certied electrician, according to the electrical and building codes
effective in your region.
The following instructions must be adhered to in order to avoid personal injuries or property damages, serious injuries and potentially fatal electric shocks.
Make sure that all screws and electrical terminal connections are tightly secured before operating the unit in case they would have loosened during
transportation.
Protect the heating unit with the appropriate circuit breaker or fuse, in accordance with the nameplate.
Make sure the line voltage (volt) is consistent with that indicated on the unit’s nameplate.
This unit must be grounded.
Switch off the power at the circuit breaker/fuse before installing, repairing and cleaning the unit.
Make sure the unit is appropriate for the intended use (if needed, refer to the product catalog or a representative).
Respect distances and positions indicated in the installation section.
void.
This unit must not come into contact with a water source and must be protected from splashes (e.g. a wet mop). Do not use it if any part has been immersed.
Moreover, do not turn it on or off when standing in water or if your hands are wet.
When cutting a piece of steel for the installation of the return duct, do not damage electrical wiring of the unit.
Because this unit is hot when in use, it may pose risks even in normal operation. Therefore, be careful and responsible when using it. To avoid burns, do
not let bare skin touch hot surfaces. Let the unit cool down for a few minutes before handling it (it stays warm for some time after shut-down).
Some areas are dustier than others. Thus, it is the user’s responsibility to evaluate if the lter must be changed
Thermal protection activation indicates that the unit has been subjected to abnormal operating conditions. If the thermal protection remains activated or
damaged. (Refer to the limited warranty).
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
WARNING
Note:
instances, the instruction manual may not entirely match all the functions of the actual product. Therefore, the actual product and packaging, as well as the name
and illustration, may differ from the manual.

OPERATION
HEATING DEMAND
ONE-STAGE THERMOSTAT
W1- The thermostat closes the R-W1 circuit, which activates 100%
of the heating sequence. The blower starts up at medium speed and
the furnace elements are activated one by one to reach the adjustable
temperature limit set on the potentiometer of the furnace control card.
If there is still a W1 heating demand after 30 minutes, the heating
sequence continues as per the W2 sequence.
Or W2- If there is still a W1 heating demand after 30 minutes, the
sequence continues as follows: the blower switches to the medium
speed and all the furnace elements are activated one by one (100%
heating). The plenum temperature is still limited by the potentiometer
of the control card.
TWO-STAGE THERMOSTAT
The control card of the furnace auto-detects the two stages of the
thermostat.
W1-
stage of the heating sequence (±50% heating). The blower starts up
at low speed and the furnace elements are activated one by one to
reach the adjustable temperature limit set by the potentiometer on the
furnace control card.
If there is still a W1 heating demand after 30 minutes, the heating
sequence continues as per the W2 sequence.
And/Or W2- If the thermostat closes the R-W2 circuit, the sequence
continues as follows: the blower switches to the medium speed and all
the furnace elements are activated one by one (100% heating). The
plenum temperature is still limited by the potentiometer of the control
card.

CONTINUOUS HEATING
The continuous heating option allows one or two heating elements to operate continuously. The user can select the minimum (one element) or
mode is useful from the beginning to the end of the heating season since it reduces temperature variations into the house. If the minimum or
maximum continuous heating option is activated by the user, the furnace will deactivate it when the heating season ends (more than two hours
without any heating demand). Moreover, it will reactivate it when a new heating season begins. Note that the pilot light indicating the heating
option will blink if the furnace deactivates this option because the heating season is over. This indicates that the continuous heating will be
activated again at the start of the next heating season.

The heat pump can operate all year and allows the user to make energy savings due to the plenum temperature regulation function (exclusive to
Stelpro). This function ensures a constant temperature into the plenum and the ducts. When it is cold, the heating capacity of the heat pump is
reduced. For type “B” installation, the furnace will compensate for the capacity loss of the heat pump. Even when the defrosting mode of the heat
pump is activated and begins to cool the air, the furnace will quickly increase the heating capacity in order to offset the cooling effect caused by the
defrosting mode of the heat pump.
