volumetric flow can only be estimated
approximately.
Tip for calculating the flow:
approx. 0.8 [l/min] per square metre of collec-
tor surface area.

Warning! This value is not applicable to
Low Flow systems.
70 Value per impulse [millimetres/impulse]
[litres/impulse]
(With flow meter only)
The value per impulse of the flow meter
(optional) can be found in the flow meter
documentation.
71 Unit of the value per impulse set
(With flow meter only)
Switching between [ml/impulse] and [l/
impulse].
72 Distribution of flow for systems with 2
collectors
(System 4 only):
Enter the proportion of flow through both col-
lectors if both fill pumps are operating.
75 Fixed flow x for collector 1 [litres/min]
(Without flow meter only - see estimated pro-
duction)
76 Fixed flow x for collector 2 [litres/min]
(Without flow meter only - see estimated pro-
duction)
78 Mixture proportion
Systems 2, 9 -> No function:
The proportion of the mixture of heat exchange
fluid (fluid used to fill the solar heating installa-
tion) can be found in the documents provided
or alternatively requested from the installer.
79 Type of glycol
Systems 2, 9 -> No function:
(Solar heating installation documents/installer)
0 = Propylene glycol.
1 = Ethylene glycol.
84 T-Max storage cylinder outlet
84 = 50 – 75 °C: Maximum storage cylinder
temperature measured by sensor F4. The
pumps are switched off for as long as F4 >
P84.
85 T-Max storage cylinder inlet
85 = 60 – 110 °C: Maximum storage cylinder
temperature measured by sensor F3 when the
pump is running. The pump is switched off for
as long as F3 > P85.
86 T-Max storage cylinder outlet
86 = 60 – 110 °C: Maximum storage cylinder
temperature measured by sensor F4 when the
pump is running. The pump is switched off for
as long as F4 > P86.
87 Filling time
87 = 1 – 10 min

(display only).
PWM/0…10V pump control
These relay outputs are ideal for use with a
high efficiency pump. Pump speed can be
controlled by PWM or a 0-10 Volt input signal.
The control method (PWM or 0-10 Volt) can be
selected and the pump control values set in
the following parameters.
P101 Speed control
P101 = PWM; 0…10V
Selection of pump control mode.
P102 PWM base frequency
Only available if P101 = PWM
P102 = 180 Hz; 2 kHz: The desired speed (0
to 100 %) is achieved by the corresponding
PWM width ratio.
P103 PWM pump ON
Only available if P101 = PWM
P103 = 0 – 100 %: The PWM signal is sent for
5 seconds at the start of the pump run time to
ensure correct starting.
P104 PWM pump OFF
Only available if P101 = PWM
P104 = 0 – 100 %: 0% speed signal (the
pump is effectively switched off); can be iden-
tical to P105. The relay is deactivated.
P105 PWM min pump speed
Only available if P101 = PWM
P105 = 0 – 100 %: The minimum pump speed
signal while the pump is running.
P106 PWM max pump
Only available if P101 = PWM
P106 = 0 – 100 %: The maximum pump speed
signal while the pump is running.
P107 PWM PWM pump overspeed
Only available if P101 = PWM
P107 = OFF
P107 = 0 – 100 %:
Systems 1 to 12: Function not used
System 13: In the case of pumps with a kick-
down function, the maximum speed signal is
sent for the duration of filling time.
