Saving to Experience
Since the ECM variable-speed
blower motor uses less electricity
than a conventional blower motor,
not only will you have increased
comfort, but you can also save
money (based on 0.08/kWh
electric cost).
Premiere Oil Furnace
Dependable Craftsmanship
with Maximum Comfort
When you want to experience
exceptional comfort, increased
effi ciency, and quieter operation while still receiving the
handcrafted quality and proven
warranty of ermo Pride’s
traditional oil furnace, select
the Premiere Oil Furnace with
the ECM variable-speed blower
motor. Since the ECM motor
automatically adjusts its speed
for varying heating and cooling
modes your home’s maximum
comfort is achieved.
ECM Blower Motor
1. Annual Savings for heating
your house — average $58
2. Annual Saving for heating and
cooling your house — average $76
3. When using a constant fan that
runs for air fi ltration, your annual
savings can average $480 for just
heating your house or $429 for
heating and cooling your house.
“ is Furnace is much quieter. Heats
rooms that were cool with previous
furnace. So far we have used less kw
of power each month compared to the
previous year.”
Bob Williams, VP of Rossoe Energy
Systems & Oil Company
Some of the ECM benefi ts include:
• quieter start up, greater effi ciency, and more comfortable
operation due to infi nite fan motor speeds
• delivery of comfortable airfl ow in both the heating and
cooling modes. On a call for heat or cooling the blower
motor starts at the slower speed and builds to the correct
running speed
• automatically compensates for restricted ducts or a dirty
air fi lter by increasing the motor speed (routine fi lter
cleaning is still recommended.)
• energy bills will be lower due to quieter effi ciency of the
ECM motor (especially when you run the blower for
long periods of time.)
• reduced fan speeds will run quietly and save energy
when the blower runs constantly as with
air fi ltration, for example.

Additional Features
General
• Eliminates the need for air temp thermostat to control fan cycling by using time instead.
• Selectable blower turn-on and turn-off delays to adjust comfort & efficiency
(turn-on: 30, 60, 120 & 240 sec; turn off: 2, 4, 6 & 8 min)
• ree blower operating choices: HEAT, COOL & FAN for best efficiency for each mode.
• Reduces A/C blower speed 50% on demand to increase dehumidification.
• Cooling blower delays of 10 seconds on, and 45 seconds off to enhance cooling comfort and efficiency.
Cycle Control
• 4 minute minimum A/C off time to reduce Short-Cycle related failures.
• A high limit will cause the blower run at the selected HEAT speed. It will then run for the HEAT turn off
time afterwards in the absence of a HEAT call.
• Blower operation will “time out” before mode is switched between HEAT & COOL to prevent stress related
evaporator failures.
• Burner Cut-Off on high limit
Speed Control
• Selectable air temperature (heat) rise from Return to Supply Plenum (choose from: 63, 69, 75 and 85ºF)
• Selectable CFM rates for matching A/C tonnages. ese CFM selections support from 2.0 to 3.5 tons.
• Maximum CFM’s are limited by the maximum RPM of the ECM motor and the duct static pressure.
Please refer to the manual addendum for guidelines.
Diagnostics
• Control Input LED’s indicate active thermostat input lines.
• Diagnostic LED indicate:
1. Active Operation (turn full on during burner or compressor operation)
2. A HIGH LIMIT condition. (flash on/off at 2 ½ times per second)
