2.4- ELECTRICAL SYSTEM
The S
UPREME
furnace is completely pre-wired and all field wiring
must be connected to the terminal blocks on the unit. It requires
a 120/240 - 208 volt.
WARNING
R
ISK OF FIRE
The conductor sizing must conform to the last edition of the
local or national codes.
Failure to follow this rule can result in death, bodily injury
and/or property damage.
Power supply to the unit can be done using copper or aluminum
wires. The wire size must be decided in accordance to the unit
power consumption, the over current protection type and
capacity, the wire type and length, and the environment where
the unit is installed. If an aluminum wire is used, other
precautions must be taken to insure the conformity of the
installation. In all cases, all the factors affecting the wire gauge
must be considered and the installation codes followed.
The exterior of the unit must have an uninterrupted ground to
minimize the risk of bodily harm. A ground terminal is supplied
with the control box for that purpose. A connector is supplied on
the ground terminal to ground an added accessory.
In the event that wires inside the unit require replacement, these
must be copper wires only with same temperature rating and
sizes as originals.
2.4.1- Conversion from two to one supply wires for model
over 27kW
WARNING
When using one terminal block on models of 27kW and
higher, the installation must be performed with copper wire
ONLY in order to comply with the Canadian electrical code.
The usage of an aluminum or copper wire is acceptable on
models 25kW and lower.
Move all wires from the two pole terminal to the three pole
terminal following the corresponding colors as shown in Figure
4.
The breaker and the supply conductors must be sized by adding
the ampacities of the two terminals indicated on the nameplate.
Refer to the electrical diagram Figure 11.
Figure 4 : Conversion from two to one supply wires
Before
After
2.5- INSTALLATION OF THE THERMOSTAT
2.5.1- Communicating thermostat with Alizé system
The thermostat must be connected to terminals 1, 2, R and C of
the furnace. The interface board must be installed as specified
in the supplied manual and connected with the RJ11 wire also
supplied with the interface board.
Figure 5 : Communicating thermostat connection
2.5.2- Modulating thermostat
The thermostat must be connected to V/W2, C, R, G terminals
and optionally to Y1, Y2, O and DH terminals if the there are
options of cooling or heat pump.
Figure 6 : Modulating thermostat connection
2.5.3- Ducts and filters
The ducts must be sized to accommodate the specified airflow
and the available static pressure. Refer to the applicable local
and/or national installation codes.
Insulate the ducts that lead through non-heated areas. Use
flexible supply and return air connectors to avoid the
transmission of vibration. To make the unit run even quieter, the
installer should:
a. Use two elbows between each outlet and the supply and
return air plenum;
b. Cover the vertical sections of the supply and return air duct
with soundproofing material;
c.
Use baffles in short radius elbows;
d. Use flexible hangers to suspend the ducts.
The S
UPREME
furnace is equipped with a filter frame for the
blower compartment. It must be installed on the outside of one
of the three sides or the bottom of the furnace. Once the location
6
of the installation has been determined, use the four square
knockouts for ease of cutting the opening.
A heat pump or an air conditioner can be added to this furnace,
in either the supply or return air duct. Carefully follow the
instructions provided with these appliances to ensure proper
installation and hook-up to the electric furnace. Refrigerant and
drainage pipes must in no way hinder access to the furnace
panels.
2.6- INSTALLATION OF ACCESSORIES
WARNING
E
LECTRICAL SHOCK HAZARD
Turn OFF electrical power at the fuse box or service panel
before making any electrical connection and ensure that a
proper ground connection is made before connecting line
voltage.
Failure to do so can result in death or bodily injury.
2.6.1- Humidifier and humidistat connection
Fan Control Board terminals HUM1 (directly connected
internally to C on terminal block) and HUM2 (directly connected
internally to G on terminal block) are provided for direct
connections to the low-voltage control of a humidifier through a
standard humidistat (refer to Figure 7). These terminals are
energized with 24 VAC when G thermostat signal is present.
