Product Description
The TH900 Series thermostats are optimized for
ofce building, hotel and residential terminal HVAC
control.
The TH900 Series is ideal for PTAC, Fan Coil, Heat
Pump and Gas/Oil Furnace applications.
These models are available in two housing nishes:
optimum (black glass display with capacitive
buttons on a black or white base) or medium (white
glass display with mechanical buttons on a white
base).
The TH900 Series is a wall surface mount device
that is easy to operate. These thermostats feature
microprocessor-based controls and large LCD
screens which display operation status (cooling,
heating and auto), fan speed, room temperature
and set-point.

Installation
Location
Select a location about 1.5m (5ft.) above the oor
with good air circulation at average temperature.
Indoor use only. Do not mount thermostat where it
may be affected by:
• Drafts or dead spots behind doors or in corners
• Hot or cold air from ducts
• Radiant heat from sun or appliances.
• Concealed pipes or chimneys
• Unheated (un-cooled) areas behind the
thermostat
• If Zigbee equipped, do not install near other RF
sources/ transmitters
• When the thermostat is equipped with PIR,
consider view angle, range characteristics, and
mounting position for proper coverage
Mounting
The HVAC thermostat is typically mounted on a
standard double-gang (4 x 4) junction box. The in-
stallation kit provides a Smart Wall Mounting Plate.
If mounted on a single-gang box, use the two cen-
tral holes of the Smart Wall Mounting Plate.
To mount the HVAC thermostat, complete the
following steps:
1. Position the Smart Wall Mounting Plate as
shown in Figure 1.
2. Ensure the Smart Mounting Plates are oriented
to follow the marking that says “This side up”.
Snap them together, ensuring all 4 corner snap
hooks are attached, then attach them to the
junction box using the supplied screws.
3. Use wire nuts to connect the Power/HVAC
and other low voltage signal wiring harness
to the power and heat pump/valve/fan control
signal wires within the electrical box. See
the pre-dened commissioning document for
application-specic wire connections.
4. To connect the unit to the input power and the
relays to the loads, plug the pre-wired power/
HVAC and other signals harness connector into
the female receptacle at the back of the unit
(H1/H2/H3).
5. Hook the tabs at the top rear of the unit housing
into the matching depressions at the top of the
Smart Mounting Plate and rotate the bottom of
the housing toward the wall until it snaps into
place.
6. Secure the housing to the Smart Mounting
Plate with the two small captive screws at the
bottom of the housing.
7. Apply power to the unit by closing the
applicable supply breaker. After connecting
power, OFF mode (factory default setting) will
appear on the LCD display.

Wiring Diagrams
Note: Prior to beginning an installation, use the
HVAC Wire Harness Templates at the end of this
document to identify the wires/signals coming out
of the 4x4 box and to determine which wires are
connected to which wires on the thermostat. These
templates provide a quick and easy ‘cheat sheet’ to
capture property-specic wiring requirements.
If you have technical questions, please contact the
Schneider Electric Customer Care Center in your
country (see schneider-electric.com/contact).
