3692 S With DHW charging
- DHW Instantly : When DHW request, the HP and the boiler are put into operation. The HP will stop when the primary
return temperature is over 55 °C.
- DHW Substitute : If the outdoor temperature is above 2 °C, the operation of the HP when DHW request last 5 minutes
at least. The HP operating time can be extended depending on the outdoor temperature. The boiler will activate then.

Installation configuration
5700 I Pre-setting
This control enables you to choose one of the 4 pre-selected installation configurations. The hydraulic layouts for the
various configurations are detailed in the section: "Installation Configurations".
- Pre-setting 1: 1 heating circuit with or without electrical back-up, with DHW tank.
- Pre-setting 2: 2 heating circuits with or without electrical back-up, with DHW tank.
- Pre-setting 3: Boiler connection and 1 heating circuit and DHW tank.
- Pre-setting 4: Boiler connection and 2 heating circuits and DHW tank.
- Pre-setting 5 and more: Not used.
