  • Page 46 User menu A thermometer may indicate temperature fluctuations more slowly or rapidly than the RC35. B so never calibrate the RC35 when your heating system is in the process of cooling down or heating up. 1. Open the User menu.

  • Page 47: Information For Setting The Rc35

    • Room temperature control: in this case, the RC35 must be mounted in a room that is representative of your home. The RC35 records the room temperature in this “reference room”.

  • Page 48: Tips For Energy Efficiency

    • Ventilate your home wisely: Leave the windows wide open for a few minutes rather than leaving them slightly open all the time. • While ventilating rooms, set the RC35 to night mode. Do this by pressing the night button.

  • Page 49: Troubleshooting

    Why does a separate thermometer not match the room temperature set in the RC35? Various different factors influence the room temperature. If the RC35 is installed on a cold wall, it will be influenced by the cold temperature of that wall. Conversely, it will be influenced by the heat from a fireplace or chimney, if it is installed in a warm part of the room.
