If the system layout is modified later, all settings are lost. For this
reason a warning question is always displayed when settings
are changed in the Arr parameter.
Confirm the warning question only if you really want to change
the system layout!
Maximum storage cylinder temperature
Maximum desired storage cylinder temperature.
Setting range: 4 - 95 °C (4 - 90°C for Arr 3).
Default settings: 60 °C.
9
The controller has a fixed safety deactivation function that
deactivates the system as soon as the storage cylinder
reaches a temperature of 95 °C.
Pump control
Set the type of pump control required.
Setting range: OnOF, PULS, PSOL, PRIS.
Default settings: PSOL.
The following control types can be selected:
Control for standard pumps without speed control
− OnOF (pump activated / deactivated)
Control for standard pumps with speed control
− PULS (pulsed control via semiconductor relay)
High efficiency (HE) pump control
− PSOL (PWM curve for an HE solar pump)
− PRIS (PWM curve for an HE heating pump)
To reduce the frequency of high efficiency pump starts, the
controller automatically extends its functioning when no speed
control signal is transmitted by the relay (PUM = PSOL or PRIS).
This relay remains activated for an hour after deactivation con-
ditions are satisfied.
Minimum speed
Set minimum speed for the corresponding pump.
Setting range: (10) 30 - 100 %.
Increment: 5%.
Default settings: 30%.
9
If users with no speed control (e.g. valves) are connected,
minimum relay speed must be set at 100%.
Maximum speed
Set maximum speed for the corresponding pump.
Setting range: (10) 30 - 100 %.
Increment: 5%.
Default settings: 100 %.
9
If electrical equipment with no speed control (e.g. valves) is
used, set the relay speed to 100 % or set the pump control
to OnOF to deactivate speed control.
Confirm
After the last parameter of the startup menu, you are asked to
confirm the settings made in it.
Press button 3 to confirm the settings made in the startup menu.
9
Settings made in the startup menu can be modified in the
corresponding control parameter at any time, even after
startup.
