Press the menu button (10) in the bottom right-hand corner.
This will show the setup display. Press the orange (calendar) button.
This will show you the date and time. If the date or time are wrong then use the up and down buttons to set the correct date and time. Then press the Tick button.

Press the towel rail button (3). Every time you press it it will cycle through its different modes:

• towel rail on a red background: OFF
• towel rail on a white background: ON
• towel rail on a white background with an arrowed circle around it: The UFH is controlled by the heating timer schedule.
• towel rail on a white background with a 1: On for 1 hour
• towel rail on a white background with a 2: On for 2 hours
• towel rail on a white background with a 4: On for 4 hours

When the towel rail is switched on or off you might hear a click. This is the relay inside the box stitching the power on or off. Also the towel rail symbol (6) will change.

Press the underfloor heating button (2). The picture shown on the button tells you what the UFH is doing.

1. a plant leaf means it's in ECO mode.
2. a clock means it's in timer mode.
3. a pointing finger means it's in manual mode.
4. an armchair means it's in comfort mode.

To get you started, keep the UFH in ECO mode normally, this means it will only come when it gets really cold, i.e. below 16C in your apartment.
One hour before you want to use the shower/bath put the UFH into comfort mode i.e. the armchair. This will set the temperature to 24C. Before you go in or when you come out set it back to ECO mode.
When the UFH heating is one the symbol (5) will show.

For more complicated stuff you will need to read the user manual.
