtains, furniture, or other objects do not obstruct the thermostatic head, as this can interfere with its ability to accurately sense room temperature.
6. Troubleshooting
If you experience issues with your thermostatic head, consider the following common problems and solutions:
- Radiator Not Heating:
- Ensure the thermostatic head is set to a temperature higher than the current room temperature.
- Check if the valve pin is stuck. Remove the thermostatic head and gently press the pin in the valve body. It should move freely. If stuck, it may need lubrication or professional attention.
- Verify that the central heating system is operational and that other radiators are heating.
- Radiator Always Hot (even on low setting):
- Ensure the thermostatic head is correctly installed and tightened.
- The valve pin might be stuck in the open position. Try the method described above to free it.
- The thermostatic head might be faulty and require replacement.
- Inconsistent Room Temperature:
- Check for drafts or obstructions around the thermostatic head that could affect its temperature sensing.
- Ensure the heating system is balanced.
If these steps do not resolve the issue, contact a qualified heating technician.
