Excess heat draw
(861, 1161, 1461)
If the excess temperature draw is activated via input H1 to H5 or a maximum
temperature is exceeded in the system, this excess heat energy can be released
by a heat draw of the room heating.
-
Off
: the function is switched off.
-
Heating mode
: the function is limited to only a draw during the heating time.
-
Always
: the function is generally released.
With buffer storage tank
(870, 1170, 1470)
This parameter establishes whether the heating circuit can be supplied by a buf-
fer or only from a heat generator. The function has the effect of whether with a
heat demand the system pump goes into operation.
-
No
: the heating circuit is supplied from the boiler.
-
Yes
: the heating circuit can be supplied from the buffer.
With primary controller/sys-
tem pump
(872, 1172, 1472, 5092)
This parameter establishes whether a zone system pump goes into operation
with a heat demand of the heating circuit. This system pump is based on the seg-
ment, in which this controller is located (LPB bus system) and which is controlled
with a primary control.
-
No
: the heating circuit will be fed without primary control unit/feed pump.
-
Yes
: the heating circuit is supplied after the primary control with the system
pump.
Pump speed reduction
(880, 1180, 1480)
Speed reduction of the heating circuit pump can be done acc. to operating level or
acc. to pump characteristic curve.
Operating level
: With this option the speed of the heating circuit pump is calcula-
ted acc. to the operating level. The pump is controlled in operating level comfort
(incl. optimization) or during active floor curing function with parameterized ma-
ximum speed. With reduced operating level the pump is controlled with the para-
meterized minimum speed.
Characteristic
: The pump speed of the heating circuit pump is calculated based on
the actually held flow temperature and the current flow set point. The common
flow temp setpoint is used for the actual value If no common flow temperature
sensor is available the boiler flow actual value is used. The temperature actual va-
lue is attenuated with a filter (time constant capable of parameterization)
Pump speed min
(882, 1182, 1482)
Using this function the minimum speed for the heating circuit pump can be spe-
cified.
Pump speed max
(883, 1183, 1483)
Using this function the maximum speed for the heating circuit pump can be spe-
cified.
Curve readj at 50% speed
(888, 1188, 1488)
Correction of the flow setpoint with reduction of the pump speed by 50%. The
correction is calculated from the difference from the flow setpoint according to
the heating curve and current room setpoint.
Flow setp readj speed ctrl
(890, 1190, 1490)
Here it can be specified whether the calculated flow setpoint correction is inclu-
ded in the temperature request or not.
-
No
: the temperature request remains unchanged. The calculated correction va-
lue was is not added.
-
Yes
: the temperature request includes the flow setpoint correction.
