2.5.1 Anticipator adjustment (if required)
on thermostat equipped with heat
anticipator adjustment
Some thermostats are equipped with a heat anticipator
that must be adjusted according to the instructions
supplied.
This is to ensure that the heating mode is
comfortable and economical. Generally speaking, on a
single stage thermostat, a reading of the current must be
taken with an ammeter as follows:
1. Move the anticipator to its highest setting, rendering
it ineffective.
2. Remove the wire from the W1 terminal of the
furnace and connect an ammeter between the
terminal and the wire.
3. Call for heat by raising the set point on the
thermostat and allow the furnace to run for 3 to 4
minutes to reach its peak output.
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 Air ducts
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.
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
The supply air must be adjusted based on heating/air
conditioning output and the static pressure of the duct
system. For the desired airflow, refer to Table 1, as well
as Table 4 and Table 5 for the airflow based on static
pressure.
For the adjustment of the airflow on heating mode, to
obtain the temperature rise described in the technical
specification table Table 2 and Table 3), the orange wire
must be positioned on the terminal corresponding to the
LOW, MED-LOW, MED-HIGH or HIGH blower speed.
For the adjustment of the airflow on air-cooling mode,
to obtain a sufficient airflow (350 to 450 CFM per
Ton), the blue wire must be positioned on the terminal
corresponding to the LOW, MED-LOW, MED-HIGH or
HIGH blower speed.
Blower speeds are adjusted in factory for 0.5 inch W.C.
