2.7.4 Chronothermostat connection
Connect.the.chronothermostat.as.indica-
ted.in.the.boiler.electrical.diagram
.
(see
figs. 9 - 9/a)
after. having. removed. the.
existing.bridge..
The. chronothermostat. to. be. used. must.
be.of.a.class.conforming.to.the.standard.
EN.607301.(clean.electrical.contact).
2.7.5
Climatic regulator CR 53
connection (optional)
The.boiler.is.designed.for.connectio
.
to.a.
climatic. regulator,. supplied. on. request.
(code.8092227),.for.the.management.of.a.
heating.circuit..
The. electronic. card. will. continue. to.
manage. information. visualisation,. the.
setting. of. the. sanitary. set. and. the. hea-
ting.of.the.second.circuit,.and.the.boiler.
parameters.by.means.of.the.keys.on.the.
control.panel..For.installation.and.use.of.
the.climatic.regulator,.follow.the.instruc-
tions.included.in.the.packaging.
NOTE: Reset parameter 10 to 2 (PAR 10
= 2).
2.7.6
Remote control CR 73
connection (optional)
The.boiler.is.designed.for.connection.to.a.
remote.control.unit,.supplied.on.request.
(code.8092226)..
The.remote.control.unit.CR.73.allows.for.
complete. remote. control. of. the. boiler,.
except.release.of.the.boiler..
The.boiler.display.will.show.the.following.
message:
For. installation. and. use. of. the. remote.
control,. follow. the. instructions. in. the.
package.
NOTE: Ensure PAR 10 set to 1 (PAR 10
= 1).
2.7.7
Use with different
electronic systems
Some.examples.are.given.below.of.boiler.
systems. combined. with. different. elec-
tronic. systems.. Where. necessary,. the.
parameters. to. be. set. in. the. boiler. are.
given.. The. electrical. connections. to. the.
boiler. refer. to. the. wording. on. the. dia-
grams.(figg..9-9/a)..The.zone.valve.con-
