3-WaY ValVe
The.3-way.valve.is.activated.by.the.controller.(if.present.and.connected.to.the.controller,.as.described.in.Chapter.DISPLAY.CONNECTION).with.
the.device.ON.and.when.the.temperature.detected.by.probe.i1.exceeds.the.value.set.for.THRESHOLD.OUT1=60°C.(PR01).and.the.boiler.is.in.
the.demand.status..It.is.disabled.when.the.temperature.detected.by.probe.i1.drops.below.the.value.set.for.THRESHOLD.OUT1=60°C.less.the.
hysteresis.value.DELTA.OUT1=5°C.(PR02),.i.e..below.55.°C.or.when.required..(See.diagrams.3,.4,.7,.8
BoileR aCtiVe
Activate. the. boiler. by. setting. parameter. PR08=ON. and. connecting. probe. i3. Optional. (L=. 2. metres). as. described. in. Chapter. DISPLAY.
CONNECTION.
The.boiler.enters.the.request.status.with.the.device.ON.until.the.temperature.detected.by.probe.i3.reaches.the.SET.BOILER.MAX=60°C.(PR09).
value,.at.which.point.the.request.is.fulfilled..The.boiler.returns.to.the.request.status.when.the.temperature.detected.by.probe.i3.drops.below.
the.SET.BOILER.MIN=30°C.(PR10).value..(See.diagrams.3.and.4)..
PUFFeR aCtiVe
Activate. the. puffer. by. setting. parameter. PR11=ON. and. connecting. probe. i2. Optional. (L=. 2. metres). as. described. in. Chapter. DISPLAY.
CONNECTION.
The.puffer.enters.request.status.with.the.device.ON.until.the.difference.between.the.temperature.detected.by.i1.and.that.detected.by.probe.
i2.is.greater.than.the.DT.ON=7°C.(PR12).value..When.the.same.difference.drops.below.the.DT.OFF=5°C.(PR13).value,.the.puffer.exits.from.the.
request.status..(See.diagrams.5.and.6).
BoileR anD PUFFeR aCtiVe
When.both.the.boiler.and.the.puffer.are.active,.the.parameters.of.point BOILER.ACTIVE.and.PUFFER.ACTIVE.remain.active..Via.the.3-way.valve,.
the.controller.gives.priority.to.the.boiler's.request;.once.complete,.it.responds.to.the.puffer's.request..(See.diagrams.7
eleCtRiC ConneCtion
See.Chapter.DISPLAY.CONNECTION.
The.control.unit.and.the.plant.must.be.installed.and.connected.by.authorized.personnel.according.to.the.standards.in.force.
all operations must be performed with mains power disconnected.
Connect.the.feeding.cable.of.the.switchboard.with.an.electronic.bipolar.switch.respecting.at.least.a.3.mm.distance.between.the.contacts..
Power.supply.230V~..50./.60.Hz,.it.is.necessary.to.provide.for.the.correct.connection.to.the.grounding.plant.
WaRning:.The.control.unit.must.be.connected.to.the.mains.with.a.differential.line.cut-off.switch.according.to.the.regulations.in.force..Correct.
operation.of.the.appliance.is.only.guaranteed.for.pumps.and.valves.approved.by. noRDiCa S.p.a... noRDiCa S.p.a..is.not.liable.for.any.
