Heat.pump.models.will.automatically.run.the.electric.heater.to.quickly.bring.the.room.up.to.temperature.when.initially.
energized,.then.return.to.heat.pump.mode...This.ensures.that.the.room.is.brought.up.to.temperature.quickly.without.the.
usual.delay.associated.with.heat.pump.units.
The.digital.control.monitors.indoor.conditions.to.ensure.that.the.room.temperature.is.within.five.degrees.of.the.setpoint...
If.necessary.the.unit.will.cycle.the.electric.heat.to.maintain.the.temperature...This.feature.ensures.guest.comfort.by.
delivering.the.heating.benefits.of.an.electric.heater.while.maintaining.the.efficiency.benefits.of.a.heat.pump.
The.owner.may.choose.between.fan.cycling.or.fan.continuous.mode.based.on.property.preference...(Note:.Even.heat.
monitoring.and.quiet.start/stop.fan.delay.only.operate.in.fan.cycle.mode).Fan.continuous.mode.is.used.to.keep.constant.
airflow.circulation.in.the.room.during.all.times.the.unit.is.'ON'...Fan.cycle.will.conserve.energy.by.only.operating.the.
fan.while.the.compressor.or.electric.heater.is.operating...The.ability.to.set.the.fan.cycling.condition.independently.
between.heating.and.cooling.mode.will.increase.user.comfort.by.allowing.the.choice.of.only.constantly.circulating.
air.in.the.summer.or.winter.time...Unlike.other.PTAC.brands.that.only.allow.one.selection.
In.the.event.of.a.compressor.failure.in.heat.pump.mode.the.compressor.may.be.locked.out.to.provide.heat.through.the.
resistance.heater...This.feature.ensures.that.even.in.the.unlikely.event.of.a.compressor.failure.the.room.temperature.can.
be.maintained.until.the.compressor.can.be.serviced.
All.Friedrich.digital.PTACs.have.low.voltage.terminals.ready.to.connect.a.desk.control.energy.management.system...
Controlling.the.unit.from.a.remote.location.like.the.front.desk.can.reduce.energy.usage.and.requires.no.additional.
accessories.on.the.PTAC.unit.
The.frost.sensor.protects.the.compressor.from.damage.in.the.event.that.airflow.is.reduced.or.low.outdoor.temperatures.
cause.the.indoor.coil.to.freeze...When.the.indoor.coil.reaches.30°.F.the.compressor.is.disabled.and.the.fan.continues.to.
operate.based.on.demand...Once.the.coil.temperature.returns.to.45°.F.the.compressor.returns.to.operation.
The.new.Friedrich.PD.series.units.feature.an.indoor.fan.system.design.that.reduces.sound.levels.without.lowering.airflow.
and.preventing.proper.air.circulation.
The.Friedrich.PTAC.benefits.from.quality.components.and.extensive.development.to.ensure.a.quiet,.efficient.and.
dependable.unit.
Friedrich's.new.dual.motor.design.allows.for.the.quietest.and.most.efficient.units.yet.
High.efficiency.rotary.compressors.are.used.on.all.Friedrich.PTACs.to.maximize.durability.and.efficiency.
Outdoor.coil.endplates.made.from.stainless.steel.reduce.corrosion.on.the.outdoor.coil.common.with.other.coil.designs.
Diamonblue.(seacoast.protection).protects.the.outdoor.coil.from.harsh.environments...Comes.standard.on.all.
PTAC.units.
All.Friedrich.PTAC.return.air.filters.feature.an.anti-microbial.element.that.has.proven.to.prevent.mold.and.bacterial.
growth.in.laboratory.testing...PDXRTA.replacement.filter.kits.feature.the.same.anti-microbial.agent...All.filter.are.
washable.and.reusable.and.are.easily.accessed.from.the.top.of.the.unit.without.the.removal.of.the.front.cover.
Friedrich.PTAC.units.are.capable.of.introducing.up.to.75.CFM.of.outside.air.into.the.conditioned.space...The.
outdoor.air.passes.through.a.mesh.screen.to.prevent.debris.from.entering.the.air.stream.
