By.digitally.monitoring.desired.room.temperature.the.room.is.controlled.more.precisely.than.conventional.systems...
The.large,.easy.to.read.LED.display.can.show.either.set-point.or.actual.room.temperature.as.selected.by.owner.
When.the.unit.is.powered.off.the.unit.can.be.returned.directly.to.heating.or.cooling.mode.by.pressing.the.'Heat'.or.
'Cool'.buttons.without.the.confusing.power.up.sequence.of.some.controls...One-touch.control.takes.guesswork.out.
of.unit.control.delivering.a.more.enjoyable.experience.and.eliminating.front-desk.calls.
The.Friedrich.PTAC/PTHP.units.feature.three.fan.speeds.for.the.user.to.select.from...This.allows.the.user.to.
properly.match.the.amount.of.airflow.for.their.comfort.level.and.also.deliver's.quiet.performance.
By.having.separate.control.buttons.and.indicators.for.both.fan.and.mode.settings.the.Friedrich.digital.control.
eliminates.the.confusion.of.previous.digital.PTACs...The.accurate.temperature.setting.provides.greater.guest.
comfort.than.other.systems.
The.fan.start.and.stop.delays.prevent.abrupt.changes.in.room.acoustics.due.to.the.compressor.energizing.or.
stopping.immediately...Upon.call.for.cooling.or.heating.the.unit.fan.will.run.for.five.seconds.prior.to.energizing.the.
compressor...Also,.the.fan.off.delay.allows.for."free.cooling".by.utilizing.the.already.cool.indoor.coil.to.its.maximum.
capacity.by.running.for.30.seconds.after.the.compressor.
When.connected.to.a.wall.thermostat.the.user.can.select.from.high.or.low.fan.speed.at.the.thermostat,.unlike.
competitive.models.that.have.only.one.speed.selection...This.allow.more.comfortable.and.quieter.operation...
Requires.the.use.of.Friedrich.remote.thermostat.RT6.or.equivalent.thermostat.with.two.speed.fan.output.
Some.applications.require.the.use.of.a.wall.mounted.thermostat...All.new.Friedrich.PTACs.may.be.switched.from.
unit.control.to.remote.thermostat.control.easily.without.the.need.to.order.a.special.model.or.accessory.kit.
The.Friedrich.digital.PTAC.features.a.self.diagnostic.program.that.can.alert.maintenance.to.component.failures.
or.operating.problems...The.internal.diagnostic.program.saves.properties.valuable.time.when.diagnosing.running.
problems.
The.self.diagnosis.program.will.also.store.error.codes.in.memory.if.certain.conditions.occur.and.correct.
themselves.such.as.extreme.high.or.low.operating.conditions.or.activation.of.the.room.freeze.protection.feature...
Storing.error.codes.can.help.properties.determine.if.the.unit.faced.obscure.conditions.or.if.an.error.occurred.and.
corrected.itself.
By.limiting.the.operating.range.the.property.can.save.energy.by.eliminating."max.cool".or."max.heat".situations.
common.with.older.uncontrolled.systems...The.new.electronic.control.allows.owners.to.set.operating.ranges.for.
both.heating.and.cooling.independently.of.one.another.
When.the.PTAC.senses.that.the.indoor.room.temperature.has.fallen.to.40°.F.the.unit.will.cycle.on.high.fan.and.
the.electric.strip.heat.to.raise.the.room.temperature.to.46°.F.then.cycle.off.again...This.feature.works.regardless.
of.the.mode.selected.and.can.be.turned.off...The.control.will.also.store.the.Room.Freeze.cycle.in.the.service.code.
memory.for.retrieval.at.a.later.date...This.feature.ensures.that.unoccupied.rooms.do.not.reach.freezing.levels.
where.damage.can.occur.to.plumbing.and.fixtures.
Multiple.compressors.starting.at.once.can.often.cause.electrical.overloads.and.premature.unit.failure...The.random.
restart.delay.eliminates.multiple.units.from.starting.at.once.following.a.power.outage.or.initial.power.up...The.
compressor.delay.will.range.from.180.to.240.seconds.
The.Friedrich.PTAC.uses.a.digital.thermostat.to.accurately.monitor.the.outdoor.coil.conditions.to.allow.the.heat.
pump.to.run.whenever.conditions.are.correct...Running.the.PTAC.in.heat.pump.mode.saves.energy.and.reduces.
operating.costs...The.digital.thermostat.allows.maximization.of.heat.pump.run.time.
