2 Heat/2
Cool
Auto−changeover
Controls humidity during
cooling operation.
Easy−to−use, menu
driven thermostat with a back−lit, dot−matrix LCD
screen.
Remote outdoor sensor (furnished) allows the
thermostat to display outdoor temperature and adjust
indoor dewpoint temperature for precision humidity
control in cooling mode.
See the SignatureStat Engineering Handbook bulletin in
the Controls section for more information.
BLOWER
Variable Speed Direct Drive Blower
Each blower assembly statically and dynamically
balanced.
Change in blower speed is easily accomplished by
simple DIP switch change on Integrated Furnace Two
Stage / Variable Speed Blower Control.
See Blower Performance tables.
Blower assembly easily removed for servicing
Variable Speed Blower Motor
Variable speed motor maintains specified air volume
from 0 though 200 Pa static range.
Motor is controlled by Integrated Furnace Two Stage /
Variable Speed Blower Control.
Motor is resiliently mounted.
FILTER (NOT FURNISHED)
Filter and provisions for external mounting must be field
provided.
CABINET
Low−profile, narrow width cabinet allows easy
installation in up−flow, down−flow or horizontal
applications.
Heavy−gauge, cold rolled steel construction.
Pre−painted cabinet finish.
Flanges provided on supply air opening for ease of
plenum connection or alignment with indoor coil.
Fully insulated cabinet with foil faced insulation on sides
and back of heating compartment and mat faced
insulation in blower compartment.
Tool−less latches on blower and burner doors assure
positive lock.
Complete service access.
Safety interlock switch automatically shuts off power to
unit when blower compartment access door is removed.
Gas piping inlets are provided in both sides of cabinet.
Return Air Entry:
For bottom/end return−air entry for up−flow/horizontal
applications, remove furnished bottom seal panel from
cabinet.
For side return−air entry (up−flow applications only),
corners are marked on either side of cabinet for return
air cut−outs.
On furnaces with side return air and condensate trap on
the same side of the cabinet, a field fabricated transition
is required when using an IAQ (indoor air quality)
product higher than 360 mm installed next to the unit
and serviced from the front. IAQ products higher than
508 mm require a field fabricated transition. See
dimension drawings.
NOTE − 60C and 60D size units that require air
volumes over 850 L/s must have one of the
following:
1. Single side return air with transition, to accommodate
508 x 635 x 25 mm cleanable air filter, required to
maintain proper air velocity.
2. Bottom return air.
3. Return air from both sides.
4. Bottom and
one side return air.
See Blower Performance Tables for additional
information.
Coil Match−up
All furnaces exactly match C33 and CX34 cased up−flow
indoor coils and CH33 horizontal indoor coils with same
letter designation in model number. No adaptor
required. Engaging holes furnished on cabinet for
alignment.
C33 uncased coils match furnaces without any
overhang but require an optional adaptor base or field
fabricated transition to match furnace opening. See C33
coil bulletin for additional information.
All furnaces exactly match CR33 cased, down−flow
indoor coils with adaptor rails, furnished with coil.
OPTIONS
Condensate Trap Alternate Location Kit
Allows condensate drain to be installed on the opposite
side of the furnace from the exhaust venting (up−flow
applications only).
Down−Flow Combustible Floor Base
Required for heating only units installed on combustible
floors.
Not required in add-on cooling applications.
See Dimension Drawing.
