- If you choose floor heating. Wood or other. If you choose other, the question is asked if there is a floor sensor installed
Temp.to control
- Floor or room sensor.
  If you choose floor heating, we advise you to control the floor temperature by using the floor sensor.
Summary
- Containing the current settings.
Temperature
- Program the comfort temperature of your choice for a heating period. Standard temperature for a “different heating system is programmed at 21 degree Celsius and 23 degree Celcius for a floor heating system.
Overview wizard
- Containing the selected heating periods according the standard program.
Slow heating
- It is possible to choose this option (Ref Mode selection point 7 slow start-up).

Mode selection

Automatic mode:
According to the weekly program, the thermostat automatically adjusts the set temperature operation.

Temporary temperature:
To temporarily override the temperature in the automatic program. The override will operate until the next automatic event.

Manual mode:
The thermostat runs continuously according to the set temperature.

OFF:
Manually turn off all functions of the thermostat. When you want to reactivate the thermostat, just select the mode you want.

Anti-frost mode:
Range is set from 41°F to 59°F(5°C -15°C） in this mode. This mode is used when you want to keep your room at a lower temperature when you are on vacation.

Timer:
Use this mode when you are on holidays etc.The thermostat will be off for the chosen period. After this period, the thermostat will return to the standard or the custom time settings.

Slow heating:
To be used for new floors only. The thermostat will slowly raise the temperature of the floor over a 20 day period. After this period the thermostat automatically starts the standard or the custom time programme. If you need to stop or restart the slow start up mode, press the left button.

Temperature settings:
You can change the programmed temperature (comfort or set back ). Attention: In the case of floor heating, it is not necessary to program the setback temperature.The setback temperature is controlled by the thermostat automatically.

Programming:
The comfort temperature and times can be changed in this menu.

Standard program:

Monday–Sunday

Period 1| 06:00-09:00| 23℃
Period 2| 17:00-22:00| 23℃

Custom week program: Push the button to confirm the function ‘program’.

You enter the screen with the standard settings schedule.

Press button,‘standard’ appears on the display.

Press button,‘standard’ is selected.

Press button select ‘custom’. confirm this with button.

Press / button return to the screen of programmed times.

Now you can confirm the symbol by pushing the right button.You can adjust one or two periods a day.

If you want to program the same time periods on different days, use the easy copy-and-paste function.

Consumption: The thermostat calculates the average time it has been switched on allowing you to monitor your energy consumption. The total switched on time is by percentage (%) shown over the last 30 and 365 days.

Calculate consumption:

30 days: 24 hours x 30 days x total installed power x % = energy consumption
365 days: 24 hours x 365 days x total installed power x % = energy consumption

Example:
The thermostat gives a percentage of 26% over 30days.

The power installed in the floor is 700 Watt.

24 hours x 30 days = 720 hours.
720 hours x 0.7 kW = 504 kWh
26% of 504 kWh = 131 kWh.

Child lock:
The thermostat is locked with this function.Mode and menu settings cannot be used.To switch the child lock function on or off, push the right key and hold it for a few seconds. When the child lock is switched on, a padlock appears on the display.

Advanced functions: The thermostat provides advanced settings to suit a range of special situations which are normally set by a technician during initial installation.

Heating system.
1. Type of heating system (floor heating or other heating)
2. Surface material: wood or other
3. Temp.to control: floor or room

These settings can also be changed using the start up wizard.

Calibration.
A correction can be made here on the temperature in the display and the measured room temperature. Consult your supplier before changing calibration setting.Setpoint range: ±5°C.
Intelligence.
Switch the intelligent function on or off.
The thermostat has a self thinking and adaptive system. This function enables the thermostat to calculate when it needs to switch on so that the required temperature is reached at the set time. (i.e. if the set time is 08:00, the thermostat will switch on earlier so that the set temperature is reached at 08:00).
Difference.
Example: Set the value to 1°C.
The difference between switch on and off period during heating time.
The thermostat starts when the room temperature is 1°C lower than set temperature and stops when the room temperature is 1°C higher than the set temperature.
Pilot wire.
Can be used to operate the thermostat through an external source.This can be a central source or a smart home system. This function can be turned on or off.
Sensor type.
Gives the possibility to adjust the sensor value. This is not required in a standard situation.
Consult your supplier before changing sensor type.
Open window.
This function only works when room sensor or both sensors is selected. The thermostat with this function will shut off automatically for 15 min when the window opens, as it can detect that the room temp plummets.
Factory defaults.
All parameters are restored to default value.You need to right-click and hold down for 5 seconds to perform this operation

Explanation of text / Symbols

Set back mode：
The setback mode is when the thermostat ‘sets back’ to a lower temperature during the off time periods. This is the most economical and efficient way to achieve the best energy consumption.

Floor temperature limiter：
Some floor coverings must be limited at a certain maximum temperature (for example wooden floors). When the option ‘Wooden’ is selected (in the start up wizard), the floor will not exceed 28ºC.
