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 SC-T32-TS thermostat are as follows.
1. Read and understand this Installation Manual and User 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 thermostat 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
typical of the temperature in the space.
MOUNTING THE SUBBASE
When mounting the thermostat 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

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. FIGURE 2
