Page 9: How The Thermostat Works
How the thermostat works This section describes all you need to know about how the thermostat works and how you set it. On/off switch Temp. control Turning off and on The heating is not controlled in stand- by mode. Depress the on/off switch for a second to access stand by mode. - Page 10 Control functions The thermostat can regulate the tempera- ture in three different ways. This enables the comfort temperature and any flooring temperature requirements to be combined. How the settings are adjusted is descri- bed on the next page Floor thermostat (F) - A sensor in the floor measures the temperature and then regu- lates the heating accordingly.
- Page 11 The adjustment of the regulating function, must be done by a qualified electrician. The knob and the front first have to be removed. Disconnect from power supply before removing. Then slide the control to the required position using a small screwdriver. The overheating protection is adjusted here.
- Page 12 Temperature Regulating function The thermostat regulates the temperature via a sensor in the floor that measures the temperature and regulates the heating accordingly. Set the temperature required Change the floor temperature by turn- ing the knob. Min. position on the con- trol corresponds to 10 °C, max.
- Page 13 Key lock button When you have found a suitable set- ting for the temperature you can lock the knob. This prevents the control being changed accidentally. See illustration below. First remove the knob. Then move the two plastic parts so that they define the interval required.
