CONNECTABLE PARTS (SOL VERSION)
The specific components of the solar system controllable by
the unit's controller are:
B
= solar circuit pump
C
= excess heat dissipating valve *
H
= collector temperature sensor
*
: this consent is activated when a critical temperature read by
the probe placed in the hottest part of the panel is exceeded .
This signal can be used in different ways, such as opening a
radiance control shutter, opening a valve in a heat dissipation
system or opening a system discharge valve .
The value at which this consent is activated is among the
parameters settable by the installer .
The characteristics of the connections are given in the table .
