The linear sensor curve is defined over two fixed points. The setting is
made with two parameter pairs for function value and frequency value. A
frequency value is used in place of the voltage values when setting the
Flow measurement Hz. The controller receives a signal for the measured
flow rate. The corresponding flow rate is calculated via the linear curve,
which is defined via two fixed points (input value 1/function value 1 and
input value 2/function value 2).
Function output P1 (6085)
A speed signal can be output at output P1 for the following pumps:
None | Boiler pump Q1 | DHW pump Q3 | DHW interm circ pump Q33 |
Heat circuit pump HC1 Q2 | Heat circuit pump HC2 Q6 | Heat circuit pump
HC3 Q20 | Collector pump Q5 | Solar pump ext exch K9 | Solar pump
buffer K8 | Solar pump swi pool K18
Signal logic output P1 (6086)
The PWM output P1 can be output inverted using signal logic output P1.
Sensor type collector (6097)
Selection of used sensor types for measurement of the collector
temperature.
Readjustm collector sensor (6098)
Setting a correction value for collector sensor 1.
Readjustm outside sensor (6100)
Setting a correction value for outside sensor.
Time constant building (6110)
The value set here influences the reaction speed of the flow setpoint in
case of fluctuating outside temperatures as a function of the building
design.
Example values (refer also to Quick setback):
40 for buildings with thick walls or outer insulation.
20 for buildings of normal building design.
10 for buildings of light building design.
Central setp compensation (6117)
The central setpoint lead monitors the heat generator setpoint to the
required central flow temperature. With the setting the maximum corrector
is restricted, even if a larger adaptation should be required.
Frost protection plant (6120)
The heating circuit pump is activated without heat request subject to
outside temperature. If the outside temperature reaches the lower limit
value of -4°C, the heating circuit pump is activated. The pump is activated
every 6 hours for 10 minutes when the outside temperature is between
-5°C and +1.5°C. When the upper limit value of 1.5°C is reached, the
pump switches off.
