6.3.1 System data
Settings for the entire system can be made in this menu. For example .
the value for the minimum outside temperature or the thermal storage
capacity of the building can be set here. Additional settings for heating!
cooling circuit 1 are available in this menu (if directly connected to the
heat source).

I The internal pump of the heat source is also used as the pump in heating/cooling circuit 1. A buffer cylinder I
is not required.
Heating/cooling circuit 1 is not directly connected to the heat source . In this case . a buffer cylinder is not
installed (see previous menu item). Pump PCl in heating/cooling circuit 1 is electrically connected to the
heat source . There is a bypass between heating/cooling circuit 1 and the heat pump for the purposes of
hydraulic separation.
1- With weather-compensated control the minimum outside temperature affects the heating curve
(7 Minimum outside temperature . page 17 and Menu for setting of the heating curve . page 20) .
The set building type affects the measurement of the outside temperature . The outside temperature is
delayed (dampened).
The measured outside temperature is included unadjusted in the weather-compensated control.
Measure of the thermal storage capacity of the heated building (7 Type of building . page 17).
High storage capacity . significant damping of the outside temperature. e.g. brick building
Medium storage capacity . ~edium damping of the outside temperature. e.g. hollow concrete blocks
Low storage capacity. low damping of the outside temperature. e.g. prefabricated building. wood-frame -'
construction
Frost sensor for cooling installed .
No frost sensor for cooling installed.
The minimum outside temperature is the average value of each of the
coldest outside temperatures or recent years. and it has an influence on
the heating curve . The value for the region can be taken from the
required heat load calculation that should be done for every building or
from the climate zone chart or from Tab . 25 .

Table 25 Minimum outside temperatures for Europe
Type of building
If damping is activated. the adjustment of the outside temperature
fluctuations can be set with the building type. By adjusting the outside
temperature thermal inertia of the building mass is taken i nto account.
Thus. by setting the building type the control can be adapted to suit the
characteristics of the building.

This greatly simplified example shows how the adjusted outside
temperature follows the current outside temperature. but does not
reach its extreme values.
