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by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wallcontroller

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wall

thermostat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.Seal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
