Settings

You can set the required floor temperature by means of an external floor temperature controller.
The floor temperature which can be achieved depends on the floor structure and the floor covering. Observe the information in the operating and installation instructions for the floor temperature controller.

Floor temperature controller with a seven-day program
Energy saving operation is ensured by installing a floor temperature controller with a seven-day program.
Using an individually definable seven-day program means that you can adapt the temperatures to your personal requirements by specifying when the heating mat will switch on and off. The self-learning, adaptive control unit automatically determines the preheating time for timer mode. For economical operation, adjust the time it switches off so that the appliance switches off approximately half an hour before the end of use. Further information can be found in the operating and installation instructions for the floor temperature controller.

Appliance description

1. Heat conductor
2. Floor temperature sensor
3. Conduit (tube for installing the floor temperature sensor)
4. Female connection for heating conductor/cold lead
5. Cold lead (electrical power cable)
   The heating mat is a surface heating element. The heating mat comprises a heat conductor which is sewn onto a self-adhesive mesh fabric.

The heating mat is glued directly to the screed or to levelling compound (e.g. floating screed). The heat generated by the heating mat is thus transferred directly to the floor.
The required floor temperature is set via an external floor temperature controller. The floor temperature controller is equipped with a floor temperature sensor. The floor temperature sensor must be installed at heating level.
The heating mat is switched on or off according to the floor temperature set on the floor temperature controller.
The floor temperature controller takes account of heat gain, e.g. due to sunlight or lighting, and provides frost protection.
The floor temperature controller is self-monitoring. In the event of a power failure, sensor break or sensor short-circuit, the heating automatically switches off.
