Zavedení
This manual provides essential information for the installation, operation, and maintenance of your Myson Standard Thermostatic Radiator Valve Replacement Head (TRV 2 WAY). This product is designed as a direct replacement head for existing Myson TRV 2-way thermostatic radiator valves. Please note that this product includes the head only; the valve body is not included. It is also interchangeable with the Myson 'Contract' thermostatic head, which has a similar appearance but lacks red markings and features a black bottom section with a white triangle.

- Set the arrow on the replacement head to the fully open position (indicated by a black dot or maximum setting).
- Engage the sensor head firmly onto the valve body.
- Zašroubujte knurled ring securely to the valve body by hand until it is finger tight. Avoid overtightening.

Use of Locking Pins (Where Provided)
Some Myson TRV heads come with metal locking pins to set minimum and maximum temperature limits. Refer to Figure 2 for visual guidance.
Locking a Specific Level:
- Set the valve to the desired temperature level.
- Insert the first locking pin in line with the 'circular black' marking.
- Insert the second locking pin in line with the 'black dot' marking.
Limitní rozsah teplot:
Vysoký limit:
- Set the valve temperature to the highest required level.
- Insert the first locking pin in line with the 'black dot' marking.
Low Limit:
- Set the valve temperature to the lowest required level.
- Insert the second locking pin in line with the 'circular black' marking.

Návod k obsluze
The Myson TRV head allows you to control the heat output of your radiator by sensing the room temperature and adjusting the flow of hot water through the valve. The head features numerical settings and symbols to indicate temperature levels.
- Nastavení teploty: Rotate the head clockwise or counter-clockwise to select your desired room temperature. Higher numbers typically correspond to warmer settings.
- Frost Protection (*): Setting the head to the snowflake symbol (*) will activate frost protection, maintaining a minimum temperature (typically around 7°C) to prevent pipes from freezing.
- Fully Open Setting: The highest numerical setting or a specific symbol (often a black dot or 'MAX') indicates the fully open position, allowing maximum heat output from the radiator.

Údržba
The Myson TRV head is designed for long-term, maintenance-free operation. However, occasional checks can ensure optimal performance:
- Čištění: Otřete vnější část hlavy měkkým hadříkemamp tkanina. Nepoužívejte abrazivní čisticí prostředky nebo rozpouštědla.
- Sezónní kontrola: Before the heating season, ensure the head rotates freely through its full range of settings. If the radiator is cold when the valve is open, gently press the pin on the valve body to ensure it is not stuck.
- Vyhněte se překážkám: Ensure curtains, furniture, or other objects do not obstruct the thermostatic head, as this can affect its ability to accurately sense room temperature.
Odstraňování problémů
