•
Downflow Economizer
-
(With barometric relief)
- The
economizer is provided with a single enthalpy input. The
economizer is 2% low leakage type. The economizer has
spring return, fully modulating damper actuators and is
capable of introducing up to 100% outdoor air. As the
outdoor air intake dampers open, the return air dampers
close. The changeover from mechanical refrigeration to
economizer operation is regulated by the standard single
enthalpy input. There is an optional input dual dry bulb
available. To meet regulated air standards, the economizer
control accepts an optional CO
2
input for
demand
ventilation. With single enthalpy input, the economizer
control monitors outdoor air. The dual enthalpy kit provides a
second input used to monitor the return air. With a dual input
kit installed, the economizer control compares the values of
the two enthalpy or temperature inputs and positions the
dampers to provide the maximum efficiency possible.
•
Horizontal Economizer
-
(Without barometric relief)
-
All features of the downflow economizer exist except you
must order the duct mount barometric relief separately.
You must order a 1EH0408 if you are installing a
power exhaust. You can order a 1RD0411 Barometric
Relief for horizontal flow economizer.
•
Slab Economizer for Energy Recovery Ventilator
-
(Without barometric relief or Fresh Air Hood)
- The
economizer is provided with a single enthalpy input. The
economizer is 2% low leakage type. The economizer has
spring return, fully modulating damper actuators and is
capable of introducing up to 100% outdoor air. As the
outdoor air intake dampers open, the return air dampers
close. The changeover from mechanical refrigeration to
economizer operation is regulated by the standard single
enthalpy input. There is an optional input dual dry bulb
available. To meet regulated air standards, the economizer
control accepts an optional CO
2
input for

monitors outdoor air. The dual enthalpy kit provides a
second input used to monitor the return air. With a dual input
kit installed, the economizer control compares the values of
the two enthalpy or temperature inputs and positions the
dampers to provide the maximum efficiency possible.
You can order 1EH0409 Barometric Relief/FA Hood for
field installations without an ERV.
•
Dual Enthalpy Control, Accessory
- This kit contains
the required components to convert a single enthalpy
economizer to dual enthalpy.
•
Barometric Relief Damper
- Zero to 100% capacity
barometric relief dampers for use with horizontal flow, or
field installed slab economizers.
•
Power Exhaust
- This accessory installs in the unit with a
down flow economizer. Power exhaust plugs into the
connector in the unit bulkhead.
You must purchase
1EH0408 barometric relief when applying to a
horizontal flow application.
•
Manual Outdoor Air Damper
- Like the motorized outdoor
air damper, each manual outdoor air damper includes a
slide-in damper assembly with an outdoor air hood and
filters. Customers have a choice of dampers with ranges of
0% to 100% or 0% to 35% outdoor air entry.
•
Motorized Outdoor Air Damper
- The motorized outdoor
air damper includes a slide-in/plug-in damper assembly with
an outdoor air hood and filters. The outdoor air dampers
open to the preset position when the indoor fan motor is
energized. The damper has a range of 0% to 100% outdoor
air entry. Factory installed option or field installed accessory.
•
Smoke Detectors
- The smoke detectors stop operation
of the unit by interrupting power to the control board if
smoke is detected within the air compartment.
•
CO
2
Sensor
- Senses CO
2
levels and automatically
overrides the economizer when levels rise above the
preset limits.
•
Dirty Filter Switch
- This kit includes a differential
pressure switch that energizes the fault light on the unit
thermostat, indicating that there is an abnormally high
pressure drop across the filters.
•
Coil Guard -
Field installed decorative wire coil guard.
•
Hail Guard
- This kit includes a sloped hood which installs
over the outside condenser coil and prevents damage to
the coil fins from hail strikes. Field installed accessory only.
•
Electric Heaters
- The electric heaters range from 9 kW
to 54kW and are available in all the voltage options of the
base units. All heaters are dual staged. All units include
an adapter panel for easy installation of the electric
heaters. Necessary hardware and connectors are
included with the heaters. All heaters are intended for
single point power supply.
• Low Limit / Compressor Lockout Kit
•
Compressor Lockout (CLO):
To prevent mechanical
(compressorized) operation of the unit during cold
outdoor conditions where there is a risk of returning
liquid refrigerant back to the compressors.
•
Low Limit Control (LLC):
To prevent the supply air
from dropping below a specified setpoint by utilizing the
units first stage heating means when there is a demand
for cooling during cold outside conditions.
•
Metal Frame Filter Kit -
Metal frame with polyester filter
medium.
•
Permanent Filters
- Permanent filters are available.
•
Roof Curbs
- The roof curbs have insulated decks and are
shipped disassembled The roof curbs are available in 8” and
14” heights. For applications with security concerns, burglar
bars are available for the duct openings of the roof curbs.
•
Roof Curb Transition -
Single Piece Adapter (10” High) -
Roof curbs for transitioning from Sunline™ units to
Predator
®
units. Fits 7.5 to 12.5 Sunline™
roof curbs only.
•
Burglar Bars
- Mount in the supply and return openings
to prevent entry into the duct work.
•
Thermostat
- The units are designed to operate with 24-
volt electronic and electro-mechanical thermostats. All
units (with or without an economizer) operate with two-
stage heat/two-stage cool or two-stage cooling only
thermostats, depending upon unit configuration.
