Temp. Limit Op. Status Fixed Value For Buffer Cylinder - Viessmann VITOTRONIC 200 Service Instructions Manual

7208 Temp. limit op. status fixed value for buffer cylinder !

If the long term average outside temper-
ature exceeds this temperature limit, the
heat pump control unit blocks the oper-
ating status "Fixd value" (e.g. in sum-
mer). The heating water buffer cylinder
will then only be heated to the set tem-
perature for operating status "Stand-
ard".
Operation of the heating water buffer cyl-
inder in operating status "Fixd value"
automatically continues if the long term
average outside temperature falls below
this temperature limit by 0.5 K (hystere-
sis).
Note
This function is only available for system
schemes 1 and 2 if value "1" is set
under "Buffer cylinder 7200".
