Settings cooling
Settings cooling
This setting is used to determine the allowed overshoot of the
fl
ow temperature at sen-
sor S2 over the calculated reference
fl
ow temperature. If the measured temperature
at S2 exceeds the reference temperature for the time period set inf 5.2.8, cooling is
switched off.
Settings range: -10°C to 10°C / Default: 3°C
5.2.3. - On hysteresis
Slope of the charakteristik curve: Reference fl ow temperature
Changes the relation of room temperature and reference
fl
ow temperature for the
cooling mode. The higher this value, the colder the reference
fl
ow temperature.
Settings range: 1.0 to 10.0 / Default: 2.0
5.2.4. - Slope reference fl ow
Room reference temperature in cooling mode
This temperature is the target temperature for the controlled room. The
fl
ow tempera-
ture is regulated accordingly.
Settings range: 15 to 30 / Default: 25
5.2.5. - Room reference cooling
Minimum
fl
ow temperature in cooling mode
This is the lower limit of the
fl
ow reference temperature for cooling.
Einstellbereich: 5 °C bis 20 °C / Voreinstellung: 10 °C
5.2.6. - Min. fl ow cool
Maximum
fl
ow temperature in cooling mode.
This is the upper limit of the
fl
ow reference temperature for cooling.
Einstellbereich: 20 °C bis 40 °C / Voreinstellung: 25 °C
5.2.7. - Max. fl ow cool
Delay of cooling and additional heating
To prevent switching of additional heating or cooling when temperature
fl
uctuations oc-
cur, it is possible to delay the switching of the corresponding relay for up to 5 minutes.
When the conditions are still met for the whole time, the relay is switched.
Settings range: 0 to 5 minutes / Default: 1 minute
5.2.8. - Delay
Delay applies to heating and cooling (see also „5.1.9. - Delay“ on page 23)
Caution
Yes:
Cool down to Reference
fl
ow tempe off hysteresis („5.2.2. - Off hyster-
esis“ on page 24) measuring at
fl
ow sensor S2 and buffer S3.
No:
Cool down to Reference
fl
ow tempe off hysteresis („5.2.2. - Off hysteresis“
on page 24) measuring at
fl
ow sensor S2, temperature at buffer S3 is ignored.
Settings range: Yes, No / Default: Yes
