performed.

DISPLAYING TEMPERATURES AND ENERGY PRODUCED

The alphanumeric display of the power unit will normally
show the temperature detected by the probes connected
as well as the quantity of energy produced. The energy will
be expressed in K h + M h. The counting of K h when
reaching 1 K h will be set to zero and the M h counter
will increase by 1. The addition of the two counters will give
the total energy produced (i.e. 15 K h + 12 M h
M h). Press ' ' or ' ' to cyclically select the probe of
which you need to see both the temperature and the quantity
of energy produced:

DISPLAYING SUN / ANTI-FREEZE

uring normal operation the 'SUN' icon will be always lit on
the display. hen the power unit detects a condition which
forces the manifold pump to get started the 'SUN' icon will
be ashing.
hen the Anti-freeze function is activated both 'SUN'
and 'SNO ' icons will be lit; when the power unit detects
a temperature which forces the anti-freeze function to get
started the 'SNO ' icon will also be ashing.

Visualization of this parameter is available only for
version with variable collector pump speed.
If the ' ' or ' ' keys are pressed during normal operation
the central unit will not only show the temperature as read
by the connected probes but it will also display the solar
collector pump speed as a percentage.
As regards the FS2 parameter the power unit will show
this parameter set at if the OUT2 outlet is not connected.
Alternatively if the selected installation diagram does not
require installation of a collector pump at outlet OUT2 this
parameter will only be displayed with the values
