Operation
Overview of display values and settings
T-LIMIT DAY/T-LIMIT N (Day/Night)
Only valid if the function is activated
=> Set value "Expert/Heating circuit/
PUMP MODE= 01=> Pump switching
according to heating limit"
If the outside temperature that is
measured and calculated by the
controller exceeds the heating limit
specified here, 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 by 1K
(= 1°C).
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 "Circulation
pump control")
HEAT SLOPE
The gradient of the heat slope indicates
by how many degrees the flow
temperature changes if the outside
temperature 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

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.
