Max. FT 45°C
(setting range 30...80°C)
The maximum flow temperature set here puts an upper limit on the heating circuit
characteristic to prevent the heating circuit from overheating. This is particularly
important in the case of underfloor heating, as the plastic piping or floor covering, can
be damaged if the flow temperature is too high. If the set value is exceeded, the mixing
valve closes and the circulation pump is turned off.
With underfloor heating an additional safety thermostat (not included) needs to be
connected in series with the circulation pump in addition to the electronic flow tempe-
rature limiter.
Heating curve 1.2 (setting range 0.0...2.1)
The heat output is controlled on the basis of outside temperature using the characteristic.
The following diagram shows the effect of the selected characteristic heating curve on
the target flow temperature of the heating circuit.
The right characteristic is determined by establishing the point of intersection of the
calculated maximum flow temperature (design temperature) and the minimum outside
temperature.
Example: At a design outside temperature of -12°C and a flow temperature of 60°C
does the intersection give a steepness of 1.2 as the setting.
Day corr. 5K (setting range 0...50K)
Day correction is used to carry out a parallel translation of the heating characteristic
during the day operating periods, as it is possible that, depending on the outside tem-
perature, the building is not being heated optimally with the set characteristic.
The following situations frequently occur if the characteristic has not been optimised:
In hot weather – living space too cold
In cold weather – living space too hot
If this happens, reduce the characteristic heating curve in steps of 0.2 points and in-
crease the day correction by 2-4°C in each case. This process can be repeated several
times if necessary.
Comfort boost off
(setting range off...10K)
In the day operating periods with activated comfort boost this value is added to the
characteristic on top of the day correction in order to achieve a higher temperature in
the living space.
Night reduc. -2K (setting range +10...-30K)
If a negative value is set for night reduction, the flow temperature of the set characteristic
will be reduced in the periods during which the system is not in day mode. This reduces
the room temperature and therefore saves energy mainly at night, but also during the
day when no one is at home.
Example: With day correction of +5K and night reduction of –2K the target flow tempe-
rature is reduced by 7°C in night mode.
“04 Mode” menu
In this menu the controller can be switched from automatic to continuous day, continu-
ous night, off, manual or target mode.
Auto = Automatic mode
The controller works normally with the described functions.
ConDay
= Continuous day mode
The controller operates continuously in day mode with the set day correction. The
preset operating periods are disregarded. If this mode is activated, “ConDay mode” will
appear on the display from time to time.
ConNight = Continuous night mode
The controller operates continuously in night mode with the set night reduction. The
preset operating periods are disregarded. If this mode is activated, “ConNight mode”
will appear on the display from time to time.
