WIRING DIAGRAM WITH ACTIVE SYSTEM PHASE
AND GENERIC ALARM.
The unit is set up for the management of any external pump;
the pump is powered in concomitance with the request phase
on the system.
All the relays can be configured as an active system phase; the
diagram represents the connection on relay 2. In the event this
relay is used, it is necessary to jump pins 57 and 58 of connector

WIRING DIAGRAM WITH PUFFER MODE ACTIVE.
The device is set up for the management of any pre-heated puffer.
During a request for heating, in case the heating probe detects
a temperature higher than the one requested, the system circu-
lating pump is activated while the generator is kept off.

In addition, the possible connection to relay 1 is represented.
The device is set up for the management of any generic alarms.
All the relays can also be configured as generic alarm. The ''ge-
neric alarm'' signal is enabled whenever one of the envisioned
anomalies occurs in the device (see device book under ''Trou-
bleshooting'').
All the relays can be configured as an active puffer mode active;
the diagram represents the connection on relay 2. In the event
this relay is used, it is necessary to jump pins 57 and 58 of connec-
tor X25 positioned on the relay board. Activation of the Puffer
mode active excludes the activation of the third zone mode.
