DetailedOperation
Overview
TheETSisapre‐pipedandpre‐wiredassemblythatincludestheETVPlatinumPlus(ElectronicTemperingValve)
ineitheraSimplex(singlevalve)orDuplex(dualvalves)configuration.TheETVPlatinumPlusisahotwater
temperaturecontrolcapableofoperatingoneortwoelectronicmotorizedmixingvalvestoregulatethesystem
watertemperature.Theelectronicmixingvalvesarecontrolledusingavoltageoutputmodulationsignals.Its
modulationPIDisdesignedtorespondquickly,whichmakesitsuitablefordomestichotwaterapplications.
TheETSassemblyconsistsoftheETVvalve(s)withactuator(s),ETVPlatinumPluscontrolmodule,a TMC
motorized safety valve andthreeprobe(directimmersion)sensorsontheMixedOutlet,HOT,andCOLD
pipingfromthevalve(s).
Foraddedprotection,theETSassemblyisconfiguredon a loss of power condition topower the ETV valve(s)
to a full COLD position. On conditions wherethemixedoutlettemperatureexceedstheAlarmLimit the ETS
will power the ETV valve(s) to a full COLD position and close the TMC valve on the hot water supply to the
mixing valve. In this Alarm condition the ETV module will close the alarm contacts tiggering the ETS audible
alarm and enter into a manual reset condition. For additional information on the LOCKOUT menu see page

SelectingaLocationfortheETSAssembly
SelectanappropriatelocationtoinstalltheETSassembly.Thelocationmustmeetthefollowingminimum
requirements:
• TheETSassemblyisnotintendedforoutdoorinstallation.
• KeepthedistancebetweentheETSassemblyandthewaterheatingsourcetoaminimum.Thisreduces
pipingheatlossandprovidesminimalfrictionloss.
• TheETSassemblylocationshouldbewhereleakagefromthepipingfieldconnectionswillnotcause
damagetothesurroundingarea.
• Considerthelocationofneworexistingpipingandelectrical.
RecommendedClearances
ToensureserviceabilityoftheETSassembly,thefollowingminimumclearancesmustbemet:
GeneralElectricalGuidelines
Allassembliesrequirea120Vaclinevoltagededicatedcircuitwitha12Ampcircuitbreaker.
• LeftandRightSides:18inches • Top:24inches
•Front:24inches •Rear:0inches

GeneralPipingGuidelines
• Allpipingmustmeetorexceedallapplicablelocal,state,and/orfederalguidelines,codes,regulations,and
laws.
• Supportallpipingusinghangers.DONOTsupportpipingbytheunitoritscomponents.
• Useisolationvalves(provided)toisolatetheETSassembly.
• Useunions(provided)toallowforservicingand,ifrequired,removalofthevalveandothercomponents.
• Includedrainvalves(provided)toassistinservicingoftheETSassembly.
• Useagenerousamountofpipethreadsealant.DONOTusepipethreadtape.Whenusingthevalveina
domesticwaterapplication,ensurethethreadsealantiscompliantwithdomesticwaterapplicationand
meetsNSF61requirements.

RecirculationPumpSizing
ForproperoperationoftheETS,theassemblymustbeinstalledinasystemwithconstantrecirculation.TheETS
providesadedicatedrecirculationconnection.
Foroptimumvalvefunction,itisrecommendedthatthebuildingrecirculationtemperatureisatleast7°Flower
thanthedesiredsetpointtemperature.Inaddition,itisrecommendedthattheHOTwatersuppliedtotheETV
valveisatleast20°Fabovethedesiredsetpoint.
Therecirculationpump(notprovided)mustbeproperlysizedforthefollowingrecirculationrates:
Table3:ETSRecommendedRecirculationFlowRates
Insystemswithoutabuildingrecirculationline,itisrecommendedthataflowswitch(notprovided)isinstalled.
TheflowswitchshouldbelocatedontheMIXEDoutletfieldpipingabovetheETSassembly.Activationofthe
flowswitchshouldbeatthelowestpotentialdrawofthesystem.
Referto“WiringtheFlowProve”onpage 42forwiringtotheETVPlatinumPlusmoduleforaflowswitch
(Prove).

9. ApplypowertotheETSassembly.
NOTE: Once power is supplied to the ETS it will take approximately 2 minutes to fully charge the
Lost of Power (LOP) capacitor in the ETV valve actuator(s). Once fully charge the LOP capacitor will
be able to power the actuator and position the valve to a full COLD position during a loss of power
condition.
