10 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.
CAUTION
10.1 Climate related curves
The Climate related curves can be selected in the user interface. Once the curve is selected, the target outlet temperature. In
each mode, user can select one curve from curves in the user interface(curve can’t be selected if dual room thermostat function
is enabled.
It’s possible to select curves even dual room thermostat function is enabled.
The relationship between outdoor temperature (T4/°C) and the target water temperature(T1S/°C) is described in the table and
picture in the next page. )
