2. Installation Note: Assignment of Room Thermostats to Master Controller should be within a distance of 1.5 m. Activate Install mode on Master Controller (fig. 1) • Use the menu selection button to select the Install mode. Install LED flashes. • Activate Install mode by pressing OK. Install LED goes ON. Activate Install mode on room thermostat • Press the push button . LED and flicker during communication. Select output on Master Controller • All available output LEDs on Master Controller light up, and the first one flashes. • Press output selection button to select desired output (flashes). Accept with OK . • All output LEDs go OFF. Selected output stays ON shortly. Room thermostat installation status • Satisfactory: LED goes OFF. • Not satisfactory: LED flashes 5 times. Note: A room thermostat can be assigned to several outputs if needed by repeating the installation process.

Setting of room temperature 1. Make sure actual room temperature is shown in the display. 2. Press the up/down selector to set the desired room temperature value. SET is shown in the display. 3. When releasing the up/down selector the display returns to actual temperature. Note: The thermostat regulates the floor heating system according to room temperature set point, within the maximum and minimum limitations defined for the floor surface temperature. Room temperature limitation 1. Make sure actual room temperature is shown in the display. 2. Press the push button until SET MAX is shown in the display. 3. Press the up/down selector to set the maximum room temperature limitation. 4. Press the push button shortly, SET MIN is shown in the display. 5. Press the up/down selector to set the minimum room temperature limitation. 6. Press the push button shortly and the actual floor surface temperature is shown in the display.

Floor surface temperature limitation 1. Ensure actual floor surface temperature is shown in the display illustrated by . 2. Press and hold the push button until SET MAX is also shown in the display. 3. Press the up/down selector to set the maximum floor surface temperature limitation. 4. Press the push button shortly, SET MIN is also shown in the display. 5. Press the up/down selector to set the minimum floor surface temperature limitation. IMPORTANT! As heat emission from the floor may vary slightly depending on floor covering - and thereby cause inaccurate temperature measurement - it may be necessary to adjust the setting of max. and min. floor surface temperatures accordingly. It is important always to follow recommendations from the floor manufacturer regarding max. floor surface temperature. It is recommended always to include mixing shunt for floor heating circuits in order to ensure optimal flow temperature. - In addition to minimised energy consumption, correct setting of the flow temperature will eliminate the risk of excessive heat transfer to the floor.

4. Transmission Test Initiate transmission test on room thermostat (fig. 1) • Press the push button . • LED goes ON. Link test is satisfactory • LED goes OFF. Link test is unsatisfactory • LED flashes 5 times. No Link connection to room thermostat • Try to relocate room thermostat in the room. • Or install CF-RU Repeater Unit and locate between Master Controller and room thermostat. Note: When connected to a room thermostat, the Master Controller output LED(s) flash(es) during Link test.

5. Mounting Placing a room thermostat (fig. 3) • A room thermostat should be placed in accordance with fig. 3. IMPORTANT! Wherever possible, a room thermostat should be installed at a place where the effect of sunlight, strong artificial light (e.g. halogen spotlight), draught, other heat-emitting equipment (e.g. TVs) etc. is avoided. Please note that no furniture, rugs etc. should be permanently placed within the area of the InfraRed Floor Sensor as shown in fig. 3.
6. Uninstallation Activate Uninstall mode on Master Controller (fig. 1) • Use the Menu selection button to choose the Uninstall menu. Uninstall LED flashes. • Activate Uninstall mode by pressing OK . Uninstall LED goes ON. Deselect output on Master Controller • Select output to be removed by output selection button . • Remove flashing output with OK .
