DESCRIPTION
The TH450 thermostat is designed to control an electric heating system such as
a baseboard heater, a radiant ceiling, a convector, or a fan-forced convector.
This thermostat cannot be used with:
- a resistive load under 1.25 A
- a resistive load over 16.7 A
- a system is driven by a contractor or a relay (inductive load)
- a central heating system
SUPPLIED PARTS
- One (1) thermostat
- Two (2) 6-32 mounting screws
- Two (2) solderless connectors
INSTALLATION
The installation must be carried out by an electrician and must comply with local electrical codes.
WARNING
CUT POWER TO THE HEATING SYSTEM AT THE MAIN ELECTRICAL PANEL TO AVOID ANY RISK
OF ELECTRICAL SHOCK.
Loosen the screw and remove the faceplate of the thermostat from its
wallplate.
NOTE: The screw remains captive on the wallplate.
Make the connections using solderless connectors for copper wires. The thermostat wires are non-polarized; this means either wire can be connected to either terminal.
WARNING
This thermostat has tinned copper wires for line and load connections. Special
CO/ALR solderless connectors must be used when connecting with aluminum
conductors.
Install the wall plate to the electrical box.
Set the configuration switches on the back of the thermostat’s faceplate (see section 3).
Install the faceplate of the thermostat back on the wallplate and tighten the
screw.
NOTE : If there is a protective film or sticker on the thermostat’s
screen, peel it off.
Apply power to the thermostat. Verify the installation by checking that the
heater can be turned On and Off by raising and lowering the setpoint using the
∧ and ∨ buttons.
NOTE: Keep the air vents of the thermostat clean and unobstructed at all
times.

3| Temperature display format| °C| °F
a. The settings are locked. The temperature adjustment buttons only allow you
to view the temperature setpoint.
b. Select short cycles (15 seconds) in most cases as it provides better
temperature control. However, you must select long cycles (5 minutes) if you
have a fan-forced heater.

TEMPERATURE DISPLAY AND SETTING
- The thermostat normally displays the actual temperature. To view the setpoint temperature, press once on either temperature adjustment button. The setpoint temperature will appear for 5 seconds. The icon
⇒appears when the setpoint is displayed. - To change the setpoint temperature, press the appropriate button until the desired value is displayed.

POWER OUTAGE
During a power outage, LP (Low Power) appears for the first minute. Then the screen becomes blank. The settings are stored in memory. After initial installation, the product must be connected to power for a minimum of two hours to enable the power outage feature. However, if the power failure exceeds 4 hours, the thermostat’s clock must be re-adjusted and, if you are using the automatic Daylight Savings Time changeover function, it must be re- enabled. When power returns, the thermostat will return to the mode of operation active prior to the power failure.
TROUBLESHOOTING
| PROBLEM | SOLUTIONS |
|---|---|
| The thermostat’s housing is hot. | This is normal. When the thermostat is |
running at full capacity, its housing can reach 40 °C (104 °F).
LO is displayed.| The measured temperature is below the display range. Heating
is activated.
HI is displayed.| The measured temperature is above the display range.
Wrong temperature is displayed.| Rectify if any of the following conditions
apply:
•The thermostat is exposed to air draft.
•The sticker on the thermostat’s
screen has not been removed.
•The thermostat is located near or above a heat source such as a light dimmer.
Display disappears and reappears after a few minutes.| The thermal protection
device on the heater has temporarily opened. This can happen if the heater is
obstructed by furniture or curtain and has overheated, or if the heater’s
thermal protection device is too sensitive.
El or E2 is displayed| The thermostat performance is
reduced due to a sensor error. Please contact technical support for more
information.
