INSTALLATION INSTRUCTIONS

STEP 1 – INSTALL SENSOR BASED ON THE APPLICATION

Return Air Temperature

• LocatetheAprilaireModel8052sensorinthereturnat

least 6" upstream from the fresh air intake so the fresh air

does not influence the sensor reading (see FIGURE 2).

• Drilla3/8"holeintheductandmountthesensorwiththe

supplied screw and mounting bracket (see FIGURE 1).

Leaving Air Temperature

• LocatetheAprilaireModel8052sensorinthesupplytrunk,

after the heat exchanger and cooling coils (see shaded

area in FIGURE 2).

• Shieldormountawayfromdirectradiationsourcessuchas

sunlight, UV lights, heat exchangers or cooling coils.

STEP 4 – WIRE THE SENSOR TO THE APRILAIRE CONTROL

• Use18–22awgwire(2-wirethermostatcable).

• Usethetwosmallwirenutsprovided.

• Uselessthan300'ofwire.

• Donotroutewirealong120VAClines.

CAUTION

Excessive bare wire can lead to shorts.

Strip only as much insulation as is necessary.

• Thesensorisnotpolarityspecific.Eithersensorleadmaybe

connected to either terminal on the Aprilaire control to which it

is wired.

 – Forsupportmodules,useT1andT2orT3andT4terminals.

 – Forthermostats,useS1andS2(Outdoor)orT1andT2(Remote)

terminals.

 – Forzonecontrols,useDAT,PlenumSensororODTterminals.

 – ForHomeComfortControl,useRAT,LATorODTterminals.

• Usecarewhenroutingandstrippingthewire.Sharpbends(kinks)

orcutsinthewire(particularlysusceptiblewheretheinsulationhas

beenstripped)canleadtoeventualconductorfailure.

STEP 5 – RECONNECT POWER TO THE APRILAIRE CONTROL

Sensor Specifications:

Resistance@77°F(25°C):10k

Tolerance@77°F(25°C):±3%

STEP 2 – DISCONNECT POWER TO THE APRILAIRE CONTROL TO

WHICH THE SENSOR WILL BE WIRED

CAUTION

Damage to components can occur if power is not disconnected.

STEP 3 – VERIFY THE SENSOR RESISTANCE

Useanohm-meterormultimetertomeasuretheresistanceofthe

sensor.MeasureatthewiresneartheAprilairecontroltocheckany

wiresplices.Confirmtheresistancecorresponds(within5%)tothe

temperature where the sensor is installed.
