in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or
more of the following measures:
HVAC Wire Harness Templates
Use the wire harness templates below to note your
wiring connections.
During normal operation, the measured ambient
temperature is continuously monitored to ensure it
does not exceed the High Temperature Protection
setpoint if High Temperature Protection is enabled.
Similarly, the measured ambient temperature is
monitored to ensure it does not fall below the Frost
Protection setpoint if the Frost Protection configura-
tion is enabled.

Auto
• Increase the separation between the equipment and
receiver.
Protection Modes
The Frost Protection and High Temperature
Protection modes can be enabled or disabled.
When enabled, their setpoints are configurable, as
described below.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV
technician for help
• Frost Protection (low temperature) can be
enabled or disabled. When enabled, its setpoint
ranges from 5 to 15°C (41 to 59°F). Default
is 5°C (41°F). If Frost Protection is enabled
and the measured ambient temperature is
lower than its Frost Protection limit, then even
when the device is OFF, heating will turn on
automatically, as indicated on the LCD. Heating
will turn off when the ambient temperature
reaches the setpoint + 2°C (4°F).
Industry Canada
This device complies with Industry Canada
licence-exempt RSS standard(s) . Operation is sub-
ject to the following two conditions: (1) this device
may not cause interference, and (2) this device
must accept any interference, including interference
that may cause undesired operation of the device.

Le présent appareil est conforme aux CNR d’In-
dustrie Canada applicables aux appareils radio
exempts de licence. L’exploitation est autorisée
aux deux conditions suivantes : (1) l’appareil ne
doit pas produire de brouillage, et (2) l’appareil doit
accepter tout brouillage radioélectrique subi, même
si le brouillage est susceptible d’en compromettre
le fonctionnement.
The default modes displayed by TH900 Series
thermostats are OFF and Auto. Other available
mode options include OFF/Auto/Heat/Cool, OFF/
Heat Only and OFF/Cool Only. In order to access
these modes, the user must first enable them within
the Installer Setup Setting Mode settings.
• High Temperature Protection can be enabled
or disabled and its setpoint ranges from 25 to
35°C (77 to 95°F). The default is 35°C (95°F).
If High Temperature Protection is enabled and
the measured ambient temperature is higher
than its setpoint limit, then even when the
device is OFF, cooling will turn on automatically
as indicated on the LCD. Cooling will turn OFF
when the ambient temperature decreases to the
High Temperature Protections setpoint minus
2°C (4°F).
With a short press of the MODE button, the ther-
mostat will cycle between OFF > Auto by default
modes. In each of these modes, the contents of the
display change accordingly. Note that Auto, Heat
Only and Cool Only have identifying icons displayed
above (touchscreen version) or to the left of the
temperature (pushbutton version).
WEEE Directive 2012/19/EC
Waste Electrical and Electronic Equipment
Directive
Dispose of this device separately from household
waste at an official collection point. Professional
recycling protects people and the environment
against potential negative effects.
If the low temperature exceeds the display range
of 0°C (32°F), this will be indicated with ‘LO’ on the
LCD.
• In Auto mode, the measured ambient
temperature is compared to the set point.
Temperature control is achieved by setting
the fan speed to automatic and engaging the
heating or cooling valves.

If the high temperature exceeds the display range
50°C (122°F), this will be indicated with ‘HI’ on the
LCD.

This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any
interference received, including interference that
may cause undesired operation.
• When the fan is operating under automatic
control, the applicable fan on/off is chosen
automatically based on the temperature
difference necessary to achieve the air
temperature set point.
If the on-board temperature sensor is not operating
correctly (if it is open or short), ‘Er’ will be displayed
on the LCD.
Note: This equipment has been tested and found to
comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference
• If the user selects the fan to run in low speed
via the fan button, then temperature control is
delegated to the heating control and cooling
control. The fan is no longer modulated until
