Yes: The heating circuit can be supplied from the buffer storage tank.
With prim contr/system 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 segment in which this controller is located (LPB bus system)
and which is controlled with a primary control.
No: The heating circuit is supplied without primary controller/system
pump.
Yes: The heating circuit is supplied from the primary controller by the
system pump.
Pump speed reduction (880, 1180, 1480)
Speed regulation of the heating circuit pump can be done according to
operating level
or
pump curve
.
Operating level
: With this option the speed of the heating circuit pump is
actuated according to the operating level. The pump is controlled in
operating level
Comfort
(incl. optimization) or during active floor curing
function at maximum speed. With reduced operating level the pump is
controlled with the parameterized minimum speed.
Characteristic
: With the weather-compensated control variant (with or
without ambient temperature compensation), the speed of the heating
circuit pump will be kept at the minimum speed for as long as it remains
possible to meet the heat demand. In order to enable the heat demand
to be met at reduced speed, the heating curve is increased. This flow
increase is parametrisable. This setting defines the flow increase in
percent at minimum heating circuit pump speed. The speed is only
increased when the maximum permitted flow setpoint is reached.
Temp differential nominal: The spread between boiler flow temperature
and boiler return temperature is called the temperature rise.
Important
Since regulation is via the boiler sensor, this setting is only
suitable if one pump heating circuit is available.
Pump speed min (882, 1182, 1482)
The minimum speed for the heating circuit pump can be specified using
this function.
Pump speed max (883, 1183, 1483)
The maximum speed for the heating circuit pump can be specified using
this function.
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 using 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
included in the temperature request or not.
No: The temperature request remains unchanged. The calculated
correction value is not added.
Yes: The temperature request includes the flow setpoint correction.
Operating level changeover (898, 1198, 1498)
When an external timer is used above the inputs
Hx
selection of the
operating level to which the heating circuits are to be switched is possible.
