Thermostatic heads serve to keep constant the ambient temperature of the room in which they are present, according to the set value. The R460 thermostatic head is equipped with liquid sensor and Clip Clap quick connection to the valve body.  VIDEO Frame the QR code with your smartphone or tablet to view the video tutorial. 028 PRODUCT CODE CONNECTION R460X001 Clip Clap  Versions and product codes The temperature variation of the environment causes a consequent variation in the volume of the liquid contained in the sensor inside the head. This volume change causes the movement of an internal mechanism with the consequent closing or opening of the valve and therefore with modulation of the flow of water that enters the heating element. When the temperature in the room is approaching the required value, the head gradually closes the valve, letting through just the minimum amount of water needed to keep the room temperature constant; this means guaranteed energy savings.  Operation R460 Datasheet 0396EN  01/2023 Thermostatic head with Clip Clap quick connection

• It is preferred that thermostatic heads are installed in the horizontal position. For vertical installation, direct influence of the radiator on the thermostatic head sensor could affect the correct measuring of the room temperature.
• In order to prevent inaccurate temperature detections, thermostatic heads should not be installed in recesses, in curtain boxes or behind curtains, and should not be exposed to direct sunlight. In these cases it is advisable to use the models with remote sensor (R462/R463). Installation on valves with thermostatic options To install the thermostatic heads on the valve body, proceed as follows: 1) Fully open the head by turning the handwheel to position . Next, pull the Clip-Clap connection towards the handwheel. AA CC BB 2) Connect the thermostatic head to the valve, making sure the valve pin (A), the small slot on the thermostatic head (B) and the Keymark symbol (C) are aligned.  WARNING. The correct slot for assembly is the smallest one. Do not try to install using the largest slots. 3) Fully close the head by turning the handwheel, the Clip Clap ring will automatically hook onto the valve. 4) Move the thermostatic head to the desired adjustment position by turning the handwheel. Removal of the thermostatic head To remove the thermostatic heads from the valve body, proceed as follows: 1) Fully open the head by turning the handwheel to position . 2) Pull the Clip Clap ring toward the handwheel. 3) Unhook the thermostatic head with a light strength.  In case it is mandatory to install the thermostatic head in vertical position, select a setting higher than the standard (see “Adjusting the temperature” table) Allowed installation positions  

Via per Alzo 39, 28017 San Maurizio d’Opaglio (NO) Italia  consulenza.prodotti@giacomini.com  +39 0322 923372 - giacomini.com Adjusting the temperature The correct adjustment position for thermostatic heads is obtained by referring to the following table, which matches the numbering on the handwheel to the corresponding room temperatures. Thermostatic head position  1 2 3 4  Temperature adjusted [°C] 8 10 15 20 25 30  NOTE. The values shown in the table refer to the optimum conditions obtained in a climatic chamber. In the room itself, these values may be altered by factors such as the type of installation, the environmental conditions, the degree of insulation in the building, and the characteristics of the radiators. If the radiator is positioned where there is cold air or draughts, the calibration temperature will not correspond to the average room temperature because the head sensor is influenced by the local temperature and therefore commands the closure of the valve too early or not at all. In these cases, the handwheel must be repositioned with the aid of a mercury thermometer positioned in the middle of the room. In example: if the head is in position 3 and the room temperature is lower than the 20 °C envisaged while the system is working, this means the valve has been prematurely closed due to local excess temperature. In this case, turn the handwheel slightly until it is halfway between number 3 and number 4. Vice versa, if the temperature is higher than the 20 °C when the head is in position 3, this means the it is positioned in a cold draught and therefore keeps the valve open. In this case, turn the handwheel until it is halfway between number 2 and number 3. If the thermostatic head is installed in rooms that are not in use, you can ensure the best energy savings by turning the handwheel to position  ( corr esponding t o the 8 ° C an ti- freeze protection temperature).  WARNING. To avoid excessive loads on the seal gasket of the thermostatic bonnet (with the resulting risk of jamming and locking) during the summer months, is is recommended to place the handwheel in the fully open position, as marked by the symbol . Handwheel opening limit / locking The handwheel limit and locking operations are carried out with the thermostatic head already installed on the valve body. 1) Turn the handwheel to position (3) and release it by pulling it forward.  WARNING. In order to prevent losses in calibration of the thermostatic head, never tamper with the position of the bulb.

• on the left of the number corresponding to the minimum desired opening. Example: fix the limiter to the right of the number 3. In this way, is possible to fully close the head, or open up to 3). 3a) A partial opening of the thermostatic head can be achieved by inserting the limiter into the cam (referring to the photos):
• on the right of the number corresponding to the maximum desired opening. Example: fix the limiter to the right of the number 3. In this way, is possible to fully close the head, or open up to 3). 3b) In order to lock the adjustment range, position a limiter to the right of the number corresponding to the maximum desired opening and a limiter to the left of the number corresponding to the minimum desired opening. This prevents the head from being either opened or closed. 2) Inside the handwheel there are two plastic limiters, to use them is necessary to extract them using a small screwdriver. Using a single limiter it is possible to partly the opening or closing of the head. Using both, it is possible to set the ends of the adjustment range, until the thermostatic head is locked in the desired adjustment position. 4) After the limiters have been positioned, return the handwheel to the initial adjustment position (3), applying sufficient pressure.  NOTE. On looking inside the head, near the bulb, a black mark should be visible. Check that this mark is always in line with the Keymark symbol on the head separator. BulB mark
