5.4 Boiler modes
5.4.1 "Automatic” mode without storage tank
When “
Automatic
” is selected without a storage tank, the boiler only produces heat during the specified boiler
times. Outside these times the boiler follows the shutdown procedure and switches to "
Standby
" status. It is,
therefore, important to note that in this mode the heating circuits and DHW tank are only supplied with heat
during the boiler times.
In Example 1 the boiler times have been set to cover the necessary heat requirement. The heating times and
DHW tank loading times have been set within the boiler time range, with the heating time being extended
approximately one hour beyond the boiler time. This allows the residual energy in the boiler to be used by the
heating circuits after the end of the boiler time.
Note that outside the boiler times for setback mode, heat is only available until the boiler temperature falls below
the setting value (parameter "
Minimum boiler temperature to release all pumps
").
Example 1: "Automatic” mode without storage tank
Boiler time 1
Boiler time 2
Heating time 2
Heating time 1
setback mode
DHW tank loading time 1
DHW tank loading time 2
Tip: In systems with solar panels, choose the DHW tank loading time so that solar energy can be used.
