The boiler is set up to manage a chiller. The supply voltage oc-
curs simultaneously with the request from the Comando Amico
Remoto remote control
V2
. In the event this configuration is
used, it is necessary to jump pins 57 and 58 of connector X25
positioned on the relay board.
The CAR
V2
must be connected to terminals 41 and 44 complying
with the polarity and eliminating jumper X40.
Attention:
to prevent the chiller electronic control from dam-
age, the signal control must not be live. Interrupt a 230V relay
between the chiller and relay board as indicated in the diagram.
All the relays can be configured. Set relay 3 as "Chiller remote
activation".
