curves

Contact type H1 (5951) Contact type H4 (5971) and Contact
type H5 (5978)
With this function, the contacts can be set as resting contact (contact
closed, must be opened for activating the function) or as working contact
(contact opened, must be closed for activating the function).
Voltage value 1 H1 (5953),Voltage value 2 H1 (5955), Function
value 1 H1 (5954) andFunction value 2 H1 (5956)
The linear sensor curve is defined over two fixed points. The setting is
made with two parameter pairs for Function value and Voltage value (F1 /
U1 and F2 / U2).
The function value is specified to a factor of 10, i.e. if you require 100°C,
you should select "1000".
Frequency value 1 H4 (5973), Function value 1 H4 (5974),
Frequency value 2 H4 (5975) and (5976)Function value 2 H4
F Frequency
W Water flow
The linear sensor curve is defined over two fixed points. The setting is
done with two parameter pairs for function value and frequency value (F1 /
U1 and F2 / U2).
RA-0000083
Function output P1 (6085)
This parameter is used to specify the function for the modulating pumps.
None: No output P1 exists.
Boiler pump Q1: The connected pump is used for recirculation of the
boiler water.
Hot water pump Q3: Actuator for DHW storage tank.
HW interm circ pump Q33: Charging pump for DHW cylinder with exter­
nal heat exchanger.
heating pump CH1 Q2: The pumped heating circuit HC1 is activated.
heating pump CH2 Q6: The pumped heating circuit HC2 is activated.
heating pump CH3 Q20: The pumped heating circuit HC3 is activated.
Collector pump Q5: A circulation pump for the collector circuit is required
for connection of a solar collector.
Solar pump ext exch K9: If several exchangers are connected, the buffer
storage must be set at the respective relay output. In addition, the type
of the solar regulating unit must be defined in prog.no. 5840.
Solar pump swi pool K18: If several exchangers are connected, the the
swimming pool must be set at the respective relay output. In addition,
the type of the solar regulating unit must be defined in prog.no. 5840.
Sensor type collector (6097)
Selection of used sensor types for measurement of the collector tempera­
ture.
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 de­
sign.
