Cooling Circuit; Room Temperature Separate Cooling Circuit; Minimum Flow Temperature For Separate Cooling Circuit - Viessmann VITOCAL 300-G Installation And Service Instructions Manual

Parameter group cooling

7101 Cooling circuit

"Cooling circuit 7101"
This parameter specifies whether cool-
ing occurs in one of the heating circuits
or in a separate cooling circuit.
Valu Explanation
e
"1" Cooling on heating circuit A1
"2" Cooling on heating circuit M2
"3" Cooling on heating circuit M3
"4" Cooling a separate cooling cir-
cuit

7102 Room temperature separate cooling circuit

"Room temperature 7102"
With this parameter a different set room
temperature than for the heating circuits
can be specified for the separate cooling
circuit. This makes it possible, for exam-
ple, to also cool a storage room in winter,
independent of the set room tempera-
ture.

7103 Minimum flow temperature for separate cooling circuit

"Minimum flow temperature 7103"
If a lower set flow temperature than the
value specified here results due to out-
side and room temperatures according
to the cooling curve, the flow tempera-
ture is regulated to this value.
212
Note
Cooling mode is not possible for several
heating or cooling circuits simultane-
ously.

Note
Only the set flow temperature is limited
with this value, not the actual tempera-
ture.
The minimum permissible set flow tem-
perature specified here applies both for
cooling a heating circuit as well as for
cooling a separate cooling circuit.
