controller automatically returns to the last
operating mode selected!

Info
The controller works with the set operating times and
the corresponding different reference flow tempera-
ture values only in the automatic mode.
Menu 4.1 Heat circuit
Auto = Automatic/Normal mode using the set times.
Continous Day = The set values for day mode are used.
Continous Night = The set values for night mode are used.
Reference Value = Fixed flow temperature regardless of the outdoor temperature. The
desired flow temperature has to be set in menu 4.3.
14 day reference value = Specific fixed flow temperatures can be set for the next 14
days in menu 4.4. After 14 days, the reference temperature of the 14th day is used
until the operating mode is changed.
Off = Heating circuit is switched off (except Frost protection)
Settings range: Auto, Continous day, Continous night, Reference value, 14 day refe-
rence, Off / Default: Automatic
Menu 4.2 Manual
In Manual mode the individual relay outputs and the connected consumers can be
checked for proper functioning and correct assignment.
The operating mode "Manual" may only be used by specialists for brief function
tests, e.g. during commissioning!
Function in manual mode:
The relays and thus the connected consumer are switched on and off by pressing a key,
with no regard to the current temperatures and the parameters which have been set.
At the same time, the current measurement values of temperature sensors are also
shown in the display for the purposes of function control.

Menu 4.3 Heat circuit reference
If operating mode "Reference value" is selected, (Menu 4.1), the reference flow tempe-
rature has to be set here, regardless of the curve/outdoor temperature.
Settings range: 10 °C to 75 °C, Default: 30 °C
Menu 4.4 14 day reference
If operating mode "14 day reference value" is selected (Menu 4.1), the reference flow
temperature for each of the 14 days can be set here.
In the first menu 4.4.1 the starting time of the program is shown. To start the program,
hit restart.
Set parameters for the heating circuit
Hitting "restart" again will reset the 14 day reference program and start it at day 1.
HC (HEATING CIRCUIT) SETTINGS, MENU 5
Menu 5.1 S/W Day = Summer/Winter changeover
in daytime mode
5. Exit settings
If this value is exceeded at outdoor sensor during the
5.1 S/W day 18ºC
daytime mode times, the controller automatically swit-
5.2 S/W night 12ºC
ches the heating circuit off = Summer mode.
▲ ▼
If the outdoor temperature drops below this value, the
Info
heating circuit is switched on again = Winter mode.
Setting range: from 0°C to 30°C / default setting: 18°C
In addition to the operating times in normal daytime operation, this setting is
also valid for times with activated comfort temperature boost.
Menu 5.2 S/W Night = Summer/Winter changeover in nighttime mode
If this value is exceeded at outdoor sensor during the nighttime mode times, the control-
ler automatically switches the heating circuit off = Summer mode.
If the outdoor temperature drops below this value, the heating circuit is switched on
again = Winter mode.
Settings range: 0°C to 30°C / Default: 12°C
Menu 5.3 Curve = Slope of the characteristic heating curve
The characteristic curve is used to control the heat dissipation of the heating circuit
relative to the outdoor temperature.
The demand for heat is different due to differences in the type of building/insulation/
type of heating/outdoor temperature. For this reason the controller can make use of a
normal straight curve (Setting simple) or a split curve (Setting split).
In the simple setting the curve can be adjusted with the help of the graphic diagram.
The slope is changed, and the calculated reference flow temperature is displayed
for -20 °C.
