Display of pressure
BAR
Pressure
Display range: 0 ... 10 bar
Indicates the current system pressure.
note:
The pressure will only be indicated if an RPS
sensor is used.
Display of speed
n1 % , n2 % , n3 %
Current pump speed
Display range: 30 ... 100 %
standard pump;
20 ... 100 % HE pump
Indicates the current speed of the corresponding pump.
Operating hours counter
h R (1, 2, 3, 4)
Operating hours counter
The operating hours counter accumulates the solar ope-
rating hours of the relay (h R1 / h R2 / h R3 / h R4). Full
hours are displayed.
The accumulated operating hours can be set back to 0. As
soon as one operating hours channel is selected, the symbol
is displayed.
Î
In order to access the RESET-mode of the counter, press
the set button
5
.
The display symbol
will flash and the operating hours
will be set to 0.
Î
Confirm the reset with the set button
5
in order to
finish the reset.
In order to interrupt the RESET-process, do not press any
button for about 5 s. The display returns to the display mode.
Display of flow rate
L/h
Flow rate
Display range: 0 ... 9999 l/h
Indicates the measured current flow rate in the solar
system. The flow rate value is used for calculating the heat
quantity supplied (V40 / VFS).
TSFB, TRET, TSTR,
TFHQM, TRHQM,
TSFL(VFS), TSRE (RPS)
Other measured temperatures
Display range: -40 ... +500 °F
Indicates the current temperature at the corresponding
sensor. The display of these temperatures depends on the
system selected.
• TSFB
: Temperature solid fuel boiler
• TRET
: Temperature heating return
• TSTR
: Temperature tank return preahting
• TFHQM : Temperature flow (HQM)
• TRHQM : Temperature return (HQM)
