10.1 Climate related curves
It is important that all information in this chapter is read sequentially by the installer and that the system is configured as applicable.
The unit should be configured by the installer to match the installation environment (outdoor climate, installed options, etc.) and user expertise.
10 START-UP AND CONFIGURATION
The climate related curves can be selected in the user interface (refer to the operation manual,
6.2.2 Weather Temperature set,
if ECO mode
is enabled, please refer to the operation manual
6.2.3 ECO Mode
). Once the curve is selected, the target outlet water temperature is determined
by the outdoor temperature. In each mode, you can select one curve from eight curves in the user interface. And it designed for three applications.
Floor heating Low temperature / Floor heating High temperature and Radiator. For some new building with good insulation, you can adopt floor
heating Low temperature curves. And set corresponding curves in controller. If your building insulation is not so well, you can choose floor heating
high temperature curves. If you need relace a boiler for radiator, Please choose radiator curves.
The relationship between outdoor temperature(T4
/℃
) and target outlet water temperature(T1s
/℃
) is described in the table and picture below. The
selection of the low/high temperature curve can be done in the user interface. In cool mode refer to
10.7 Field setting/COOL control /How to set
the COOL mode
. In heat mode refer to
10.7 Field setting/HEAT control/How to set the HEAT mode
.
