P23
DISABLEMENT OF DOMESTIC HOT WATER LINE BY
MEANS OF SWITCH (ONLY FOR FAST BOILERS)
BY ENABLING THIS PARAMETER IN THE PRESENCE
OF A CONNECTION (FOR EXAMPLE A BOILER CLOCK
OR A TEMPERATURE THERMOSTAT) ON BOILER
CLOCK SWITCH ON THE BOARD, THE REQUEST FOR
BURNER IGNITION ON THE DOMESTIC HOT WATER
LINE WILL BE DISABLED UPON BOILER CLOCK
SWITCH CLOSURE.
EXAMPLE 1:
WITH THE BOILER CLOCK SWITCH
OPEN, UPON THE REQUEST FOR DOMESTIC HOT
WATER, THE FLOW SWITCH AND THE BOILER WILL
TURN ON.
EXAMPLE 2:
WITH THE BOILER CLOCK SWITCH
CLOSE, UPON THE REQUEST FOR DOMESTIC HOT
WATER, THE FLOW SWITCH AND THE BOILER WILL
NOT TURN ON.

P24
ACTIVATION OF THE AUXILIARY RELAY ON THE
“SVZ” P.C.B. (SEE CHAPTER: OPTIONAL ELECTRICAL
CONNECTIONS)
THROUGH THIS PARAMETER IT IS POSSIBLE TO
MANAGE THE TYPE OF FUNCTIONING OF THE
AUXILIARY RELAY ON THE “SVZ” P.C.B. (CLAMP M4,
PIN 5-6).
WHEN THE VALUE OF THE PARAMETER IS SET TO ‘3’,
THE ENABLING OR DISABLING OF THE AUXILIARY
RELAY IS GIVEN BY THE “TP” CONTACT (SEE
CHAPTER: OPTIONAL ELECTRICAL CONNECTIONS).
WHEN THE “TP” CONTACT IS OPEN, THE RELAY
STAYS ENERGIZED (WORKING RECIRCULATION
PUMP) WHILE WHEN THE “TP” CONTACT IS CLOSED,
THE RELAY IS DE-ENERGIZED (NOT WORKING
RECIRCULATION PUMP).
