External Wiring of Operation/ Fault
● The terminal will be conducted when the unit is running,
and will be disconnected when the unit is turned off or stood by.
● The terminal 25 \26 and 31\30 will be conducted when there is a
running fault, and be disconnected when the unit is running correctly.
● The connection is described.

6 START-UP AND CONFIGURATION

The unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user expertise.
It is important that all information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.
6.1 Climate related curves
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
in the next page.
