Enable Flow Temperature Sensor Cooling Circuit - Viessmann VITOTRONIC 200 Service Instructions Manual

Parameter group Cooling
7107 Hysteresis room temp cooling circuit
Room temperature exceeds set room temperature
■
by the set value:
Cooling starts.
■ Room temperature falls below set room tempera-
ture by "Hysteresis room temp cooling circuit
7107" times 2:
Cooling is switched off.
Requirement: Room temperature sensor is connected
and enabled.
■ Heating/cooling circuit:
Remote control room temperature sensor ("Remote
control 2003")
Separate cooling circuit:
■
Room temperature sensor (connection to F16 on
controller and sensor PCB): See "Ranking room
temp sensor separate cooling circuit 7106".

7109 Enable flow temperature sensor cooling circuit

Flow temperature sensor cooling for cooling via heat-
ing circuit without mixer A1/HC1 or via a separate
cooling circuit: Connection at F14 on the controller and
sensor PCB
Note
For cooling via a heating circuit with mixer, the flow
temperature sensor used for central heating will also
be used for cooling.
7110 Cooling curve level
"Vitotronic 200" operating instructions
The flow temperature value determined from the cool-
ing curve is adopted directly as the set value for the
cooling circuit.
7111 Cooling curve slope
"Vitotronic 200" operating instructions
The flow temperature value determined from the cool-
ing curve is adopted directly as the set value for the
cooling circuit.

Value Meaning
"0" Flow temperature sensor for cooling is not in-
stalled. Flow temperature sensor secondary
circuit is used.
"1" Flow temperature sensor cooling is connec-
ted and will be used.
