Controls and display
Temperature Display and Setting
The thermostat usually displays the room temperature. To view the set (desired) temperature, press either of the AV buttons once. The set temperature is displayed for5 seconds. To set a new temperature, press one of the AV buttons repeatedly until the desired temperature is displayed. To scrol faster, press and hold the button.
Backlight
The display illuminates for 5 seconds when the backlight button is pressed. When either of the AY buttons is pressed, the display illuminates for 10 seconds. The set temperature appears for the first 5 seconds, then the room temperature is displayed.
On/Standby Switch
You can set the thermostat to Standby to cut power to the heating system when it is not in use e.g. in summer. The thermostat screen becomes blank but all settings are saved.

To select the F Mode, connect the floor temperatureTo select the AF Mode, proceed as follows: Connect the floor temperature sensor. Place the switch in the F position. If the thermostat displays Er, the sensor is improperly connected or damaged. If the thermostat displays a temperature reading, place the switch in the AF position. To select the A Mode, place the switch in the AF position but do NOT connect the floor temperature sensor.
Floor temperature limits AF mode onlyThe minimum and maximum floor temperature limits are available only if the temperature control mode is AF. If the floor temperature drops below the minimum limit or rises above the maximum limit, the thermostat will turn the heating On or Off respectively, regardless of the ambient temperature, to maintain the floor temperature within the set limits.
NOTE
The desired ambient temperature might not be attainable if the maximum floor temperature is set too low. The minimum and maximum floor temperature limits are factory-set at 10 °C (50 °F) and 28 °C (82 °F) respectively. To modify the limits, proceed as follows:
WARNING
To avoid damaging your floor, follow your floor supplier’s recommendations regarding floor temperature limits. Switch the thermostat to Standby. While pressing either button , up and down switch the thermostat back to On to access the floor temperature limit settings. Press the Backlight button briefly to switch between minimum and maximum floor temperature settings. Press the up and down buttons to set the desired limit. Press the Backlight button for 3 seconds to save your modifications. After the data are saved, the thermostat displays the current temperature.
NOTE
Your modifications are automatically saved if no button is pressed for 60 seconds.
