Principle of operation
Icma solar module TAS001 is employed in the primary circuits of solar systems to manage the thermodynamic cycle
of the heat-transfer uid between the solar panels and the hot water storage tank.
In thermal solar panels the solar radiation increases the heat-transfer uid temperature and therefore its thermal
power.
In the storage tank, instead, the heat-transfer uid carries through a heat exchanger most of its heat to the water in
the tank.
The hot water in the tank will be then
used for space heating or domestic
use.
The solar module manage this
process and is equipped with a
circulator pump having proper
performances (ow and head) as
well as several regulation and control
devices that run the operation of the
circuit.

Filling the system
Technical specications
The solar module receive a signal from the external controller which, having at least two temperature sensors (one
is positioned on the panel outlet pipe and the other is an immersion sensor in the boiler), constantly reads the
temperature dierence and keeps it within the established range, which normally varies between 5 and 8 °C. If the
Δt between the panel and the boiler is found to be over the established set point, the controller starts up the pump
on the module to provide the lacking thermal load. If, on the other hand, the Δt is narrower than the one set, the
internal pump will be disabled.
For further clarication about the electronic controller functioning, consult the technical documentation about
art. S303 and S305.
1. Open the shut o valves connected with the air vent valves (Pict.1). These valves must be located at the highest
point of the system to optimize their function of air expulsion from the circuit.
2. Open both the shut o valves 4 and 8 (Table1-page 3) turning their handles to 45° (see the operating specications
of these valves on pagee 11 of
this data sheet).
3. 3. Fully open the ow meter 7
(Table1-page 3) carrying the
reference mark of the ow
meter in vertical position (see
operating specications on
page 10). Check that the drain
tap 3 is closed.
4. 4. Connect an external pump
to the tap 3 of the instrument
holder connection 2 (Table1-
page 3) with a rubber pipe. This
pump will get the heat-transfer
uid, previously prepared, from
an external container.
5. 5. Open the tap 3 of the
instrument holder connection
2 (Table1-page 3) and start the
external pump to ll the system

Shut/o valve and check valve
Deaerator
The group is equipped with shut-o valves with thermometer and built-in check valve 4 and 8 (Table1-page 3). The
valves intercept the delivery and return ow to let ll, wash and discharge the system. They also enable a quick and
easy replacement of the pump without emptying the system.
The shut-o valves are also equipped with check valves which ensure the proper ow of the heat-transfer uid inside
the solar circuit preventing undesired reuxing when the pump is not working
1. To fully close the shut-o valves turn the regulatig handles clockwise until they stop (Pict.5).
2. To allow the uid to pass through the valves in both directions and open the check valve, turn the regulating
handles to 45° (Pict.6).
3. During the normal operating cycle instead, the valves must be in the position shown in Pict.7 by turning the
regulating handles counter-clockwise until they stop.
The solar modules S001, S002, and S004 is equipped with a deaerator 9 (Table1-
page 3).
During the normal functioning of the solar circuit, the air present in the heat-
transfer uid is separated and collected in the upper part of the deaerator.
During the start-up, the air collected in the deaerator has to be periodically
discharged by the manual air vent located in the upper part of the deaerator
by turning its spindle counter-clockwise with a screwdriver. After discharging
all the air in the deaerator, close the vent by turning its spindle clockwise until
it stops.
Once the star-up is completed, for a rst period, this operation must be repeated
every month.
Then it will be sucient to repeat this operation every 6 months to mantain the
solar system ecient.
