6.5. - Heat quantity
menu 6.5
6.5.1 - Prodleva
menu 6.5.1
When the heat meter mode „Flow rate“ is selected, an approximate heat quantity is calculated using the va-
lues the user has to enter. These are type of glycol/AntiFreeze, glycol portion and
fl
ow rate. These values are
put into correlation with the temperature data of collector sensor and storage sensor. If necessary a correction
value for
Δ
T can be set: Since for the heat meter the collector and the storage temperature are used, a diffe-
rence to the
fl
ow respectively return
fl
ow temperature can be compensated by changing Offset
Δ
T accordingly.
Example:
Displayed collector temp. 40 °C, measured
fl
ow temperature 39 °C, displayed storage temperature 30 °C,
measured return temperature 31 °C = results in a correction value of -20% (displayed
Δ
T 10K, real
Δ
T 8K =
-20% correction).
Note:
The heat quantity measured in the mode “Flow rate” is a calculated approximation for function
control of the system
.
6.5.1.1. - Flow sensor (X)
menu 6.5.1.1
This determines the sensor that is used to measure the
fl
ow temperature (hot side)..
Settings range: S1-S8, VFS1-2, active collector, active storage/ Default setting: S1
6.5.1.2. - Return sensor
menu 6.5.1.2
This determines the sensor that is used to measure the return temperature.
Settings range: S1-S8, VFS1-2, active collector, active storage/ Default setting: S1
6.5.1.3. - Anti freeze type
menu 6.5.1.3
Set the type of antifreeze
fl
uid used. If none is used, please set to 0.
Settings range: Ethylene, Propylene / Default setting: Ethylene
6.5.1.4. - Glycole percentage
menu 6.5.1.4
The amount of antifreeze agent in the system.
Settings range: 0-100 % / Default setting: 45 %
6.5.1.5. - Flow rate (X)
menu 6.5.1.5
Flow rate that is used to calculate the heat quantity
This determines the
fl
ow rate in litres per minute that is used for the calcualtion of the heat quantity.
Settings range: 0-100 l/min / Default setting: 5 l/min
6.5.1.6. - Offset
Δ
T
menu 6.5.1.6
Correction value for temperature difference
Since for the heat meter the collector and the storage temperature are used, a difference to the
fl
ow respecti-
vely return
fl
ow temperature can be compensated by changing Offset
Δ
T accordingly.
Example:
Displayed collector temp. 40 °C, measured
fl
ow temperature 39 °C, displayed storage temperature
30 °C, measured return temperature 31 °C = results in a correction value of -20% (displayed
Δ
T 10K, real
Δ
T
8K = -20% correction).
Settings range: -50 to +50 % / Default setting: 0 %
