H0 Maximum electric pump head.
Fc Inverter carrier frequency
Dry running power. If you want to enable protection against
DR dry running, set the value of the absorbed power at Fn (normal
frequency) in dry running conditions, increased by 20%.
Time that passes between switching off one pump and
ET
switching on the other in twin systems.
Characteristic constant of the NTC resistance, used for the
B
measurement of fluid temperatures T and T1
Running time of the hydraulic circuit, it acts in an inversely
Td proportional way on the regulating speed in the T and DT
regulations.
Bs Parameter for setting up Booster mode
Ad Modbus address of the device
Br Serial communication baud rate
Pa Type of parity control
Sb Number of stop bits
Rd Minimum response time

Home Page
The main settings of the system are graphically summed up on the Home Page.
The icon at top left indicates the type of regulation selected.
The icon at centre top indicates the operating mode selected (auto or economy).
The icon at top right indicates the presence of a single
the icon
At the centre of the Home Page is a read-only parameter which can be chosen from a small set of
parameters on Page 8.0 of the menu.
From the Home Page it is possible to access the page for regulating the contrast of the display:
hold down the hidden button, then press and release the right button.
From the Home Page it is also possible to access the read-only menu of the inverter sensitive
parameters set in the factory: hold down the central button for 3 seconds.
Page 1.0
The factory settings are set from Page 1.0 by holding down the left and right buttons at the same
time for 3 seconds.
The resetting of the factory settings will be notified by the appearance of the symbol
word "Default".
Page 2.0
The regulating mode is set from Page 2.0. It is possible to choose from 9 different modes:
Page 2.0 displays the three icons which represent:

1. = Regulation with constant differential pressure
2. = Regulation with constant curve with speed set from the display.
3. = Regulation with constant curve with speed set by remote signal 0-10V.
4. = Proportional differential pressure regulation.
5. = T constant regulation increasing mode
6. = T constant regulation decreasing mode
7. = T1 constant regulation increasing mode
8. = T1 constant regulation decreasing mode