Figure 7 : Standard humidistat connections
2.6.2- Dehumidify capability with standard humidistat
connection
Latent capacities for systems using this unit are better than
average systems. If increased latent capacity is an application
requirement, the field wiring terminal block provides a
connection terminal (DH) for use of a standard humidistat. The
furnace control will detect the humidistat contact opening on
increasing humidity and reduce its airflow to approximately 80%
of nominal cooling mode airflow. This reduction will increase the
system latent capacity until the humidity falls to a level which
causes the humidistat contact to close its contacts.
2.6.3- Use of a heat pump
When using a heat pump, a thermostat with dual fuel option or
a fossil fuel kit is required that prevents the operation of the
electric elements and the heat pump at the same time. Refer to
the instructions provided with the thermostat or the “Fossil Fuel”
kit for the proper wiring of the furnace and the heat pump.
The simultaneous operation of the electric elements and the
heat pump will cause overheating of either unit. The safety
controls of the appliances will shut down the elements or heat
pump, since they are not designed to function in this fashion.
The only acceptable option to have the furnace and a heat pump
to run simultaneously is to use the Modulating S
UPREME
in
combination with the A
LIZÉ
outdoor unit combined with the
interface board. This operation mode requires the coil to be
installed in the return of the furnace. Refer to section 3.2.5-
AUTO BACKUP Menu for further information.
2.6.4- Placement of interface board
Dettson’s modulating heat pump
unit is a great addition to the
Modulating S
UPREME
. In order to install the interface board to the
S
UPREME
using the included plastic standoffs, consult Figure 8
placement of interface board. Please refer to the A
LIZÉ
manual
for connection diagrams.

4.3.1- Supply air temperature rise test
1. Operate the unit at maximum power for at least 10 minutes;
2. Measure the air temperature in the return air plenum;
3. Measure the air temperature in the largest trunk coming off
the supply air plenum, just outside the range of radiant heat
from the heat exchanger. 0.3 m (12”) from the plenum of
the main take-off is usually sufficient;
4. Calculate the temperature rise by subtracting the return air
temperature from the supply air temperature.
10
If the temperature rise exceeds the temperature specified
(
5˚F
/2.8°C) in Table 2, adjust the fan speed. If the excessive
temperature rise cannot be reduced by increasing fan speed,
investigate for ductwork obstructions or dirty and improper air
filter.
CAUTION
It is important to check the airflow and to ascertain that the
unit does not operate above the temperatures specified in
the Technical Specifications (Table 2). This is particularly
important if a cooling coil or a heat pump has been installed
in the system.
Hi-Limit thermal protectors should never need to engage
during the normal functioning of the appliance. They are
strictly designed to engage during the improper functioning
of the blower or when the filter was improperly maintained.
4.3.2- High limit verification
After operating the furnace for at least 15 minutes, restrict the
return air supply by blocking the filters or the return air register
and allow the furnace to shut off on High Limit. The electric
heaters must deactivate themselves before the warm air
temperature exceeds 200˚F
(93°C).
Remove the obstruction and the elements should restart after a
few minutes.
5- MAINTENANCE
WARNING
E
LECTRICAL SHOCK HAZARD
.
Turn OFF power to the furnace before any disassembly or
servicing.
Failure to do so can result in death, bodily injury and/or
property damage.
Preventive maintenance is the best way to avoid unnecessary
expense and inconvenience. Have your heating system
inspected by a qualified service technician at regular intervals.
Do not attempt to repair the furnace or its controls. Call a
qualified service technician.
Before calling for repair service, check the following points:
1. Check fuses or the circuit breakers;
2. Check if the 15 A circuit breaker on the furnace is
disengaged;
3. Set the thermostat higher than room temperature. If the unit
does not start up, cut the power and call a qualified service
technician.
When calling for service or ordering a replacement part, specify
the model and serial number of your appliance.
5.1- AIR FILTER
The filter supplied with the unit should be replaced twice a year.
The presence of animal hair, dust, etc. may necessitate more
frequent changes. Dirty filters have an adverse effect on the
performance of the central heating system.
5.2- MOTOR LUBRICATION
Do not lubricate the blower motor, since it is permanently
lubricated.
