User Area Part 2: Overview of display values and settings
26
T-LIMIT DAY/T-LIMIT N (Day/Night)
Only valid if the function is activated => Set value
"Expert/Heating circuit/PUMP MODE= 01=> Pump switch-
ing according to heating limit"
If the outside temperature that is measured and calculated
by the controller exceeds the heating limit specified here
by 1 K (= 1 °C), heating is disabled, the pumps switch off
and the mixers are closed. The heating is enabled again
when the outside temperature drops below the set heating
limit.
T-LIMIT DAY => applies during heating times
T-LIMIT N => applies during reduction times
"----" => The heating limit is deactivated. The circulation
pump is switched in accordance with the standard function
(see chapter entitled "Circulation pump control")
HEATSLOPE
The gradient of the heat slope indicates by how many de-
grees the flow temperature changes if the outside tem-
perature rises or drops by 1 K.
Setting tip:
At cold outside temperatures, room temperature too low =>
Increase heat slope (and vice-versa)
At high outside temperature (e.g.16 °C) room temperature
too low => correction via set room temperature
Flow temperature [°C]
Outside temperature [°C]
Heat slope diagram (setting aid)
Setting 0 => Room control only
! The heat slope can best be set at outside
temperatures below 5 °C. The change in heat slope
setting must be made in small steps and at long
intervals (min. 5 to 6 hours) because the system
must first adjust to the new values each time the
heat slope is changed.
