Installation



Aswithanyairconditioningprojectundertaken,carefulinstallationisthekeytoa

successfuloutcome.Timetakenduringthisinstallationprocesswillberewardedwitha

happycustomerandfewercall‐backs.



ThestepsrequiredtoinstalltheSMT‐770thermostatare‐



1. ReadandunderstandthismanualandtheUsermanual.

2. MounttheSMT‐770backplateinasuitablelocation.

3. Setthe8DIPswitchestomatchtheneedoftheproject/user.

4. Wiretheoptionalremotetemperaturesensor(s)orswitchesifrequired.

5. Poweruptheairconditioningsystem.

6. Settheinstallersoftwareoptions(ifrequired).

7. ProgramandsetuptheSMT‐770thermostat.

(TheUserManualwillassistwiththis).

8. Testtheheating,coolingandotherfunctions–Commissioning.



Forconveniencethelayoutofthismanualisinthesameorderasthestepslistedabove.



MountingtheSMT‐770thermostat.

TheSMT‐770canonlybeasaccurateastheonboardtemperaturesensor,orits

optionalremotetemperaturesensor(s)permit.ItisthereforeessentialthattheSMT‐

770beinstalledinalocationthatistypicaloftheambientroomtemperature.Donot

installthethermostatinadraft,nearafloor,behinddoorsoronanon‐insulated

externalwall.Alsoavoidplacingthethermostatinareaswheretheairmovementis

limited,affectedbydirectsunlightorotherareasnot“typical”ofthetemperatureof

theroom.



Further,whenmountingtheSMT‐770beawarethatdrafts

maytraveldowntheinsideofcavitywalls,(especiallyif

mountedonexternalwalls)andenterthebackof

thethermostatorsensorenclosurethroughthe

cableentryholesinthewall.Itisimportanttofully

sealtheseholestopreventanydraftsaffectingthe

internallymountedtemperaturesensor.Itis

recommendedtomounttheSMT‐770orremotesensors

between1.5&1.7metresfromthefloorwherepossible.



Movethecontrolwiresthroughthelargeopeninginthethermostatbaseplatethen

placethethermostatbaseonthewallandusingappropriatescrews,firmlyattachthe

thermostatbasetothewall.Blockanyholeswherecablesenterthebackofthe

thermostattopreventdraftsenteringthroughtheseholesaffectingthesensor.



Switch7–MinimumRunTime.

ToconserveenergyandprotecttheA/Csystemitisrecommendedtolimitthenumber

oftimestheheatingand/orcoolingsystemcanrunin1hour.Thisswitchsetsthe

minimumheatingandcoolingequipmenttoaminimumruntimeof2or6minutes.

Oncetheheatingorcoolinghasstarteditmustrunforthisminimumsettime.TheLCD

TTTerminalFunctions



TheSMT‐770isfittedwithasetofterminalsmarked“TT”.Detailsonthefunctionsthat

the“TT”terminalsperformisprovidedbelow.Seetheadvancedinstallersettingmenu

usedinthefollowingexamplesarenotpolaritydependentanddonotnormallyrequire

screenedcable.



Note:TheSMT‐770canusemultiplesensorsifrequiredforaveraging.
