IMPORTANT SAFETY INFORMATION
WARNING: ELECTRICAL SHOCK HAZARD – Turn off power at the main
power source by unscrewing fuse or switching circuit breaker
to the OFF position before installing, removing, or cleaning
this thermostat.
WARNING: FIRE AND ELECTRIC SHOCK HAZARD – This device should be
installed by a qualified service technician with due regard
for safety as improper installation could result in a fire and
electric shock hazard.
WARNING: FIRE AND ELECTRICAL SHOCK HAZARD – This is a 24V AC
low-voltage thermostat. Do not install on voltages higher than
30V AC.
• Do not switch system to cool if the temperature is below 50°F (10°C). This can
damage your cooling system and may cause personal injury.
• Do not short (jumper) across terminals on the gas valve or at the system control
to test installation. This will damage the thermostat and void the warranty.
• Do not connect ground to any terminal in this unit.
• All wiring must conform to local and national building and electrical codes and
ordinances.
• Use this thermostat only as described in the manual.

keytoasuccessfuloutcome.ThestepsrequiredtoinstalltheSMART3000
thermostat are:
1. Read and understand this manual.
2. MounttheSMART3000backplateinasuitablelocation.
3. SettheeightDIPswitchestomatchtheneedoftheproject/user.
4. Connectwirestoterminalblocks.
5. Wire the optional remote temperature sensor(s) or switches if required.
6. Power up the heating/air conditioning system.
7. Settheinstallersoftwareoptions(ifrequired).
8. ProgramandsetuptheSMART3000thermostat.
9. Test the heating, cooling and other functions – Commissioning.

Mounting the SMART 3000 Thermostat
IMPORTANT: TheSMART3000canonlybeasaccurateastheonboard
temperaturesensor,oritsoponalremotetemperaturesensor(s)
permit. TheSMART3000shouldbemountedinalocationthat
is typical of the ambient room temperature. Do not install near
the floor, in a draft, behind a door, or on a non-insulated, exterior
wall.InstalltheSMART3000awayfromexposuretosunlightand
four to five feet (1.2 to 1.5 m) above the floor.
Figure 1
• Locatetheslotonthehousingatthebottom.Takenoteofthehingepoints
and the connection between the two halves.
• Insert a screwdriver or coin into the slot and twist. This will separate the
two halves.
8
• Continue to swing the top half upward. This will release the tabs holding the
top half in place.
• Pull the control wires through the large opening in the base plate.
• Position the base plate on the wall and attach it with appropriate fasteners
(two screws with drywall anchors are supplied). The base plate should be
visibly level.
• Blockanyholeswherewiresarepulledthroughawallopening.Thiswill
preventdraftsfromenteringthebackofthethermostat.
Do not use
these holes for
mounting.

Plan Your Installation
Inaddiontothestandardthermostatwiring,theSMART3000has:
• A group of DIP switches
• ModBus communication terminals
• Two terminals for using remote sensors and contacts
• RJ12 to connect to an outside door station
ResetSwitchAccessHole

Theswitchesmustbesetcorrectlyforeachsystemconguraon.Followthese
steps to create your Plan:
1. Review the settings in Table 1.
2. Read the following switch descriptions.
3. Markorwritedowntheswitchpositionsthatyouwilluse.
4. Locate the wiring diagram that accurately describes your equipment, starting
on page 18.
5. Review the switch settings next to the wiring diagram. If there are any
differences between that list and your selections, review your list. Be certain
you have the correct wiring diagram and choices for switch positions.
The ModBus and sensor terminals will be described later in this manual.
