Product Overview
The Hansgrohe ShowerSelect Comfort S flush-mounted thermostat is designed to enhance your bathroom experience with its sleek design and intuitive functionality. This thermostat controls two water outlets, providing precise temperature and flow management for your shower or bath. Its ultra-flat construction offers more space and a modern aesthetic.
Installation Instructions
The ShowerSelect Comfort S thermostat requires flush-mounted installation. A basic body, specifically the Hansgrohe iBox universal 2 (#01500180), is necessary for proper installation. Ensure all plumbing connections are secure and watertight before final assembly. Professional installation is recommended to ensure correct functionality and compliance with local building codes.

Operating the Thermostat
Water On/Off (Select Function)
The thermostat features large, intuitive buttons for turning water on and off. Press the upper or lower button to activate the corresponding water outlet (e.g., head shower or hand shower). Both functions can be used simultaneously if desired.

Temperature Control
The thermostat maintains a constant desired water temperature. To adjust the temperature, rotate the central handle. The SafetyStop feature prevents accidental scalding by requiring a deliberate action (usually a button press on the handle) to increase the temperature above 40°C.

Maintenance and Care
To ensure the longevity and appearance of your Hansgrohe thermostat, regular cleaning is recommended. The 'Quick Clean' feature simplifies maintenance. Use mild cleaning agents and a soft cloth. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the chrome finish. The thermostat also supports thermal disinfection for hygiene purposes.

Troubleshooting
If you experience issues with your thermostat, first check the water supply to your home. Ensure the iBox universal 2 basic body is correctly installed and accessible. Verify that the temperature and flow controls are set appropriately. For persistent problems such as inconsistent temperature, low flow, or leaks, it is recommended to consult a qualified plumber or contact Hansgrohe customer support for assistance.
