F 5.4 - Day correction
menu 5.4
= parallel shift of the curve
The day correction means a parallel shift of the heating curve during the daytime operating hours, since
depending on the outdoor temperature it is possible that the building may not be optimally heated with the set
characteristic. If the characteristic is not optimized, the following situation may occur:
in hot weather - the rooms are too cold
in cold weather - the rooms are too hot
In this case, one should gradually reduce the characteristic slope in steps of 0.2, each time raising the day
correction by 2-4 °C.
This procedure can be repeated several times as needed.
Setting range: from -10 °C to +50 °C
Default: 5 °C
F 5.5 - Night correction
menu 5.5
= parallel shift of the curve
The night correction produces a parallel shift of the heating curve during the nighttime operating hours. If
a negative value is set for the night correction, the reference flow temperature is lowered accordingly during
the nighttime operating hours. In this manner, primarily at night, but also during the day when no-one is at
home, energy can be saved.
Example: A day correction of +5 °C and a night correction of -2 °C produces a reference flow
temperature in nighttime operation that is by 7 °C below that of daytime operation.
Setting range: from -30 °C to 30 °C
Default: -2 °C
F 5.6 - Comfort temperature boost
menu 5.6
= parallel shift of the curve
The comfort temperature boost is added to the set day correction. In this manner it is possible to carry out
quick heating and/or a higher temperature in the living spaces at a certain time each day.
Setting range: from 0 °C to 15 °C
Default: 0 °C = off.
F 5.8 - Reference / actual -
menu 5.8
= switch-on hysteresis for additional heating
This setting determines the allowed undershoot of the heating circuit temperature under the calculated
reference flow temperature. If the heating circuit flow temperature falls below the reference temperature by
this value, the additional heating (R5) is activated after a delay of 5 minutes.
Setting range: -10 °C to 10 °C
Default: -2 °C
The additional heating (relay R5) is started when the flow temperature (in case of 2 heat circuits:
one of the flow temperatures) is below the reference flow temperature for 5 minutes continuously.
F 5.9 - Reference /
menu 5.9
= vypínací hystereze
(only if sensor S4 is connected)
This settings determines the allowed overstepping of the heating circuit temperature to the calculated
reference flow temperature at sensor S4. If the temperature at S4 exceeds the reference flow temperature by
this value, the additional heating is switched off.
Setting range: 1 °C to 10 °C
Default: 2 °C
If sensor 4 is not connected, the additional heating at R5 is switched off when the sensor of
the heating circuit S2 (respectively, of the heating circuits S2 and S3) reaches or exceeds the
reference flow temperature.
It is recommended to install sensor 4 in the accumulation tank at the same level (or below) of the
heating circuit conduit to prevent unnecessary switching of the additional heating.
