Influence Room Temperature Hook-Up Cooling Circuit - Viessmann VITOTRONIC 200 Service Instructions Manual

7104 Influence room temperature hook-up cooling circuit

The higher the value, the greater the influence of the
room temperature on the set flow temperature of the
cooling circuit with weather-compensated control.
Condition:
Room temperature sensor is connected (e.g. via
Vitotrol).
Example:
See "Influence room temperature hook-up 200A".
7105 Room temperature control cooling circuit
For central cooling via a heating/cooling circuit or the
separate cooling circuit.
Value Meaning
"0" Weather-compensated control for central
cooling enabled:
The control unit calculates the set flow tem-
perature for the separate cooling circuit from
the set room temperature, the outside tem-
perature and the set cooling curve.
"1" Room temperature-dependent control for cen-
tral cooling enabled:
The control unit calculates the set flow tem-
perature from the current differential between
the set and actual room temperature. Slope
and level of the cooling curve for the separate
cooling circuit cannot be adjusted.
7106 Ranking room temp sensor separate cooling circuit
This parameter determines which room temperature
sensor is used for room temperature-dependent con-
trol of the separate cooling circuit.
The room temperature sensors of heating/cooling cir-
cuits A1/HC1, M2/HC2 and M3/HC3 are integrated into
the remote control.
Value Meaning
"0" Room temperature sensor connected directly
to the heat pump control unit (connection F16
on controller and sensor PCB)
"1" Room temperature sensor A1/HC1 is used:
Set "Remote control 2003" to "1".
7107 Hysteresis room temp cooling circuit
Hysteresis room temperature for room temperature-
dependent cooling mode via heating circuit or separate
cooling circuit.
!
Note
Room temperature hook-up is OFF at a setting of "0".
Set value without unit
!
Requirements:
■ Central cooling via separate cooling circuit: Room
temperature sensor connected to F16 on the control-
ler and sensor PCB.
Note
Alternatively, the room temperature sensor (installed
in the Vitotrol) of a different heating/cooling circuit
can also be used ("Ranking room temp sensor
separate cooling circuit 7106"
Central cooling via heating/cooling circuit: Remote
■
control is connected.
Note
Room temperature-dependent cooling ("Room tem-
perature control, cooling circuit 7105" set to "1")
and weather-compensated central heating ("Room
temperature control 2005" set to "0") can be set
simultaneously for one heating/cooling circuit.
!
Value Meaning
"2" Room temperature sensor M2/HC2 is used:
Set "Remote control 3003" to "1".
"3" Room temperature sensor M3/HC3 is used:
Set "Remote control 4003" to "1".
"4" Never adjust
