6.6 Setting the DHW temperature
The Logamatic 2107 controls allows you to heat the DHW in an energy-
conscious manner. For this purpose, the DHW heating is equipped with a timer.
You can switch on the DHW heating by setting the desired temperature for the
domestic hot water. To save energy, DHW heating is switched off in night mode.
The DHW heating is set at the factory to "DHW AUTO" (automatic mode).
In this setting, the DHW heating starts 30 minutes before one of the two heating
zone switches to normal heating mode (day mode) and ends as soon as both
heating zones are in setback heating mode (night mode) with timer.
The DHW heating is set at the factory to 140°F (60°C) for automatic mode.
