ELECTRONIC BOARD

Built. according. to. Low. Voltage. directive.
2014/35/UE.and.powered.at.230.Volt,.via.
a. transformer. it. sends. 24. Volt. power. to.
the. following. components:. gas. valve,.
safety. thermostat,. heating. probe,. water.
pressure. transducer. and. air. pressure.
switch.
An. automatic. and. continual. modulation.
system.permits.the.boiler.to.adjust.power.
to.the.various.system.or.user.needs.
Electronic. components. are. guaranteed.
to. operate. in. a. temperature. range. from.
0.to.+60°C.

ctions.are.indicated.in.fig..14.
3.1.2 Devices
The.electronic.board.is.equipped.with.the.
following.devices:
–. "POT. RISC." trimmer (10.fig..15)
. Adjusts.maximum.heating.power.
. To.increase.the.value,.rotate.the.trim-
Module. are. electrically. connected. to. the. terminal.
board.in.the.shunt.box.
Insert. the. rubber. pipe. of. the. module. that. has. to. be.
connected. into. the. corresponding. hole. on. the. box.
wall..Perform.the.wiring.connections.to.the.junction.
box.as.shown.in.the.layout.of.figure.7/b..
Fix. the. rubber. pipe. to. the. internal. wall. of. the. box.
using.the.straps.provided..
mer.clockwise,.to.reduce.it,.rotate.the.
trimmer.counter-clockwise.
–. "POT. ACC." trimmer (6.fig..15)
. Trimmer.to.vary.the.gas.valve.ignition.
pressure. level. (STEP).. According. to.
the. type. of. gas. the. boiler. is. designed.
for,. the. trimmer. must. be. adjusted. to.
achieve. a. burner. pressure. of. appro-
ximately. 6.5. mm. H O. for. methane.
2
gas. and. 9.5. mm. H O. for. propane. gas.

(G31).
. To.increase.pressure,.rotate.the.trim-
mer. clockwise,. to. reduce. it,. rotate.
the. trimmer. counter-clockwise.. The.
slow.ignition.pressure.level.can.be.set.
during. the. first. five. seconds. after. the.
burner.is.lit.
After setting the ignition pressure
level (STEP) according to the type of
gas, make sure that the heating gas
pressure is still the previously set
value.
–. ."ANN. RIT." connector (5.fig..15)
. The. electronic. board. is. programmed,.
during.heating,.with.a.technical.burner.
delay. of. about. 90. seconds. that. is. per-
formed. both. at. cold. start. and. subse-
quent.ignitions..This.is.to.prevent.rapid.
Remove. the. two. upper. screws. from. the. shunt.
box. supplied. with. the. box. and. adjust. the. box.
cover.downwards..Remove.the.black.orifice.cap.
and.insert.regulator.RVA.47..Connect.regulator.
RVA. 47. to. the. power. supply,. as. shown. in. the.
layout. of. Figure. 7/b.. After. completing. the. con-
nection,.close.the.box.cover..
ignitions. and. shutdowns. that. could,.
in. particular,. occur. in. systems. with.
high. load. losses.. Each. time. the. boiler.
restarts,. after. the. slow. ignition,. for.
about.1.minute.it.will.run.at.minimum.
modulation. pressure. before. moving. to.
the. set. heating. pressure.. The. addi-
tion. of. a. bridge. will. cancel. both. the.
programmed. technical. delay. and. the.
minimum.pressure.operating.period.at.
ignition..In.this.case,.the.time.between.
shutdown. and. the. next. ignition. will.
depend. on. a. 5°C. differential. detected.
by.the.heating.probe.(SM).
–. DIP SWITCH (13.fig..15)
. For.correct.module.operations,.the.dip.
switches.must.be.positioned.as.indica-
ted.below:
–. "Modureg Sel." connector (14.fig..15)
. The.bridge.must.always.be.connected.
–. "Albatros" connector (15.fig..15)
. The.bridge.must.always.be.off.
