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 (CLAMP M14, PIN 55-56, 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).

P35
SAFETY CHECK ENABLING FOR INSUFFICIENT CIRCULATION
DURING IGNITION
BY ACTIVATING THIS PARAMETER, THE CORRECT FUNCTIONING
OF THE PUMP IS CHECKED AT EACH BURNER IGNITION. THIS
CHECK ALLOWS TO PROTECT THE HEAT EXCHANGER AND
OTHER PARTS FROM EXCESSIVE NON-DISSIPATED HEAT, IN
CASE THE PUMP DOES NOT WORK PROPERLY.
