Installation Instructions
8062TrH Support Module
Application
TheAprilaire 8062is designedto offer versatility in climate control. A setof onboarddip switchesallows you to select whetheryou want asmanyastwo sensorinputsper support moduleto control, monitor or evendo a combinationof both. This temperature/humiditydatais sentby digital communicationsbackto anAprilaire 8870Communicating Thermostat,allowing you to accuratelycontrol andmonitor temperature/humidityin a given areaor multiple areas.The Aprilaire 8870CommunicatingThermostatcansupportup to four SupportModules(TrH or Tf).
Single Support Module Installation
Install the Aprilaire thermostataccordingto the instruction manualsuppliedwith it. Checkto ensurethat thermostatis operating(display showscorrecttemperature).
CAUTION: Removethe thermostat from the subbase before wiring the support module to avoid damagefrom live wire.
2.Choosethe wall locationwherethe TrH modulewill be mounted.Locatein anareafree from drafts. Do not mount supportmoduleon an exteriorwall. Run
3.Openthe supportmodulecaseby pulling the coverstraight forward.

4.Removethe circuit boardfrom the baseby pulling backthe latchthatholds it at the bottomcenter.
s.Usethe subbaseasatemplateto mark the mountinghole locationson the wall. The word "TOP" will be written in the subbase.Positionthe subbasesothat the wires canbe pulledthroughthe hole in the top
If sideaccessis preferredfor wiring, clip out the sidevents at the locationsshownbelow.

6.Snapthe circuit boardback into the subbaseby sliding the top of the boardin first andthensnappingdown on the bottom. Checkto be surethatthe latchholdsthe board properly.
7. Strip '/inch. of insulationfrom the four wires at the support module. Install the wires in the terminalslabeledRSR, RSC,RSB andRSA. Onetwistedpair of wires shouldbe usedfor the RSRandRSCconnectionandanotherpair of twistedwires shouldbe usedfor the RSB andRSA connection.Pushthe extrawire backinto the wall cavity. Sealthe hole in the wall aroundthe cableto eliminateany draft that might affectthe sensor.
8. Connectthe wires on the thennostatsubbaseto the terminalslabeledRSR,RSC,RSB andRSA. Make sure thateachterminalon the supportmoduleis wired to the terminalwith the samelabelat the thennostat.
9. If necessary,changethe TrH supportmoduledip switch settings.Note: switchesmustbe setprior to poweringthe supportmodule(supportmoduleis poweredwhen thennostatis returnedto its base). If switchesneedto be changedafterpoweringthe supportmodule,the thennostat mustbe removedfrom its basefor a minimum of 15 secondsto ensureproperresetof the supportmodule.
10.Mount the thennostaton the subbaseandconfinn that it is displayingthe correcttemperatureor humidity.
