Type OTN2 / OTD2 with room or floor sensor
Pollution class: 2
Pollution.class.2,.representative.of.air.circulation.in.typical.homes..
Overvoltage category: III
Pulse.voltage.4.kV.to.IEC.60664-1.
Sensor installation
Floor sensor:
The.floor.sensor.should.be.installed.in.standard.conduit.embedded.
in.the.floor..The.conduit.should.be.sealed.and.positioned.as.close.
to.the.floor.surface.as.possible..
Room sensor:
The.room.sensor.should.be.installed.in.a.standard.wall.box.or.
mounted.direct.on.the.wall..Sensor.cables.can.be.extended.up.to.a.
maximum.of.50.m.in.length.using.power.cable..Two.wires.in.a.multi-
wire.cable.must,.however,.not.be.used.if.the.cable.is.also.used.to.
supply.power.to.heating.cables..The.best.result.is.achieved.if.a.se-
parate.cable,.installed.in.a.separate.conduit,.is.used.for.the.sensor.
Installation of thermostat
Built-in or external room sensor
The.thermostat.or.external.room.sensor.should.be.mounted.on.a.
wall.in.such.a.way.as.to.allow.free.air.circulation.around.it..It.must.
also.be.positioned.so.as.to.prevent.it.from.being.affected.by.direct.
heat.sources.(e.g..the.sun),.draughts.from.doors.and.windows,.or.
outside.temperature.(i.e..do.not.mount.on.outer.walls)..MICRO-
LINE.has.a.built.in.fault.circuit.which.switches.the.heating.off.if.the.
sensor.is.disconnected.or.short-circuited.
Thermostat installation
-.. Open.cover.
-.. Unscrew.cover.and.remove..
-.. Connect.wires.from.rear.as.shown.in.wiring.diagram.
-.. Mount.thermostat.in.wall.box.-.fit.frame.and.cover.

Temperature setting
Interrupter
MICROLINE.has.a.temperature.setting.range.of.0-40°C.
Set.the.wanted.temperature.with.the.arrow.buttons,.the.set.tempe-
rature.shows.in.the.display...The.thermostat.will.calculate.the.best.
way.to.control.the.heating.system.in.order.to.achieve.the.desired.
temperature..If.necessary,.fine.adjustment.can.be.performed.after.
1.or.2.days..
Night setback
The.night.setback/economy.temperature.function.is.activated.via.
a.230.V.signal.from.an.external.timer.connected.to.terminal.S.
The.function.is.factory.set.to.5°C.(2-8°.OTD2)..The.LED.lights.green.
when.the.economy.signal.is.active.and.red.when.heating.is.active.
Frost protection
If.the.signal.is.connected.via.a.rectifier.diode,.the.thermostat.will.
maintain.a.floor/room.temperature.of.5°C.
Settings
