Start-Up And Configuration; Climate Related Curves - HTW A60CGN8PLUS Manuel De L'utilisateur

1. when EVU signal is on, the unit operate as below:
DHW mode turn on, the setting temperature will be changed to 70℃
automatically, and the TBH operate as below:T5<69. the TBH is on,
T5 ≥ 70, the TBH is off. The unit operate in cooling/heating mode
as the normal logic.

9 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.

9.1 Climate related curves

The climate related curves can be selected in the user interface. Once the curve is selected, the target water flow temperature
in each mode is calculated by the curve.
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 tables and
pictures. )

The automatic setting curve
The automatic setting curve is the ninth curve,the ninth curve can be set as following:
T1SETH1
T1SETH2
State:In the setting the wired controller, if T4H2<T4H1, then exchange their value; if T1SETH1<T1SETH2, then
exchange their value.

2. When EVU signal is off, and SG signal is on, the unit operate
normally.
3. When EVU signal is off, SG signal is off, the DHW mode is off, and
the TBH is invalid, disinfect function is invalid. The max running time for
cooling/heating is "SG RUNNIN TIME", then unit will be off.
