8.4.5 Holiday programs

The heating circuits may be set to a selectable operation level with the holiday
program during a certain holiday period.
8 vacation periods can be selected with this preselection.
Entering the holiday start
Input of holiday end
Selection of the operation level (reduced setpoint or frost protection) for the holi-
day program.
Note: A holiday period ends each time on the last day at 12:00 AM (00:00). The
holiday programs are only activated in the operation mode Automatic .

8.4.6 Heating circuits

Setting the maximum comfort setpoint in the heating phases. Without room sen-
sor or with the room influence (prog.no. 750, 1050, 1350), this value is used for
calculation of the flow temperature, to theoretically reach the set room tempera-
ture.
Setting of the desired room temperature during the reduced heating phase. With-
out room sensor or with the room influence (prog.no. 750, 1050, 1350), this value
is used for calculation of the flow temperature, to theoretically reach the set
room temperature.
Setting of the desired room temperature during the frost protection operation.
Without room sensor or with the room influence (prog.no. 750, 1050, 1350), this
value is used for calculation of the flow temperature, to theoretically reach the
set room temperature. The heating circuit remains turned off until the flow tem-
perature drops so far that the room temperature falls below the frost protection
temperature.
Using the heating curve, the flow temperature setpoint is formed, which is used
for control of the heating circuit, based on the outside temperature. The slope of
the curve indicates by how much the flow temperature changes with changing
outside temperature.
