1.7 CONTROL DEVICES UNIT.
The control unit manages the solar system by controlling the solar
unit pump. The various functions can be programmed via the 3
buttons positioned under the display.
1 Forward; 2 Reverse; 3 Set (Selection / operation mode)
The unit (A) activates the pump when a temperature difference set
between the collector probe (S1) and the boiler probe (S2) (Fig. 8).
The installation must only be carried out in closed and dry en-
vironments. To guarantee regular operation, avoid areas with
strong electromagnetic fields. The regulation control unit must be
detachable from the electric network by means of an additional
device in compliance with the Laws in force. During installation
ensure that the connection cable to the electric network and the
probe cables remain separated.
The control unit is equipped with 3 relay to which to connect users
such as pumps, valves, etc.
At the time of installation the unit is supplied pre-set for its cor-
rect use. For personalisation and installation information see the
relative instructions book.
Attention: the probes supplied are used in accordance with the
pre-fixed purpose:
S1 PT1000 solar probe
S2 NTC boiler probe.
