This document provides essential instructions for the installation, temperature limitation, and security setup of the Danfoss Aero RA click thermostatic sensor. It covers standard installation, BIV installation, uninstallation, and how to restrict temperature ranges or enable theft protection.
Installation
The sensor features a click-on mechanism for easy mounting:
- Ensure the sensor is set to the maximum position.
- Align the sensor with the valve body.
- Press the sensor firmly onto the valve until you hear a distinct click, indicating it is securely locked in place.
BIV Installation
For BIV (Built-in Valve) configurations, follow the same click-on procedure: remove the protective cap, align the sensor, and press until it clicks onto the valve interface.
Uninstallation
To remove the sensor, firmly grip the base and pull it away from the valve body while ensuring the locking mechanism is released.
Temperature Limitation
You can restrict the temperature range to prevent overheating or overcooling:
- Maximum Limitation: Use the provided limiter tool to set a maximum temperature stop. Insert the tool into the slot, adjust to the desired maximum value (e.g., 4), and secure it.
- Minimum Limitation: Similarly, use the limiter tool to set a minimum temperature stop by inserting it into the corresponding slot and adjusting to the desired minimum value (e.g., 2).
Theft Protection
To prevent unauthorized removal of the sensor:
- Locate the theft protection slot on the side of the sensor.
- Insert the security clip or screw mechanism as shown in the diagrams to lock the sensor onto the valve.
- To remove the sensor later, use a screwdriver to disengage the security lock before pulling the sensor off.
