6.7 Integration with solar thermal system (only for
200 LT-S and 260 LT-S models)
The following figure (fig. 19) shows how to connect the equip-
ment to a solar thermal system controlled by a dedicated elec-
tronic controller (not supplied) that has a "voltage-free contact"
type output to be connected to the DIG.1 input of the equipment
(see "6.8.1 Remote connections").
To use the equipment in this configuration it is necessary to set
the parameter P16 = 1 (see par. 8.1).
The following figures (fig. 20 and fig. 21) show how to connect
the equipment to a solar thermal system controlled directly by
the latter, without the aid of a dedicated electronic controller.
In the configuration of fig. 20, in case of solar collector overtem-
perature a drain valve (not supplied) is activated to discharge in
a DHW storage tank (puffer) hot water contained in the equip-
ment.
In the configuration of fig. 21, however, in this condition the solar
collector shutter is closed.
In both cases this occurs in order to allow the collector to cool
down.

To use the equipment in both these configurations it is neces-
sary to set the parameter P12 = 2 and P16 = 2 (see par.8.1).
