4) Once the current has stabilized, a reading should be
taken and the anticipator adjusted to that value. If
longer heating cycles are desired, the anticipator can
be set to a higher value
2.5.2.
Ducts and filters
The ducts must be sized such a way as 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:
1) Use two elbows between each outlet and the supply
and return air plenum;
2) Cover the vertical sections of the supply and return air
duct with soundproofing material;
3) Use baffles in short radius elbows;
4) Use flexible hangers to suspend the ducts.
The
SUPREME
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 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 SUPPLY AIR ADJUSTMENTS AND
OTHER BLOWER SETTINGS
Fan Control Board taps are used by the installer to configure a
system. The ECM motor uses the selected taps to modify its
operation to a pre-programmed table of airflows (Refer to Table
3 and Table 4). Airflows are based on system size or mode of
operation and those airflows are modified in response to
thermostat inputs.
FEM electric furnace must be configured to operate properly
with system components with which it is installed. To
successfully configure a basic system (see information printed
on circuit board label located next to select pins), move the 6
select wires to the pins which match the components used.
(Refer to Figure 4 below)

2.6.1.
HEAT KW/CFM adjustment
Installer must verify (factory set) the electric heat airflow
adjustment required for kW size heater installed.
The select pins are marked 23, 20, 18, 15 (for ½ HP ECM motor
unit) and 27, 23, 20, 18 (for 1.0 HP ECM motor unit). Refer to
the unit wiring diagram and select the pin for the heater size
being used (Refer to Figures 4 and 9).
The airflow must be large enough for safe and continuous
operation. (Refer to Table 3 and 4 for airflow delivery CFM).
2.6.2.
AC/HP size
Select System Size Installed
The factory setting for air conditioner or heat pump size is the
largest outdoor unit that can be used with the furnace. Installer
needs to select air conditioner or heat pump size to ensure that
airflow delivered falls within proper range for the size unit
installed.
The select pins are marked 036, 030, 024, 018 for furnace
equipped with ½ HP ECM motor and 060, 048, 042, 036 for
furnace equipped with 1.0 HP ECM motor. Refer to the unit
wiring diagram and select the pin for the outdoor unit size being
used (Refer to Figures 4 and 9).
