1. COMPONENT DESCRIPTION
Firstbox is a modular system that allows the realisation of high tem-
perature (radiators, fan coils) and low temperature zone systems (floor
systems) and makes it possible to connect several modules to one another
as needed; In fact, besides standard pre-assembled built-in modules,
individual modules allow the construction of the distribution system that
best suits your needs; the open manifold installed upstream from the zone
distribution modules hydraulically separates the primary circuit from the
secondary circuits.
Firstbox allows the individual circuits with the pumps turned off to be
excluded thus avoiding recirculation and parasite currents that keep the
terminals and the floor system supply circuits warm when the pumps are
not running. Through the use of electrical boxes for the wiring of high and
low temperature circulator pumps (not included as standard), controlled by
the zone room thermostats, it is possible to automate the management of
First Box (see diagram on page 28)).
In the models with electronic climatic adjustment, the automatic manage-
ment of the single low temperature zone is carried out by the climatic
adjustment device which is controlled by the room thermostat and acts
directly on the servomotor of the mixer valve excluding the zone circuit
with the circulator pump off.
Version with set point adjustment.
