GETTING STARTED
As with any HVAC project, careful installation is the key to a successful outcome.
Time taken during the installation process will be rewarded with fewer call-backs.
The steps required to install the SMART 1000 thermostat are as follows.
1. Read and understand this Installation Manual and Owners Manual.
2. Mount and wire the subbase.
3. Install the batteries.
4. Set the 4 system switches to match the equipment application.
5. Wire optional remote temperature sensor(s).
6. Power the thermostat
7. Set the Advanced Installer settings.
8. Test the thermostat.

INSTALLING THE THERMOSTAT
DISASSEMBLY
There are two release slots located on the bottom of the thermostat. Gently push
the flat blade of a small screwdriver into one slot at a time and pry upward until
the catch disengages. Carefully swing the thermostat upward and away from the
subbase. (Figure 1)
THERMOSTAT LOCATION
The SMART 1000 should be installed in a location that
represents the ambient space temperature. Do not install
the thermostat in an area where drafts are present, near
the floor, behind doors or on an external wall. Avoid
placing the thermostat in areas where the air movement
is limited, affected by direct sunlight or other areas not
represented by typical of the temperature in the space.
MOUNTING THE SUBBASE
When mounting the SMART 1000 subbase, be aware that drafts
may travel down wall cavities and enter the back of the thermostat
through the control wire hole in the wall. It is important to seal
the hole to prevent any drafts that might affect the internal
temperature sensor.
FIGURE 1
6
INSTALLING THE THERMOSTAT
Pull the control wires through the large opening in the thermostat subbase. Next,
level and mount the subbase on the wall using the supplied anchors and screws.
(Figure 2)
Do not over tighten the mounting screws as the subbase may warp causing
the improper seating of the thermostat connecting pins to the terminal
blocks.
Use a properly sized
screwdriver and back each
screw terminal out (counter
clockwise) before landing each
wire to its dedicated terminal.
Do not over tighten the terminal
screws. Check to ensure that all
wires are landed correctly and
dressed properly to prevent any
shorts. Refer to Typical System
Wiring Diagrams in this manual
for proper wiring.

SETTING THE SYSTEM SWITCHES
The SMART 1000 contains a set of four system switches located on the thermostat
printed circuit board. (Figure 3) The switches are used to match the thermostat
operation and relay outputs with the HVAC system requirements. Refer to the
system switch functions on the next page to properly configure the thermostat.

INSTALLING THE BATTERIES
The SMART 1000 comes with two AA batteries. Even if the thermostat is hardwired,
battery backup is recommended to maintain the real-time clock in the event of a
power failure. All other memory is non-volatile in the event of battery or primary
power loss. Press in on the battery access compartment and slide the drawer
out. Install the two AA batteries matching the + and - orientation. Push the battery
compartment in until it clicks shut. When the batteries are properly installed, the
touchscreen display will light up. (Figure 4)
