Model: 2TRV HEAD
ആമുഖം
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.

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.
പരിമിതമായ താപനില പരിധി:
ഉയർന്ന പരിധി:
- 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.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ
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.
- താപനില ക്രമീകരണം: 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.

മെയിൻ്റനൻസ്
The Myson TRV head is designed for long-term, maintenance-free operation. However, occasional checks can ensure optimal performance:
- വൃത്തിയാക്കൽ: Wipe the exterior of the head with a soft, damp തുണി. ഉരച്ചിലുകളുള്ള ക്ലീനറുകളോ ലായകങ്ങളോ ഉപയോഗിക്കരുത്.
- സീസണൽ പരിശോധന: 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.
- തടസ്സങ്ങൾ ഒഴിവാക്കുക: Ensure curtains, furniture, or other objects do not obstruct the thermostatic head, as this can affect its ability to accurately sense room temperature.
