OFF-HEAT-AUTO-COOL-EMERG system switch, OFF-AUTO
blower switch, and indicating display shall be provided. The
thermostat shall display in °F or °C. The thermostat shall provide
real time energy consumption data of the unit.
Communicating Color Touchscreen Thermostat
(field-installed)
A color touchscreen communicating auto-changeover electronic
digital thermostat shall be provided. The thermostat shall
offer variable speed heating and cooling staging with precise
temperature control. An OFF-HEAT-AUTO-COOL-EMERG system
switch, OFF-AUTO blower switch, and indicating display shall be
provided. The thermostat shall display in °F or °C. The thermostat
shall provide real time and historical energy consumption data of
the unit.
Electronic Air Cleaner (field-installed)
A 1 in. [25 mm] electronic air cleaner, cleanable 97% efficiency at
0.3 microns and larger, shall be provided in lieu of the standard
throwaway filter. The initial pressure drop across the filter shall not
exceed 0.2 in. w.g. at 300 fpm force velocity.
Electrostatic Air Cleaner (field-installed)
A 1 in. [25 mm] electrostatic air cleaner, cleanable 90% efficiency,
shall be provided in lieu of the standard throwaway filter. The initial
pressure drop across the filter shall not exceed 0.15 in. w.g. at 300
fpm force velocity.
External Sump Alarm Sensors for Aurora Controls
The sensor can be added to any Aurora Advanced Control System
(including both ABC and AXB) to monitor a sump pump. The sen-
sor can be connected to the Aurora Home Automation inputs (HA-1
or HA-2) of the AXB board. These will each display an E23 and
E24 code respectively when the alarm is active and when Sym-
phony/AWL is installed will also produce text/e-mail notifications.
• This sensor provides a relay closure that can be used to trip a
fault when moisture is present. This can be used as a primary
sump alarm or simply a wet basement or signal a blown
washing machine hose.

AlpinePure MERV 13 Filter (field installed)
A 2 in. [50 mm] thick MERV 13 filter shall be provided in lieu of the
standard filter and fits the factory filter rack. The filter maintains
MERV 13 rating in full ASHRAE 52.2 independent testing as
required for LEED
LEED rating system.
AlpinePure HEPA Filter (field installed)
For the ultimate in air filtration, the AlpinePure Series HEPA filter
captures 99.97% of all particles down to 0.30 microns in size.
AlpinePure Drain Pan Treatment (field installed)
Provides dependable, sustained time-release protection from slime
build-up and foul smelling odors in the drain pan. Also adds a light,
pleasant scent to the air.
Earth Loop Flow Center (field-installed)
A self-contained module shall provide all liquid flow, fill and
connection requirements for ground source closed loop systems
up to 20 gpm. The pumps shall be wired to a power block located
in the nearest unit. The heat pump units shall contain low voltage
pump linking control so that two units may share one flow center.
Auxiliary Heater (field-installed)
An electric resistance heater shall provide supplemental and/or
emergency heating capability. Vertical units shall have the control
panel and resistance heater coil assembly mounted internally. For
horizontal units, the control panel shall be mounted internally while
the resistance heater coil assembly shall be mounted externally. A
low voltage plug shall be provided in each unit for quick auxiliary
heat connection. The heater shall operate in sequenced stages
as controlled by the unit's microprocessor. The heater shall feed
line voltage power to the unit blower and transformer to provide
emergency heat capability in the event of an open compressor
circuit breaker.
