Control Arrangements; Installation; Step 1 - Install Volume Control Box - Carrier 35E Installation And Start-Up Instructions Manual

CONTROL ARRANGEMENTS

The 35E single-duct unit is offered with a wide variety of
factory-mounted controls that regulate the volume of air deliv-
ery from the unit and respond to cooling and heating load re-
quirements of the conditioned space. Stand-alone controls will
fulfill the thermal requirements of a given control space. These
devices are available in both pneumatic and electronic arrange-
ments. Carrier Comfort Network
Open DDC (Direct Digital Controls) controllers are communi-
cating controls which are integrated with the building system.
A number of DDC control packages by others are available for
consignment mounting, as indicated.
Control offerings are:
• 35EA (Analog Control)
• 35EC (Carrier Comfort Network
Volume [VAV] Electronic Control)
• 35ED (BACnet* VAV Electronic Controls)
• 35EN (No Control or direct digital controls [DDC] by
Others)
• 35EP (Pneumatic Control)
• 35EV (CCN Variable Volume and Temperature [VVT]
Electronic Control)
• 35EB (BACnet VVT Electronic Controls)
Each control approach offers a variety of operating func-
tions; a control package number identifies combinations of
control functions. The following listings contain the basic func-
tion arrangements for each control offering. Because of the
variety of functions available, circuit diagrams, operating
sequences, and function descriptions are contained in separate
Application Data publications. Refer to the specific control
publication for details.
VAV Control Arrangements —
nished with factory-installed PICs for integration into either the
Carrier Comfort Network (CCN) or Carrier i-Vu Open Digital
Control Systems. Room temperature sensors are not included.
VVT Control Arrangement —
nished with factory-installed PICs for integration into either the
Carrier Comfort Network (CCN) or Carrier i-Vu Open Digital
Control Systems. Room temperature sensors are not included.
Analog Electronic Control Arrangement —
Pressure independent control packages are available without
supplemental heat, with on/off hot water or electric heat, pro-
portional hot water heat, or with cooling/heating automatic
changeover control.
All analog control arrangements include a standard linear
inlet flow sensor, 24-v transformer (optional), control enclo-
sure and wall thermostat to match the control type.
2100: Heating control
2101: Cooling control
2102: Cooling with on/off electric heat control
2103: Cooling with on/off hot water heat control
2104: Cooling/heating automatic changeover control
2105: Cooling with proportional hot water heat control
2110: Cooling with proportional (SSR) electric heat
2111: Cooling with electric heat (up to 3 Stages) and automatic
changeover
2113: Cooling with proportional (SSR) electric heat and auto-
matic changeover
Pneumatic Control Arrangement —
packages are pressure independent (unless otherwise noted)
and available with or without hot water heat, dual maximum
airflow, heating and cooling maximum airflow and dual mini-
mum airflow. All control arrangements include a standard
linear inlet flow sensor.

PNEUMATIC CONTROL LEGEND
DA: Direct-acting thermostat
RA: Reverse-acting thermostat
NO: Normally open damper position
NC: Normally closed damper position
The single function controller provides single functions, i.e.,
DA-NO. Multi-function controllers are capable of providing
DA-NO, DA-NC, RA-NC or RA-NO functions.
Direct Digital Electronic Control Arrange-
ments (Field-Supplied) —
supplied for factory mounting, unless otherwise noted. All
DDC control arrangements include a standard inlet flow sen-
sor, optional 24-volt transformer and control enclosure.
Contact Carrier for detail about mounting field-supplied
controls.
NO CONTROL
D001: 35E box with control box and 24v transformer. Also
used for control enclosure and electric heat.
DXX0: Field supplied, Factory Installed Controls (FMA) with
control enclosure.
DXX1: Field supplied, Factory Installed Controls (FMA) with
control enclosure when Electric Heat is selected.

INSTALLATION

LOCK OUT AND TAG heater electrical disconnect before
working on this equipment. Otherwise, one leg of the 3-leg
heater remains energized. Electrical shock or personal
injury could result.
Step 1 — Install Volume Control Box
1. Move unit to installation area. Remove unit from ship-
ping package. Do not handle by controls or damper
extension rod.
2. Optionally, the unit may have factory-installed hanger
brackets (as shown in Fig. 3).
3. Suspend units from building structure with straps, rods,
or hanger wires. Secure the unit and level it in each direc-
tion. Note that reheat coil is in the heavy end of unit.
