Thermostatic heads serve to keep constant the ambient temperature of the room in which they are present, according to the set value. The R469H thermostatic head is equipped with liquid sensor and connection to the valve body with threaded ring nut M30 x 1,5 mm. 028 PRODUCT CODE CONNECTION R469HX001 Threaded ring nut M30 x 1,5 mm  Versions and product codes  NOTE. The thermostatic head is equipped with an indication in Braille of the number 3 on the knob, and the + and - signs are also raised, so the adjustment can also be made by blind and/or partially-sighted people. 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 R469H Datasheet 0845EN  01/2023 Thermostatic head with threaded connection M30 x 1,5 mm

• 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. 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) Unscrew the threaded ring nut. 3) Unhook the thermostatic head with a light strength. 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 . 2) Insert the thermostatic head on the hexagon of the valve body and turn the ring nut to tighten it. 3) The head is now installed to the valve and can be moved to the required adjustment position by turning the handwheel.   

When it is necessary to return the limiter ring to the default position: 1) position the indicator (T) in correspondence to the word “reset”. 2) set position 3 on the thermostatic head in correspondence to the word the word “reset”. T 1) Turn the handwheel to the position that you want to partially limit/lock , and disconnect the limiter ring with the aid of a screwdriver. Example: in this figure, you want to lock/partially limit it to position 3. LIMITER LIMITER RINGRING 2) Rotate the limiter ring. Using the “T” notch as a reference (see figure), connect the ring in line with one of the 3 icons on the back of the handwheel: 1.  2. 0 3. lock TT 3a) Achieving partial opening/closure of the thermostatic head:

• in position 0 the required position is limited to 0 (shut-off). Example: fix the handwheel in position 3 and the limiter ring in position 0 . In this way, the head can be fully closed, or opened up to 3.
• in position  the required position is limited to  (fully open). Example: fix the hadnwheel in position 3 and the limiter ring in position  . In this way, the head can be fully opened, or closed as far as 3. 3b) Locking the adjustment range:
• in the lock position, the adjustment is locked in the required position. Example: fix the handwheel in position 3 and the limiter ring in the lock position. In this way, the head is locked in position 3 and cannot be adjusted. 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.  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). In case of radiator maintenance, is possible to use the thermostatic head “shut off” function (position “0”). The mechanical closure allows to shut off the radiator valve without having to disassemble the thermostatic head and reassemble the manual handwheel.  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 .
