Description of the parameters

Parameter 2 – Selecting the preset time programs

• Week program 1 (factory setting, 2 setpoints):
  Mo – Su (1 – 7) at home all day
  This time program is described in Section 8.
• Week program 2 (6 setpoints):
  Mo – Fr (1 – 5) lunch break at home
  Sa – Su (6 – 7) like Week program 1

Setpoint	Time	Temperature
1	6:00 – 9:00	20°C (Comfort temperature 1)
2	9:00 – 12:00	16°C (Setback temperature)
3	12:00 – 13:00	20°C (Comfort temperature 1)
4	13:00 – 17:00	16°C (Setback temperature)
5	17:00 – 22:00	22°C (Comfort temperature 2)
6	22:00 – 6:00	16°C (Setback temperature)

• Week program 3 (4 setpoints):
  Mo – Fr (1 – 5) part-time work
  Sa – Su (6 – 7) like Week program 1
  

Setpoint	Time	Temperature
	6:00 to 9:00	20°C (Comfort temperature 1)
	9:00 to 13:00	16°C (Setback temperature)
	13:00 to 22:00	22°C (Comfort temperature 2)
	22:00 to 6:00	16°C (Setback temperature)

Parameter 3 – Backlight
The display has a backlight for reading the information.

Parameters 5 to 7 – Window function
In order to save energy, the radiator controller closes the radiator valve when you open a window resulting in a large drop of the temperature.
When you close the window so that the temperature rises the radiator controller opens the radiator valve again.
If you should ever forget to close the window, the radiator controller opens automatically after the set time in order to ensure frost protection.

Parameter 8 – Valve stroke
The radiator controller operates with the optimum valve stroke set in the factory.
If the entire valve stroke is to be used or if the valve does not open completely, activate the full-stroke mode.

Parameter 9 – Temperature representation in the display

Parameter 12 – Optimization function
Without optimization (factory setting) the radiator controller begins to heat up the room or lower the temperature at the programmed time.
For example, in order to have a warm bathroom at 7:00, the setpoint has to be brought forward. Otherwise the room only starts heating at 7:00. However, the advanced setpoint may lie too early so that heating is started far earlier than necessary.
With optimization the radiator controller calculates when to open the valve in order to achieve the desired temperature at the set time.

Parameter 13 – Temperature offset
Since the radiator controller measures the room temperature in the area of the radiator, it is possible that this temperature deviates from the temperature measured at a different point in the room. If, for example, 20°C is measured in the room and 21.5°C at the radiator, this effect can be compensated by an offset of –1.5°C.

Parameter 15 – Display of the valve position
When this parameter is activated (setting "1"), the calculated valve position (0 to 100% opened) is displayed momentarily.
The main display is shown again after approx. 3 minutes or when the AUTO button is pressed.

Parameter 16 – Valve exercise day
If the radiator valve has not been opened once completely within the period of 2 weeks, a self-test (forced operation) is carried out. The radiator controller opens the radiator valve briefly on the subsequent Monday (factory setting) in order to prevent seizing.
The weekday for valve protection can be selected freely

Parameter 17 – Window open function

Further functions
