4. Select parameter.
2000 Standard room temperature
Set room temperature for weather-compensated or
room temperature-dependent heating or cooling mode
(standard room temperature).
Operating instructions
2001 Reduced room temperature
Set room temperature for reduced heating or cooling
mode (reduced room temperature).
"Vitotronic 200" operating instructions
2003 Remote control
One Vitotrol 200-A remote control (with room tempera-
ture sensor) can be used for each heating/cooling cir-
cuit.
Remote control installation and service instruc-
tions
Note
"Room temperature hook-up 200B" must not be set
to "0" if the room temperature sensor of the remote
control is to be used for room temperature hook-up for
a heating/cooling circuit.

Parameter group Heating circuits/Cooling circuits
Note
The parameters in parameter groups "Heating circuit
1", "Heating circuit 2" and "Heating circuit 3" are
identical.
The assignment to the heating circuit is determined by
the first digit of the parameter code:
2xxx For heating circuit 1 (without mixer A1/HC1)
3xxx For heating circuit 2 (with mixer M2/HC2)
4xxx For heating circuit 3 (with mixer M3/HC3)
The relevant parameters can only be set if a heating
circuit is included in the system scheme.
≙
Setting 1 0.1 °C
Note
The maximum value for "Reduced room temperature
2001" is 1 K below the current value for "Standard
room temperature 2000".
≙
Setting 1 0.1 °C
Value Meaning
"0" Remote control is not activated.
"1" Remote control for the selected heating/cool-
ing circuit is installed and activated. The room
temperature sensor is activated.
"2" External hook-up is active for the selected
■
heating/cooling circuit.
A demand for central heating/cooling is is-
■
sued via the 230 V~ digital inputs: See
"Main PCB".
Operation via remote control is not possi-
■
ble.
