You can now enter up to three release periods for the weekdays Monday to Friday. If furnace operating
mode “Bulk materials auto control” is set, the furnace will only start on weekdays if a heating circuit
demand is present and a time release is given.
Once you have entered the desired release periods, briefly press the ESC button to quit the menu. The
selection menu “BM AUTO CONTROL – Mo-Fr/ Sa-Su” is shown on the display. The release periods for
Saturday and Sunday are set in the same manner.
Release Mode “Monday -Sunday”
Select release mode “Monday – Sunday” if you want to enter identical release periods for every day.
The screen “BM AUTO CONTROL – Mo-Su” is shown on the display:
You can now select up to three release periods. If furnace operating mode “Bulk materials auto control”
is selected and there is a call for heat, the furnace will start as soon as a time window
becomes active.
Release Mode “manual start”
If release mode “manual start” is selected, the ignition process is started immediately if the furnace
operating mode is set to “Bulk materials auto control“. This release mode does not require the presence
of a heating circuit demand. One should therefore ensure that there is sufficient demand. The only
condition for ignition is that the current furnace temperature is lower than the set “boiler target
temperature” less the set “starting difference”.
