FORM100.50-EG12 (918)
Wall-Mount Zone Sensor –
A 10 kOhm thermister type III NTC zone sensor for wall
mounting. This zone sensor is for sensing temperature only, and does not include any
setpoint adjustment features.
COMMUNICATIONS
BACnet
®
MS/TP (RS-485) Communications –
This communication option is standard on
every Series 100 unit. Communications to the unit are through a twisted pair, and the wire
terminations are on the primary unit control board. See supplemental information for the
available control points and PICS/Bibbs statements of conformity.
Modbus
™
RTU Communications –
This communication option is standard on every Se-
ries 100 unit and can be used in lieu of the BACnet communications (only one can be
used at a time). See supplemental information for the available control points.
FILTER OPTIONS
Filter Options –
Two-inch throwaway, cleanable, carbon coated MERV 8 or pleated
MERV 8 filters in an angled rack are available. For higher filtration requirements, optional
rigid filter racks are available with 12-inch 65% (MERV 11) or 95% (MERV 14) efficient
rigid filters. Two-inch MERV 8 pre-filters are included with rigid filter options. The rigid filter
rack option is available without filter media where field-supplied filters are required.
OUTSIDE AIR DAMPER OPTIONS
Manual Damper
– This option includes a manually adjustable outside air damper. It is
manually adjustable at the unit by setting a mechanical stop between 0–100%.
Two-Position –
This outside air damper option is controlled to a two positions, opened
and closed. Determination of the damper position is based on the occupancy schedule. In
the occupied mode, the outside air damper is positioned to the manually configured point
(set by mechanical stop). In the unoccupied mode, the damper is fully closed.
Modulating Economizer –
This option includes modulating outdoor air and return air
dampers that are software interlocked (YPAL070–105 software interlock) and positioned
by fully modulating, solid state damper actuators. Control of the damper is via a standard
ambient outdoor air dry bulb sensor, or optional single or comparative enthalpy controls.
Airflow Measurement –
Optional outside airflow measurement is available on units
equipped with a Modulating Economizer.
CO
2
Sensors –
Optional carbon dioxide sensors for occupied space that operate demand
ventilation control opening outside air dampers to ventilate building. The CO
2
sensors can
operate in a single or comparative control scheme.
Rain Hoods on Outside Air Intakes
– For all options with outside air intake openings,
rain hoods are provided as standard to keep moisture from entering the equipment. The
rain hoods are an integral part of the unit and are rotated into place at the jobsite.
RELIEF SYSTEM
Barometric Relief –
This option does not include an exhaust or return fan, but rather
uses barometric relief dampers to exhaust air from the building. The dampers will open
relative to the building pressure. The opening pressure is adjustable via a spring tension
adjustment.
