2.2 Intended use
The single room temperature controller is used to control the temperature in rooms with an underfloor heating system (heat/cool). The product may only
be used to program the temperature reduction and the additional pump running time. Any use other than the application explicitly permitted in these
operating instructions is not permitted and causes hazards. Verify that the product is suitable for the application planned by you prior to using the product.
In doing so, take into account at least the following:
• All directives, standards and safety regulations applicable at the installation site of the product

4.2 Function
The single room temperature controller is used to control the temperature in rooms with an underfloor heating system (heat/cool).
The product features a hundred year calendar. The display shows the date, time and day of the week.
The product features two independently programmable switching channels for temperature reduction. A total of nine programmable memory blocks are
available. The additional pump running time can be set via the product. The product has a valve and pump protection function.
The interval function sends signals to the actuators at regular intervals so that the thermostat valves open automatically; the function helps to keep the
spindle from blocking in the valve body.
4.3 Approvals, conformities, certifications
The product complies with:
• EMC Directive (2014/30/EU)
• RoHS Directive (2011/65/EU)
