421 Temperature adjustment

The temperature adjustment (climatic ad-
justment where an outdoor sensor is fi tted)
of a building consists of maintaining the in-
door temperature at a constant level while
the climatic conditions change.
To achieve this result the Clima Manager
modulates the temperature of the hot wa-
ter fl ow to the heating bodies in accordance
with the indoor and/or outdoor temperature
recorded by the sensors.
The variation in fl ow temperature is illustrat-
ed by a pre-established curve which is then
compared with the outdoor temperature
values.
Temperature adjustment parameter values:
0 = fi xed point temperature
1 = on/off devices
2 = room sensor only
3 = outdoor sensor only
4 = room sensor + outdoor sensor
422 Temperature adjustment curve
The choice of curve depends on the type of
heating system used:
• low-temperature system
(fl oor panels)
curve between 0.2 and 0.8
• high-temperature system
(radiators)
curve between 1.0 and 3.5
60
The checking process for the suitability of
the curve requires a long period of time dur-
ing which several adjustments may be nec-
essary.
When the outdoor temperature falls (winter)
three conditions may arise:
1. The temperature of the room may fall,
indicating that a steeper curve should be
set.
2. The temperature of the room may rise,
indicating that a gentler curve should be
set.
3. The temperature of the room remains
constant, indicating that the set curve is
exactly right.
Once you have found the curve which main-
tains the room temperature at a constant
level, check the actual temperature value.
423 Parallel shifting of the curve
If the atmospheric temperature is higher
than the desired value the curve must be
shifted lower. If, on the other hand, the room
temperature is too low the curve should be
shifted upwards. If the temperature of the
room corresponds with the desired value,
the curve is in the right position.
In the graph below, the curves have been
divided into two groups:
• low-temperature systems
• high-temperature systems
The two groups are divided based on the
diff erent point of origin of the curves for
high-temperature systems, which is +10°C, a
correction which is usually made to the fl ow
temperature in this type of system, during
climatic adjustment.
