This guide provides instructions for installing the Danfoss React™ M30 x 1.5 thermostatic sensor series, designed for use with Caleffi and Giacomini valve bodies. It also covers temperature limitation and shut-off procedures.
Installation
Follow these steps to install the Danfoss React™ thermostatic sensor head onto the valve body.
For Caleffi Valve Bodies
Prepare the valve body: Using a screwdriver, remove any protective cap or adapter from the Caleffi valve body. The text "Caleffi" is indicated on the valve.
Align the sensor head with the valve body, ensuring proper orientation.
Push the sensor head firmly onto the valve body until it is seated correctly.
Secure the sensor head: Use the provided tool (or a suitable alternative) to engage the locking mechanism. An inset diagram shows the tool being inserted and turned. Another inset shows a checkmark (✔️) for correct locking and a cross (❌) for incorrect locking.
Confirm installation: The sensor head should click into place. Arrows indicate the direction of engagement. Symbols for temperature (Δ) and frost protection (❄️) are shown.
The installed sensor head is shown with a dial set to a specific position (e.g., 32). A torque specification of 15 Nm is indicated for proper tightening.
For Giacomini Valve Bodies
Prepare the valve body: Using a screwdriver, remove any protective cap or adapter from the Giacomini valve body. The text "Giacomini" is indicated on the valve.
Align the sensor head with the valve body.
Push the sensor head onto the valve body.
Remove any adapter or nut from the valve body using a screwdriver.
Align the sensor head with the valve body, indicated by curved arrows showing rotation.
Push the sensor head onto the valve body, indicated by curved arrows showing rotation.
The fully installed sensor head is shown with a dial set to a specific position (e.g., 32). A torque specification of 15 Nm is indicated.
Temperature Limitation
The Danfoss React™ sensor allows for setting maximum and minimum temperature limits.
Setting Maximum Temperature
Locate the adjustment mechanism on the sensor head. An inset shows a small lever or button being manipulated.
To set the maximum temperature, turn the dial to the desired position. Position 5 is labeled "MAX".
Arrows indicate the range of adjustment for the maximum setting.
For example, to set the maximum temperature to setting 4, turn the dial to position 4. This is indicated as "e.g. MAX = 4". Arrows show adjustment.
Further adjustment to set the maximum to position 4 is shown, with arrows indicating the range.
Setting Minimum Temperature
Locate the adjustment mechanism on the sensor head. An inset shows a small lever or button being manipulated.
To set the minimum temperature, turn the dial to the desired position. Position 1 is labeled "MIN" and is associated with an asterisk symbol (*).
Arrows indicate the range of adjustment for the minimum setting.
For example, to set the minimum temperature to setting 2, turn the dial to position 2. This is indicated as "e.g. MIN = 2". Arrows show adjustment.
Further adjustment to set the minimum to position 2 is shown, with arrows indicating the range.
Shut Off Procedure
Follow these steps to shut off the valve using the thermostatic sensor head.
Ensure the sensor head is installed on the valve. The dial is typically set to a numbered position for normal operation.
Rotate the adjustment dial towards the "S" (Shut off) position. An arrow indicates the direction of rotation.
The dial is now set to "S", indicating the valve is shut off.
Additional Features
Theft Protection
The sensor head may incorporate a theft protection mechanism. Diagrams show arrows indicating how the head can be removed, potentially after setting it to a specific position (e.g., 5).
Blind Mark
A blind mark is present on the sensor head, indicated by a magnified view showing the number "3". This mark may serve as a reference point.
