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

200A Influence room temperature hook-up

Influence of the room temperature on the set flow tem-
perature of the heating circuit with weather-compensa-
ted control. For each Kelvin of differential between the
set room temperature and the actual temperature, the
set flow temperature is adjusted by the specified value.
Requirements:
Room temperature sensor installed ("Remote con-
■
trol 2003")
■ Room temperature hook-up active ("Room temper-
ature hook-up 200B")
200B Room temperature hook-up
In conjunction with room temperature sensor
("Remote control 2003").
Value Meaning
"0" Weather-compensated control without room
influence: Set flow temperature is not adjus-
ted.
"1" Weather-compensated control with room tem-
perature hook-up only for "Reduced" operat-
ing status
200E Max. flow temperature heating circuit
The set flow temperature, which results from the out-
side temperature, the heating curve and the set room
temperature of the selected heating circuit, is limited
by this parameter to a maximum value.
Note
■ Since the heat pump control unit only limits the set
value with this parameter, a temperature limiter for
restricting the maximum temperature (accessories)
must be installed in the flow of an underfloor heat-
ing circuit.
■ For central heating via a ventilation heating circuit,
this value should not be set above 57 °C for all heat-
ing circuits.
2015 Runtime mixer heating circ
Time required by the mixer to completely switch
between 2 operating states (angle range 90°).
This value is a property of the mixer motor: See mixer
motor specification.
The mixer will "oscillate" if the set time for the mixer
used is too short.

Example:
■ Set room temperature = 20 °C
■ Actual room temperature = 18.5 °C
■ Deviation between set and actual room temperatures
= 1.5 K
"Influence room temperature hook-up 200A" = 2

Adjustment of the set flow temperature

1.5 K 2 = 3 K

Note
Room temperature hook-up is OFF at a setting of "0".

Value Meaning
"2" Weather-compensated control with room tem-
perature hook-up only for "Standard" operat-
ing status
"3" Weather-compensated control with room tem-
perature hook-up for "Reduced" and "Stand-
ard" operating status

Note
This parameter only affects mixers that are switched
directly by the heat pump control unit (not for switching
via KM-BUS). This parameter is without effect for heat-
ing circuits without mixer.
