Outputs.
Such single-pole relay controls the pump (M1) and is actuated when pump operation is
required.
Pump relay
(K3)
Such bi-polar relay is enabled when the burner needs to be ignited. Boiler ignition is
enabled when it makes contact.
Request relay
(K2)
It is a continuous current signal which controls the modulation coil and allows for varying
of gas pressure at the burner depending on requested heat output.
Gas valve modulating coil
(Y2)
This signal signals to the zone control unit the current status of the appliance (DHW/
central heating) and, when installed it recognizes the CAR as room thermostat for no.1
zone (see Zone Control Unit function).
Zone control unit (CZ)
(option boiler externally
installed)
Such (BUS) signal displays boiler temperature, DHW or central heating function mode,
the codes of any activated alarms and the temperature reading of outdoor probe on the
remote control display.
Comando Amico Remoto
remote control (CAR) (op-
tion) (see CAR function)
Such relay powers the motor (M) on electric 3-way valve (M30).
It is enabled after a central heating request and idles when there is a DHW request.
3-way valve relay
(K1)
It is a 230 V AC signal indicating the main coils on the gas valve
(Y1) are being powered.
Gas valve supply
(Y1)
230 V AC =
Powered coils
0 V AC = No
Powered coils
It is a high voltage signal (more than 16 kV) which triggers an electrical spark at either end
of the ignition electrodes on the burner.
Ignition electrodes
(E1)
It is a signal that allows the circuit board to communicate with external devices (e.g.
ImmergasVirgilio palmtop).
BUS output
(external optional)
It is a unipolar relay for the control of the fan (M20) which is excited when its operation
is requested.
Fan relay
(K4)
It is a signal (BUS) which allows to show on the remote control display, the boiler
temperature, operation in domestic hot water or central heating mode, the codes of
the alarms that have intervened and the temperature detected by the eventual external
probe.
Super CAR
(optional)
(see CAR oiperation)
