so that the installer can verify the accuracy of the wirings

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

when

reaching 1

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

12.15

h). Press ‘

‘ or ‘

‘ to cyclically select the probe of

which you need to see both the temperature and the quantity

of energy produced:

COL

S_2

S_3

S_4

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

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.

DISPLAY OF COLLECTOR PUMP SPEED

WARNING!

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

(outlet

.) or 1

(outlet N.C.)

i.e. it will work as an ON /OFF

type outlet.

AUTOMATIC / MANUAL / ABC (Automatic Boiler Control)

OPERATION

The control unit can manage the installation selected in 3

different modes:
- AUTOMATIC: in this mode the control unit automatically
