Release Method
You may select 3 different types of releases for the buffer. Likewise, the release type only has an affect in
the furnace operating modes "Pellets automatic", and "Bulk materials-automatic".
Always Off
If you select always off, the buffer is not charged to its required temperature. The buffer is maintained
above 50 °F in the freeze protection mode (outside temperature is lower than auto freeze protection
temp. Refer to general heating cycle 1 settings).
Always On
The buffer temperature is recharged if the buffer temperature top has dropped below the set minimum
buffer temperature top.
With Clock
The buffer is only recharged within the set release periods, if its buffer temperature top has dropped
below the set minimum buffer temperature top.
Release Period 1 to 3
You can set 3 different release periods for the buffer from 0:00 to 24:00 hours. If you do not require all
release period, set the starting and ending value to the same setting value in order to deactivate this
release period.
