Room Temperature Control - Viessmann VITOTRONIC 200 Service Instructions Manual

Parameter group Heating circuits/Cooling circuits
2003 Remote control
Note
In the heat pump setting "Manual mode" the remote
controls have no function: See "Vitotronic 200" operat-
ing instructions.

2005 Room temperature control

Room temperature-dependent control of the heating/
cooling circuit
Value Meaning
"0" Weather-compensated control for central
heating is enabled:
The heat pump control unit calculates the set
flow temperature for the heating circuit from
the set room temperature, the outside tem-
perature and the set heating curve.
"1" Room temperature-dependent control for cen-
tral heating is enabled:
"Heating curve level 2006" and "Heating
■
curve slope 2007" are not adjustable.
Room temperature sensor is connected and
■
enabled ("Remote control 2003" set to
"1"), otherwise automatically stays set to
"0".
The heat pump control unit calculates the
■
set flow temperature from the current differ-
ential between the set and actual room tem-
perature.
System without buffer cylinder or with heat-
■
ing water buffer cylinder:
Room temperature-dependent cooling for
the heating/cooling circuit can be set with
"Room temperature control cooling cir-
cuit 7105".
System with heating water/coolant buffer
■
cylinder :
Weather-compensated control for central
cooling is enabled.
2006 Heating curve level
Operating instructions
The values determined from the heating curves for the
flow temperature are adopted directly as set values for
the heating circuits.
2007 Heating curve slope

Value Meaning
"2" Room temperature-dependent control for cen-
tral cooling, weather-compensated control for
central heating
Only for system with heating water/coolant
■
buffer cylinder
"Cooling curve level 2040" and "Cooling
■
curve slope 2041" are not adjustable.
Room temperature sensor is connected and
■
enabled ("Remote control 2003" set to
"1"), otherwise automatically stays set to
"0".
The heat pump control unit calculates the
■
set flow temperature from the current differ-
ential between the set and actual room tem-
perature.
"3" Room temperature-dependent control for cen-
tral heating and for central cooling
Note
If the heating circuit is used for supply air heating (ven-
tilation heating circuit), room temperature-dependent
control can not be set ("Enable reheater bank
hydraulic 7D02").
