Components/Heating
E-heating/Hotgas reheat/Hot water reheat
Depending on which type of reheat you have configured, different parameters
are decisive.
The start temperature for every heating is entered as a negative difference to
the room temperature setpoint.
➊ The hysteresis for the heating stop is only
valid for heatings with on/off-control.
➋
For proportional e-heatings/hot water reheats you can adjust a gradient, which
determines the temperature range in which the heating capacity increases
from 0 to 100%.
➌
Alarm parameter:

➍
Only the first heating can be proportional. If this is the case and if there are
several heatings (up to 3), only the start value and the gradient of the first hea-
ting are decisive for the control. Each time the proportional heating reaches
100% heating capacity another reheat is added and the first heating is reset to
0%. This way up to three individual heatings act as one proportional heating.
